A rocket achieves lift off due to ______. a. inertia
c. centripetal forces
b. action and reaction forces
d. the doppler effect



B. Action and reaction forces


Newton's third law of motion, which states that action and reaction forces are equal and opposite, makes a rocket achieve lift off.

When the engine of a rocket burns fuel, the rocket experiences a thrust (a push) on the front that pushes it upwards. This thrust causes an equal and opposite push on the exhaust gas of the rocket downwards. The burning of the fuel is the action, the thrust, and it causes the rocket to move upwards. The push back on the exhaust gas is the reaction caused by the weight of the rocket.

For the rocket to lift off, the thrust must be greater than the weight of the rocket.

B.) Action and reaction forces helps during lift off of a rocket.

Reducing access to waterways will lead to an increase in human impact on waterways. T/F


Answer: False

A waterway refers to a water body that can be used for the transportation by human population. These includes rives, oceans, lakes, estuary and canals. A waterway should be wide and deep enough to allow the movement of water transportation vehicles like boats and ships. Water transportation is responsible for contaminating the water of waterways. As, the water transportation vehicles releases residues of fuel in the water, which deteriorate the quality of water and makes it unfit for survival of aquatic animal and plant species.

Hence, excess to waterways should be reduced in order to prevent water pollution. Reducing access to waterways will lead to decrease in human impact on waterways.

Therefore, the statement reducing access to waterways will lead to an increase in human impact on waterways is false.

The answer is false. It will decrease human impact due to access being reduced. It sounds like a trick question, but it's not. It is very straight forward. False is your answer young padawan.

Moving water, like that of a river, carries sediment as it moves along its bed. The faster the water flows, the more sediment that is carried and the larger the sediment particles. As the river slows down, the heavier particles of the load will settle out. How can you explain the particle movement based on Newton's laws of motion?


To understand the solution we must know about Newton's laws of motion.

What are Newton's laws of motion?Newton's First law of motion (or the law of inertia)

If a particle is in motion it will be in motion and if an object is at rest then it will be at rest until and unless an external force is acting upon the system.

Newton's Second law of motion, F = ma

The force is the product of the mass of the object and the acceleration of the object.

Newton's Third law of motion,

When two bodies interact then the force applied by them on each other is equal in magnitude and opposite in direction.

Why does the sediment in river water move?

When the water is moving at a high speed it exerts more force on the sediments in the larger sediment therefore, it's easier to move the larger sediment particles as the force by the river water is strong enough to encounter the inertia and the gravitational force.

In the opposite case, when the river slows down, the larger sediment of the load will settle out because of the reduced force. the force applied by the river water is not enough to move the particle (or encounter the inertia and the gravitational force).

Learn more about Newton's laws of motion:


Well newton's law is esstenaily how gravity works. so the force in this case water moves, the more the object (sediment) will go farther. And when the force is lessened the object will eventually come to a dead stop.

Olivia wants to find out whether a substance will fluoresce. She says she should put it in a microwave oven. Do you agree with her? Why or why not?


Answer: Hello there!

While some substances will show fluorescence when putting inside a microwave, there are some other substances that will react under other situations, for example, some of them may react to UV light or X-rays.

So she may find that the substance is fluorescent by putting it in the microwave, but if the substance does not react, this doesn't mean that the substance is not fluorescent.

Olivia wants to find out whether a substance will fluoresce, I do not agree with putting it in a microwave oven as it might cause an explosion.

What is fluoresce?

Fluoresce is simply defined as the absorption of radiation at a wavelength followed by almost instantaneous radiation at a different wavelength.

In conclusion, microwaves react with metallic substances to cause explosions.

Uses of Microwaves

  • Communication

Most wireless transmission systems are based on microwave technology. They are suitable for transmitting signals over long distances. Microwaves are used as a medium for transmitting information between mobile devices.

  • Cooking

One of the most important uses of microwaves in the routine life of human beings is in microwave ovens. When you place food inside the chamber, microwaves bounce around the oven and heat the food through radiation.

  • Medical Uses

Microwaves cause heating. This property has been harnessed to create targeted dielectric thermal desiccation of human tissue. This process is referred to as microwave ablation. Microwaves are also used in cancer treatments.

To know more about microwaves, follow the link given below.



1.) Radar

2.) Cancer Treatment

4.) Cooking


Microwaves are a type of electromagnetic radiations, like radio waves, X-rays, Gamma Rays, ultraviolet radiation. Microwaves has a wide range of applications. It has frequency range 1GHz to 300GHz and has smaller wavelengths. As microwaves do not bend by any obstacles coming in their path, So, it can be used in radar. In cancer treatment, it is used to increase the temperature of tumor cells by high-power microwaves, results in turns cell membrane damage, which in results destruction of cancer cells. In cooking, microwave heat food like the sun rays your face i.e by means of radiation. It increases the energy of molecules inside food, which results in cooking or heating the food.

Riley is doing an experiment working with friction. He wants to find two ways to modify an object that could increase or decrease the same type of friction


If the type of friction is sliding friction, it may be increased by increasing the roughness of the surface and may be decreased by smoothing the surface or applying a lubricant.


As we know that friction force is a contact force which opposes the relative motion between two surfaces in contact.

So here we can change the force between two surface when they move relative to each other.

Here when Lubrication is used between two surface then the relative motion of two planes becomes easy. So by lubrication of the surface either by oil or by smoothing the plane we can say that friction force will be reduced.

Also friction force depends on the effective contact points between two surfaces. So as we increase the contact points between two surfaces then the effective frictional force will increase.

Also we know that friction force is given by

now as we increase the normal force between two contact planes either by increasing the weight or by applying normal external force we can say that friction force will increase.

A 2700 Ohm resistor and electric circuit draws a current of 2.4 Milliamperes the total charge that passes through the resistor in 15 seconds is


The total charge (Q) that passes through the resistor in 15 seconds is 3.6 × 10⁻² Coulombs

The total charge (Q) inside an electric circuit is the total electrical current energy stored in the circuit per the dissipated energy in one period of time.

The total charge (Q) can be expressed by using the relation:

  • Q = It

Which of the following objects has the most kinetic energy? a car going 60 miles per hour
a spring that is compressed
a rock sitting on the edge of a cliff
a bicycle going 10 miles per hour


The car going at 60 mph will have the maximum kinetic energy.

What is Kinetic energy?

The energy possessed by a body by virtue of its motion is called kinetic energy of the body. Mathematically, we can write kinetic energy as -

E[K] = 1/2mv²

Given are the examples which we come across in our day to day life.

Now, the rock sitting on the edge of a clip and the compressed spring will have potential energy in the form of gravitational and elastic potential energy. Now, the kinetic energy of a body is directly proportional to the square of the velocity. Thus, for a car with velocity of 60 mph will have more kinetic energy than the bicycle with 10 mph. So, the object with maximum kinetic energy will be of the car going at 60 miles per hour.

Therefore, the car going at 60 mph will have the maximum kinetic energy.

The plane flight covers 400 miles in the first hour. As you approach the landing site, it takes you an hour to cover the last 200 miles. This is an example of (2 points) positive acceleration. velocity. instantaneous speed. negative acceleration.



negative acceleration


Acceleration is defined as the rate of change in velocity to the time taken.

Acceleration is positive if the final velocity is ore than the initial velocity.

Acceleration is negative if the final velocity is less than the initial velocity.

Here, the velocity of plane is decreasing because it is landing, so the acceleration is negative.

Miles per hour is velocity so I agree with you. Without seeing any associated question, though, it's hard to say. If the question is, find the average velocity, then velocity is correct. But since change in velocity is negative, that is also negative acceleration.

What change of state occurs when wet clothing on a washing line dries out?


It is connected with vapour pressure, which is determined by the amount of water in the atmosphere and humidity.

When the air is 100% saturated with water vapour there will be a dynamic equilibrium where as much water condenses out of the air onto the clothes, as evaporates from the clothes into the air. If humidity is less than 100%, then there will be more evaporation than condensation and the clothes will become drier.

If the humidity is very low, either because the air is hot and can hold more water, or because there is just very little moisture in it, then the evaporation will proceed more quickly. If there is a wind this will speed the drying up because 'fresh' air, with low humidity is constantly passing over the clothes.

Are electrons negatively charged? ›

Electrons are negatively charged subatomic particles found in the outermost regions of atoms. They are considered to be both partially particle-like and partially wave-like, depending on the scenario, according to West Texas A&M University. Electrons are essentially the reason atoms can interact with other atoms.

What makes electrons move? ›

This force is called electromotive force, EMF, or voltage (V). Sometimes it is convenient to think of EMF as electrical pressure. In other words, it is the force that makes electrons move in a certain direction within a conductor.

Why do electrons move? ›

When electric voltage is applied, an electric field within the metal triggers the movement of the electrons, making them shift from one end to another end of the conductor. Electrons will move toward the positive side.

How were electrons created? ›

In the first moments after the Big Bang, the universe was extremely hot and dense. As the universe cooled, conditions became just right to give rise to the building blocks of matter – the quarks and electrons of which we are all made.

How many electrons are in each shell? ›

Each shell can contain only a fixed number of electrons: the first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on. The general formula is that the nth shell can in principle hold up to 2(n2) electrons.

What is free electron in chemistry? ›

The electrons that are not bound within the atom and free to move are called free electrons. As we know that the movement of electrons is the electric current. So, the free electrons tend to move freely and can conduct electricity. Metals are good conductors of electricity and thus they possess free electrons.

What are atoms described as? ›
