How much force is needed to accelerate a 5 kg mass at 3 m/s/s?
Answers
Explanation:
Force = mass x acceleration
F=m • a
Mass= 3 m/s
Acceleration=5kg
5 x 3 = 15
Force=15N

There was a head-on collision between a compact hybrid car and a SUV.
According to Newton’s 3rd law, the force exerted on each other is the same.
So, why are people in the smaller car more likely to get injured than those in the large one, assuming both cars are equally strong?
Vocabulary: inertia, mass, acceleration, force, unbalanced, balanced, Newton's 2nd Law
Answers
Answer:
hey im back
Explanation:
The reason behind why people in the smaller car are more likely to get injured than those in the large one is greater acceleration of the small car.
What is acceleration?Acceleration is rate of change of velocity with time. Due to having both direction and magnitude, it is a vector quantity. Si unit of acceleration is meter/second² (m/s²).
When There was a head-on collision between a compact hybrid car and a SUV, according to Newton’s 3rd law, the force exerted on each other is the same. But .
As from Newton's 2nd Law, we know that numerical value of force is simply multiplication of mass and acceleration. So, due to having small mass, smaller car suffers more acceleration for same amount of unbalanced force.
This acceleration acts against current inertia of motion of both cars and try to change it. As small car has greater acceleration, people in the smaller car are more likely to get injured than those in the large one although both cars are equally strong.

Does the moon have gravity? How do you know? Support your answer using evidence.
Answers
Answer:
Gravity is experienced on the moon but since the moon is much smaller and has less mass than the Earth, the gravitational pull on the surface is lower compared to that on the surface of Earth.
Explanation:
Yes, the moon has gravity. This is evidenced by the fact that it not only attracts objects on its surface, but it also influences the tides of the Earth's oceans. The moon's gravitational pull creates the distinctive tidal bulges that cause the daily rise and fall of the ocean tides. This interaction between the moon's gravity and the Earth's oceans is evidence of the moon's gravitational field. Additionally, space missions to the moon have shown that objects and astronauts on the moon's surface are subject to its gravitational pull.

Answers
Answer:
39,200J
Explanation:
just took the test
The meteor's potential energy if it has a mass of 10kg at an altitude of 400 m will be 39200 J
What is potential energy ?Potential Energy that depend upon the relative position of various parts of system . It is an energy possessed by an object by virtue of its position or configuration.
mass(m) = 10kg
g (acceleration due to gravity) = 9.8m/s^2
altitude(height (h)) = 400m
Meteor's Potential energy = m * g * h
= 10 * 9.8 * 400 = 39200 J

The work input = _____.
F i ÷ d i
F o ÷ d o
F o × d o
F i × d i
Answers
The work input = Fi × di
How to solve for work input?To solve for work input, you need to know the force acting on an object and the distance it moves in the direction of the force. Work input is defined as the product of force and distance, given by the formula:
Work Input = Force × Distance × cosθ
Where θ is the angle between the force vector and the direction of motion. If the force is applied in the direction of motion, then θ = 0 and cosθ = 1, so the formula simplifies to:
Work Input = Force × Distance
For example, if you are pushing a box with a force of 50 newtons over a distance of 10 meters, the work input would be:
Work Input = 50 N × 10 m × cos(0°) = 500 Joules

See how a block and tackle system can increase your mechanical advantage. You will need two broomsticks, a rope, and two helpers.
A. Give each helper a broom stick and have them stand facing each other holding the broomstick firmly in both hands in a horizontal position. The broomsticks should be at the same level, about two feet apart.
B. Tie one end of the rope to one of the broomsticks. (You may need to have one of your helpers hold the knot firmly in one hand as he or she holds the broomstick to help anchor it.)
C. Wrap the rope around the other broomstick, as in a simple pulley system, and pull on the free end of the rope. Your helpers should resist your pulling. What happens? Can you pull the broomsticks together?
D. Now weave the rope back over the first broomstick, so you have a double pulley. Pull on the free end. What happens now? Can you pull the broomsticks together? What is your mechanical advantage?
E. Try weaving the rope over the broomsticks one or two more times. Describe what happens, and state the mechanical advantage of each situation.
F. Write a summary of what happened and an explanation using the terms: force distance work mechanical advantage

What are the four forms of matter that waves can travel through?
Answers
Answer:
It can be a solid, liquid, gas,plasma,etc. When waves travel through a medium, the particles of the medium are not carried along with the wave.For example, water waves have to travel in water. Sound waves need a solid, a liquid or a gas to travel in.
The four states of matter are gas, liquid, solid and plasma. Waves can travel through all these states of matter but by different transfer modes.
What are waves?Waves are energy transfer through matter. There are two types of waves namely, mechanical waves and electromagnetic waves. Mechanical waves can travel through a medium only whereas, electromagnetic waves can travel through vacuum also.
The four states of matter are liquid , gas , solid and plasma. All of these states are allotting waves to pass through. Through solids the energy is transferred by conduction. and in gases and liquids, convection is the mode for energy transfer.
Only electromagnetic waves can pass through plasma state of matter. When the frequency of the waves is greater than the plasma frequency, then electromagnetic waves can pass through it.

You probably use the term heat many times a day. As an example, when you cook, dinner, you heat your dinner on a hot stove. When you place a piece of cool metal in the sun, it is heated by the sun’s energy. Why is heat the correct term to use in these examples?
A. They show that when objects are touching, they are the same temperature.
B. They show that heat flows from something warmer to something cooler.
C. They indicate that heat is created to raise the temperature of something.
D. They indicate that the kinetic energy of the particles decreases when something is heated.
Answers
Answer: Pretty sure it is B
Explanation:
When you cook, dinner, you heat your dinner on a hot stove. When you place a piece of cool metal in the sun, it is heated by the sun’s energy. Heat is the correct term to use in these cases because they show that heat flows from something warmer to something cooler. So, option(B) is correct.
What is heat?As a result of a temperature difference, energy is transferred from one body to another and is known as heat. The hotter body transfers energy—heat flows—from the cooler body when two bodies with different temperatures are brought together.
An increase in the temperature of the colder body and a reduction in the temperature of the hotter body are typically, though not always, the results of this energy transfer.
A substance can absorb heat without increasing in temperature by transitioning from one physical state (or phase) to another, such as melting, sublimation, boiling, or shifting from one solid form to another (usually called a crystalline transition).
