Answer:
Mechanical energy
Explanation:
A car changes chemical energy from fuel into thermal energy and mechanical energy.
Mechanical energy can be defined as the type of energy that is possessed by an object due to its motion or position. Mechanical energy is the sum of potential energy and kinetic energy, that is, the sum of energy in motion and stored energy. Examples of mechanical energy includes driving a car, riding a bicycle, listening to music etc.
Types of mechanical energy
1. Motion energy (kinetic energy)
2. Stored energy(potential energy)
Mechanical energy = Kinetic energy + Potential energy
Based on what we know, we can confirm that the wave behavior being observed when light passes through media of different densities is refraction.
<h3>What is refraction?</h3>
This is a term used to explain the behavior of light as it moves through distinct mediums. This behavior includes a change in direction of the light due to its change in speed.
Therefore, the wave behavior being observed when light passes through media of different densities is refraction.

Answer:
<h3>The answer is 45 kg • m/s</h3>
Explanation:
The momentum of an object can be found by using the formula
<h3>momentum = mass × velocity</h3>
From the question
mass = 15 kg
velocity = 3 m/s
We have
mass = 15 × 3
We have the final answer as
<h3>45 kg • m/s</h3>
Hope this helps you
Answer:
15N South
Explanation:
It is 15N South because the two 15N cancel out each other and then you subtract 5N from the 20N and then you get left with 15N. and the 20N is bigger and it is going South.So the answer is 25N south.
