What is electric energy
Answer:
electrons
Explanation:
they go through the wires and power our computer tech
Answer:
Electric energy is a form of kinetic energy.
A car capable of a constant acceleration of 3.72 m/s^2 is stopped at a traffic light. When the light turns green, the car starts from rest with this acceleration. At the very same moment, a truck traveling with constant velocity 13.8 m/s passes the car. As the car’s velocity increases, it will eventually move faster than the truck and later overtake it. How far from the light will the car catch up with the truck?
Explanation:
Let t be the time it takes for the car to catch up with the truck.
Using kinematics equations,
Distance by car = ut + 0.5at² = 0 + 0.5 * 3.72 * t².
Distance by truck = 13.8 * t.
Since these distances have to be equal, we have:
0.5 * 3.72 * t² = 13.8t, 1.86t² = 13.8t, t ≈ 7.42s.
Hence the distance is 13.8 * (7.42) ≈ 102.4m.
Contrast scientific laws with traffic laws or other laws devised by people
Answer:
In a nutshell, a scientific law predicts what happens while other laws devised by people usually proposes why certain things happen.
Explanation:
A scientific law is one that predicts the results of certain initial conditions. In order words, it predicts what will happen when certain conditions are fulfilled. A very good example is Newton's 3 laws of motion where like the third law which says to every action, there is an equal and opposite reaction or like in the first law which says a body at rest will remain at rest unless it is acted upon by an external force.
Whereas, other laws devised by people usually provides the most logical explanation as to why things happen the way they do. For example explaining why some children develop certain peculiar health issues when they are newly born.
In a nutshell, a scientific law predicts what happens while other laws devised by people usually proposes why certain things happen.

The chart describes four objects experiencing one or more frictional forces. Which statement explains the type of friction acting on each object?
a. The bike has rolling friction, the sled and the motorcycle have sliding friction, and the elephant has static friction.
b. The bike and sled have sliding friction, and the motorcycle and elephant have static friction.
c. The bike has static friction, the sled and elephant have sliding friction, and the motorcycle has rolling friction.
d. The bike and motorcycle have rolling friction, the sled has static friction, and the elephant has sliding friction.
Answer:
A
Explanation:
I took the test
Rolling friction is demonstrated by a ball or wheel rolling across the ground. Sliding friction is the other form of friction. Because just one side of the body is in contact with the surface, there is a restriction on the body's ability to move. Thus, option A is correct.
What explains the type of friction acting on each object?When something is sitting on a surface, static friction affects it. Because sliding friction is less powerful than static friction, moving a piece of furniture over the floor is simpler once it is moving than before.
Friction that occurs when a moving fluid is positioned between two bodies and an object slides along the surface. Rolling When a thing rolls over another surface, friction is created.
Therefore, The bike has rolling friction, the sled, and the motorcycle have sliding friction, and the elephant has static friction.

A scientist designed a foam container to help keep frozen foods from melting. Which best explains how the foam works? It removes thermal energy from the air inside the container. It removes thermal energy from the frozen foods inside the container. It reduces the amount of thermal energy that is transferred from inside to outside the container. It reduces the amount of thermal energy that is transferred from outside to inside the container.
Answer:
The answer is D
Explanation:
It reduces the amount of thermal energy that is transferred from outside to inside the container.
hope this helps
may i have brainliest pls
The foam reduces the amount of thermal energy that is transferred from outside to inside of the container, which prevents frozen food from melting. Thus, option D is correct.
What is thermal energy?Thermal energy is the energy present in the system that mainly depends on its temperature. Heat is the flow of thermal energy. When temperature increases in the system, the vibration of molecules increases more heat energy is released.
It is also defined as the transfer of heat energy between the systems and also the work done in the transfer of heat. When a substance is changed from one state to another state of matter, heat energy is released.
The material that prevents the heat (thermal energy) passes through them is called a thermal insulator. A foam is considered a good insulator and it is used to prevent frozen food from melting.
Foam is a thermal insulator that prevents heat flow and reduces the amount of thermal energy that is transferred from outside to inside the container.
Hence, the ideal solution is option D.
