Answer:
The correct option is;
Raymond: I think the skateboarder has the same total energy at all points on the ramp
Explanation:
The total energy, also known as the total mechanical energy, is the sum of the kinetic and potential energies of the skateboarder
Given that the potential energy is the energy gained due to elevation, the maximum potential energy is obtained at the top of the ramp, while the maximum kinetic energy, which is the energy due to motion, is at the bottom of the ramp where the skateboarder moves fastest.
However, by the energy conservation principle, the kinetic energy of he skateboarder comes from the conversion of the potential energy, such that the total energy is the same at any particular point on the ramp.
Answer:
Change in the shape size volume and state of a substance
When a solid is heated, it turns into a liquid. As a liquid, a substance has a fixed volume, but its shape changes to fill the shape of its container. For instance, a glass of water is the liquid state of water. ... Gas expands to fill the shape and volume of its container.
Explanation:
Explanation:
It is given that,
Power consumed by toaster oven,
Time taken, t = 6 minutes = 0.1 hour
Energy used by toaster,
Similarly,
Power consumed by toaster oven,
Time taken, t = 9 minutes = 0.15 hour
Energy used by toaster,
Hence, this is the required solution.
