Answer: Rn :)))) no explanation needed
Explanation:
The increase in the body temperature of pronghorn, the fastest North American animal, results from the chemical energy of the pronghorn converting into kinetic energy with efficiency less than 100%. The remaining energy is converted into heat energy. Thus, raising the temperature of pronghorn.
Due to the chemical energy it gains both kinetic and heat energy.
Answer:
Claim: The heart pumps more blood throughout the body when one exercises because exercise takes a lot of energy from the body.
Evidence: Heart rate went from 80 bpm to 120 bpm
Reasoning: Doing exercise takes a lot of energy to do, causing the circulatory system to have to work harder and pump more blood throughout the body in order to allow someone to be able to do a task that involves so much movement and energy.
Explanation:
Answer:
Explanation:
They have the same kinetic energy
Answer:
Explanation:
Given
mass of lead piece
mass of water in calorimeter
Initial temperature of water
Initial temperature of lead piece
we know heat capacity of lead and water are and respectively
Let us take be the final temperature of the system
Conserving energy
heat lost by lead=heat gained by water
