Hello There!
It takes the planet Mars around 24 hours, 37 minutes, 23 seconds to rotate on its axis. This is around the same amount of time that it takes our planet to rotate once on its axis.
B is the correct answer . That make the most sense
Answer:
210m/s
Explanation:
To find the speed of wave you need to multiply the wave length with the frequency.
<u>Answer;</u>
<em>The moving car transfers kinetic energy to the parked car. </em>
<u>Explanation;</u>
- Energy is the ability of work to be done. It is measured in joules. The energy in an object depends on whether an object is in motion or at rest.
- Kinetic energy is the energy possessed by a body in motion. Calculated by 1/2mv², where m is the mass of the body and v is the velocity of the body in motion. Therefore, the moving car possess kinetic energy.
- When a body is at rest it posses potential energy. Thus, the parked car possessed kinetic energy which changed when it was hit by the moving car as the kinetic energy of the moving car was transferred to the parked car.
