Answer:
B
Explanation:
KE = mv²/2
The more velocity (speed) is, the more kinetic energy an object has.
Because 10 m/s > 5 m/s, KE at 10 m/s > KE at 5 m/s.
Fossil fuel power plants burn carbon fuels such coal, oil or gas to generate steam that drives large turbines that produce electricity.
The best explanation is the <em>difference</em> between the inside <em>temperature</em> and the outside temperature.
If the player doesn't change his emboucher (muscles and position of his lips), then the pitch produced by the instrument depends only on the physical dimensions of its plumbing, and the speed of sound in the tube.
BOTH of those things change slightly when the temperature changes.
No.
The acceleration of gravity on or near Earth's surface is 9.8 m/s² ,
not 20 m/s² .
If it were 20 m/s², then you would weigh almost exactly double
what you really weigh now.
