True, according to the Kinetic Molecular Theory.
Answer:
Red ball
Explanation:
Two ball of equal mass when fall on the surface from the same height means that both balls have same potential energy.
when the ball collides with the floor both ball posses same velocity.
but according to the statement given that red ball rebounds higher position means that the change of the velocity of the red ball is more the blue ball.
so, the change in momentum of the red ball is more than the blue ball which means the impulse during collision of the red ball will be more.
B. The hormone erythropoeitin increases the production of red blood cells when oxygen levels are low.
Answer:
25 m/s
Explanation:
Centripetal acceleration is the square of the tangential velocity divided by the radius.
a = v² / r
15.625 m/s² = v² / (40 m)
v² = 625 m²/s²
v = 25 m/s
The speed of the car is 25 m/s.
<span>The answer is 15 centimeters. The waves with the
smallest wavelengths (also highest
frequency) have the least capacity to diffract around objects hence have a
shadowing effect, behind the object, especially if the wavelength is small
compared to the object. This is also the reason why high-frequency electromagnetic waves do not have a good reach in mountainous
regions. </span>
