A moving ball primarily has kinetic energy (motion).
Elastic energy comes into effect if the ball is compressed or stretched, like in the case of a bouncing ball.
Theoretical problems usually have perfect pr controlled conditions, but a moving ball in real life would be compressed or changing with its contact with the ground.
If you want more help or could provide more context, feel free to ask.
If this is a question on a test or quiz and its asking what type of energy a 'moving' ball has, generally they want you to think about what causes the movement (in this case, kinetic), because there is always a lot of other energy being transferred and happening at the same time (i.e., thermal, sound).
Answer:
a=2m/s^2
Explanation:
If a cart of 4 kg mass has a force of 8 newtons exerted on it, what is its acceleration
first foremost, we define basic terms
Mass=is the quantity of matter in a body ,kg
Acceleration= change in velocity per time(m/s^2)
Force= Is that which tends to change a body's state of rest or uniform motion in a straight line.
It is also the pull or push on a body.
From newton's second law of motion which states that rate of change in momentum is proportional to the force applied. Where k=1
Fαm(v/t)
F=km(v/t)
K=1
f=ma
Since v/t= acceleration
velocity/time=accel
8=4a
a=8/4
a=2m/s^2
9.40 V
2.40 V
zero
Answer:
false
Explanation:
The forehand stroke is a basic shot in tennis, variations are allowed in order to boost performance (power, topspin and accuracy) of the player. Some guidelines to choose the correct forehand stroke are to visualize the correct stroke, position correctly, correct footwork and selecting shot location.
B: a chain reaction
C: a fusion of uranium nuclei
D: krypton atoms to split into strontium and xenon
The correct answer is:
B: a chain reaction
Explanation:
A chain reaction is a series of reactions where a reactive output or by-product produces additional reactions to earn a place. In a chain reaction, extremely feedback leads to a self-amplifying series of events.
Chain reactions are one way that systems which are not in thermodynamic stability can release energy or improve entropy in order to enter a state of greater entropy.
Wien's law
Kepler's law
the spectral law
Answer:
The correct choice is
Wien's law
Explanation:
According to Wien's law, wavelength of maximum intensity of emission of black body radiation is inversely proportional to absolute temperature (T) of the black body. The formula for the law is given as
where
= wavelength of maximum intensity
T = temperature
b = Wien's constant
