Answer:
2 the speed of the second ball is larger than that of the first one
Explanation:
Using the equations of motion
The second ball was thrown up , on getting to its highest point V=0, H=1/2gt^2
The second ball was. Now has two heights , the distance from the rooftop and the height it reached when the ball was thrown up.
v^2= u^2+2a(H1+H2)
The first ball has a velocity of v^2=2gH
Therefore the second ball velocity is larger than the first ball
Answer:
Option A (1.51 m) is the appropriate option.
Explanation:
The given values are:
Speed of wave,
= 362 m/s
Period,
= 4.17
Now,
⇒ 
then,
⇒ 
⇒ 
⇒ 
Density = mass /volume = 9.2/10 = 0.92 g/cm3. Hope this helps you!
so first your going to use v=Δd/Δt given you the answer 80 i think that's right
Kinetic energy is the kind of energy present in a body due to the property of its MOTION.
Potential Energy is the type of energy present in a body due to the property of its STATE.
