Answer:
210 N
Explanation:
The change in momentum of the ball is equal (in magnitude) to the impulse given to the pin, according to
(1)
where
is the change in momentum of the ball
F is the force exerted on the pin
is the duration of the collision
For the bowling ball, we have
m = 7 kg (mass)
u = 6.0 m/s (initial velocity)
v = 4.5 m/s (final velocity)
So, the change in momentum (in magnitude) is
We also know the duration of the collision,
And so if we re-arrange eq.(1), we find the force exerted on the pin:
Answer:
An annular Solar Eclipse
Explanation:
Solar eclipse is an event that occurs naturally on Earth when the moon in its orbit is positioned between the Earth and the Sun.Solar Eclipse can be total ,partial or annular.In the total solar eclipse, the moon completely covers the sun where as in the annular solar eclipse the moon covers the center of the Sun leaving outer edges of the Sun to be visible forming the<em> ring of fire.</em>In partial solar eclipse the Earth moves through the lunar penumbra as the moon moves between Earth and Sun.The moon blocks only some parts of the solar disk.Annular solar eclipse happens during new moon and the moon is at its farthest position from the Earth called Apogee.

All moving objects possess </span>kinetic energy, which is determined by the mass and speed of the object.
Answer:
1kg steam will have the maximum energy
