What is the momentum of a 48.2N bowling ball with a velocity of 7.13m/s?
Vesna [10]

Answer:

Momentum, p = 34.937 kg-m/s

Explanation:

It is given that,

Force acting on the bowling ball, F = 48.2 N

Velocity of bowling ball, v = 7.13 m/s

We have to find the momentum of the ball. Momentum is given by :

p = mv........(1)

Firstly, calculating the mass of bowling ball using second law of motion. The force acting on the ball is gravitational force and it is given by :

F = m g    (a = g)

m=\dfrac{F}{g}

m=\dfrac{48.2\ N}{9.8\ m/s^2}

m = 4.9 kg

Now putting the value of m in equation (1) as :

p=4.9\ kg\times 7.13\ m/s

p = 34.937 kg-m/s

Hence, this is the required solution.

Arlecino [84]

Answer:

e. B and C

Explanation:

When the sun ignited in our solar system evaporation of the material closest to the sun took place. The low density material were pushed further. The rocks that remained formed the protoplanets. As, the early solar system was very hot parts of the protoplanets melted. This caused the melted material to flow towards the center of the planet. As the mass of the planet increases this causes more accretion which causes materials of different densities to mix.

During summer in the northern hemisphere _____.
Kipish [7]
For part of our orbit the northern half of Earth is tilted toward the Sun. This is summer in the northern hemisphere; there are longer periods of daylight, the Sun is higher in the sky, and the Sun's rays strike the surface more directly, giving us warmer temperatures
