To find the momentum of an object, we multiply its mass and velocity together. Using this method, a bowling ball with a mass of 7.10 kg moving at a velocity of 5 m/s has a momentum of 35.5 kg * m/s.
The subject of your question involves calculating momentum. It's based on the principles of Physics. Momentum is defined as the product of an object's mass and its velocity. It's crucial in understanding motion, specifically related to the concepts of force and mass.
To calculate the momentum of the bowling ball, the formula p = mv is used where 'p' represents momentum, 'm' stands for mass and 'v' is the velocity. In this case, the mass of the bowling ball is 7.10 kg and its velocity is 5 m/s.
So, multiplying these together (7.10 kg x 5 m/s), the resulting momentum of the bowling ball is 35.5 kg * m/s.

Explanation:
KE = 1/2 mv²,
where KE is the kinetic energy,
m is the mass,
and v is the velocity.
Given m = 1500 kg and v = 30 m/s:
KE = 1/2 (1500 kg) (30 m/s)²
KE = 675,000 J
KE = 675 kJ
Answer: 20 minutes
Explanation:
Given the following :
Average speed of train = 120km/hr
Distance = 40km.
The time take by the train moving at an average speed of 120km/hr to cover a distance of 40km due is ;
Recall:
Speed = distance / time
Therefore,
Time taken = distance covered / speed
Time taken = 40km / 120km/hr
Time taken = 1/ 3 hr
Therefore, 1/3 rd of an hour equals
1/3 × 60 = 20 minutes.
Time taken) 20 minutes
Time taken by tain to cover distance is 20 minutes as:
Distance= 40 km
Speed= 120 km/h
Time= distance/speed
= 40/120
= 1/3 hour
= 20 min
or =0.33 hrs

Nuclear energy is released from an atom through one of two processes: nuclear fusion or nuclear fission. In nuclear fusion, energy is released when the nuclei of atoms are combined or fused together. But isn't rapidly release
