Answer:
where is volume? formula of density is: mass/volume so volume must be there
Impulse = mass * volume is the most common equation, but you can also calculate impulse by Force * time. So if we increase the force we need to decrease the time.
<h2>The option ( c ) is correct</h2>
Explanation:
When we apply the force on any body , the inertia comes into play . It is the tenancy of the the body to oppose the force which tends to change its state .
In first case the train tries to change its state from rest to motion . Thus the inertia of rest opposes this tendency.
In the second case , the train tries to come from motion to the state of rest . Thus again , inertia opposes it .
Therefore inertia is the factor which creates difficulty in both case . Hence option ( c ) is correct

The correct answer is helium nucleus. An alpha particle has a two neutrons and protons that formed together into a particle which also happens to be very identical to the helium nucleus. However, the helium particles that are being produced by particle accelerator are less to be referred as an alpha particle.
