**Answer:**

a) (momentum of the elephant), p1 = 14625 kg×m/s

b) p1 = 609.4×p2

c) (momentum of the hunter), p3 = 720 kg×m/s.

**Explanation:**

a) if m = 1950 kg is the mass of the elephant and V = 7.50 m/s be the speed of the elephant, then the momentum is given by:

p1 = m×V = (1950)×(7.50) = 14625 kg×m/s

b) if m = 0.0400 kg is the mass of the bullet and v = 600 m/s be the speed of the bullet, then the momentum of the bullet is given by:

p2 = m×v = (0.0400)×(600) = 24 kg.m/s

then:

p1/p2 = (14625)/(24) = 609.4

that is, p1 = 609.4×p2

Therefore, the momentum of the elephant is 609.4 times the momentum of the bullet.

c) the momentum og the hunter after missing the elephant is given by:

p3 = m×v = (90.0)×(8) = 720 kg.m/s

Therefore, the momentum of the hunter is 720 kg×m/s.

B. Neutrons or Protons Adding or removing protons from the nucleus changes the charge of the nucleus and changes that atom's atomic number. For example, adding a proton to the nucleus of an atom of hydrogen creates an atom of helium. (Actually, a few neutrons have to be added as well to make the new nucleus stable, but the end result is still helium.)

There is a basic difference<span>, because </span>mass<span> is the actual amount of material contained in a body and is </span>measured<span>in kg, gm, etc. Whereas </span>weight<span> is the force exerted by the gravity on that object mg. Note that </span>mass<span> is independent of everything but </span>weight<span> is different on the earth</span>

In vacuum, going at 2.99×10^8 m/s.

**Answer:**

C. stronger than

**Explanation:**

As Jupiter is 317 times massive than the Earth, its gravitational attraction would be stronger. This is because gravitational attraction force depends on mass and distance. At the same different, massive body will exert greater gravitational pull.

Thus, option c is correct.
