Answer:
Explanation:
Convert mass of bullet 50g in kg
✯ Divide 50 by 1000
⟹ 50/1000
∴ 0.05 kg

</span>Answer: </span>acceleration
Hope This Helps! :3
Answer:
-24 m/s
Explanation:
mass of the bowling ball = 3 kg
time (t) = 0.3 seconds
Force = 24 N
initial velocity u = ???
We know that;
Force = mass × acceleration (a)
So;
24 = 3 × a
a = 24/3
a = 8 m/s²
Also;
From equation of motion; acceleration is given by the relation;
if v = 0
then ;
24 = 0- u
u = -24 m/s
Thus; the initial velocity of the bowling ball when it first touched the mattress = -24 m/s
There is only one pressure this situation would be a "constant pressure" process
Fusion occurs when low mass nuclei, such as hydrogen collide and combine to form nuclei with greater masses.
Fusion could be the world's answer to clean unlimited amounts of energy.
Fusion is extremely difficult to contain and maintain here on earth.
Explanation:
Nuclear fusion is the combination of light atomic nuclei to form nuclei with greater mass.
The sun is powered by chain reaction involving fusion of light hydrogen nuclei to produce a more massive atom of helium.
- As with all nuclear reaction, mass is equivalent to energy. These reactions takes place place in the nucleus of an atom where nuclear forces are broken .
- it is known that nuclear fusion produces far more energy than fission reaction.
- It produces less radioactive wastes and could be the world's clean source of unlimited amount of energy.
- The major problem with fusion is that it is difficult to start and requires a a lot of energy to initiate.
