Answer:Kg•m/s
Explanation:the SI unit for momentum is kg•m/s
Momentum=mass x velocity
Unit for mass=kg
Unit for velocity=m/s
Therefore they unit for momentum is kg•m/s
Option B (electron) is negatively charged
Answer:
-730KJ
Explanation:
According to the first law of thermodynamics;
Let the total energy of the system be ∆E
Let heat be q and let work the w
Since the energy decreases ∆E is negative
Since work is done on the system w= positive
So;
- 250 = 480 + q
q = -250 - 480
q=-730KJ
Answer:
<h2>9.5 kg</h2>
Explanation:
The mass of the bowling ball can be found by using the formula
p is the momentum
v is the velocity
From the question we have
We have the final answer as
<h3>9.5 kg</h3>
