The "missing" 4 kg may have escaped the scene of the fire in the
form of hot gases, and as particles of soot and ash that were seen
leaving in the form of "smoke".
Explanation:
Sorry I don't know the answer
<u>Given</u><u>:</u>
- initial velocity, u = 200 m/s
- Final velocity, v = 300 m/s
<u>To</u><u> </u><u>be</u><u> </u><u>calculated</u><u>:</u>
Calculate the acceleration of given object ?
<u>Formula</u><u> </u><u>used</u><u>:</u>
Acceleration = v - u / t
<u>Solution</u><u>:</u>
We know that,
Acceleration = v - u / t
☆ Substituting the values in the above formula,we get
Acceleration ⇒ 300 - 200 / 20
⇒ 100/20
⇒ 5 m/s²
Answer:
C
Explanation:
Angular momentum is the product of moment of inertia and angular velocity.
L = I × ω
Since the planet follows a stable circular orbit, I and ω are constant and non-zero. Therefore, the angular momentum is constant and non-zero.
