The correct answer is b i believe
The largest transition metal is copernicium with 112 protons.
Explanation:
Average power = change in energy / change in time
P = ΔE / Δt
P = (½ mv²) / t
P = (½ (0.825 kg) (0.620 m/s)²) / (0.021 s)
P = 7.55 Watts
The speed is 0.2 meter per minute.
There is not enough information given in the question to determine the velocity.
Given : Time taken to reach the maximum height t=3 s a=−g=−10m/s

The initial velocity of the ball can be calculated by,
Using v=u+at
∴ 0=u−10×3 ⟹u=30 m/s
Using S=ut+
