Answer:
Explanation:
Relative to ground level it has
PE = mgh = 8(10)(5) = 400 J
Answer:
Maximum height will be 
Explanation:
We have given initial velocity through which basketball is thrown 
Acceleration due to gravity 
At maximum height velocity will be zero
So final velocity v = 0 m /sec
According to third equation of motion 
( Negative sign is due to upward acceleration )

What happens is that if u put gas in a ball and placed in a hot climate it will start burning Bc u have gas inside the ball
Radioactive decay is given by:
N = No x e^(-λt)
We know that N/No has to be 0.05
λ = 0.15
0.05 = e^(-0.15t)
t = ln(0.05)/(-0.15)
t = 19.97 days
C. electrical energy is transformed into light and heat energy
