The number 3252.6 has 5 significant figures
As an object falls from rest, its gravitational energy is converted to kinetic energy
G.P.E = K.E = mgh
K.E = (80 Kg)(9.8 m/s²)(30 m)
K.E. = 23,520 J
Answer:
1210 ohm
Explanation:
Given :
P=40 W
V=220 V
Now,

Therefore, resistance of bulb will be 1210 ohm
As per Einstein's relation of relativity

here we know that


now here we know that

now from above equation mass of the muon is given as


now for the momentum of muon we can use



so above is the momentum of muon
