i cant solve this!
Mybe i can solve another question!
(d) Acceleration is a vector quantity
Nuclear fission is seperating an atom so product is b.
Energy is released during nuclear fussion. Mass is converted into energy because E=mc^2, this is the energy that is released
Answer:
Explanation:
velocity of light in a medium of refractive index V = V₀ / μ
V₀ is velocity of light in air and μ is refractive index of light.
time to travel in tube with air = length of tube / velocity of light
8.72 ns = L / V₀ L is length of tube .
time to travel in tube with jelly = length of tube / velocity of light
8.72+ 1.82 = L / V L is length of tube .
10.54 ns = L / V
dividing the equations
10.54 / 8.72 = V₀ / V
10.54 / 8.72 = μ
1.21 = μ
refractive index of jelly = 1.21 .
Answer:
Maximum velocity will be 17.651 m /sec
Explanation:
We have given a rope breaks when tension reaches 205 N
Mass m = 0.477 kg
Radius of the circle r = 0.725 m
Tension in the rope is given by
v = 17.651 m /sec
