Simply, apply the formula
and insert the values of m = mass, v = velocity and E = Energy.
The result will be
, m = 1 kg
The speed would be in a decimal? Or do you want it in a fraction?
The core of a star must be at the temperature of 10,000,000 degrees Celsius for hydrogen fusion to begin.
Answer:
2.8 cm
Explanation:
= Separation between two first order diffraction minima = 1.4 cm
D = Distance of screen = 1.2 m
m = Order
Fringe width is given by
Fringe width is also given by
For second order
Distance between two second order minima is given by
The distance between the two second order minima is 2.8 cm
Answer:
b
Explanation:
The space shuttle, in circular orbit around the Earth, collides with a small asteroid which ends up in the shuttle's storage bay.
This form of collision is called inelastic collision. And inelastic collision momentum is conserved but the kinetic energy is not conserved. Hence the correct option is b. only momentum is conserved.
