Answer:
The momentum of the ball is 500 kg·m/s
Explanation:
The momentum is given by Mass × Velocity
The given parameters are;
The mass of the box = 10 kg
The velocity by which the box is sliding = 50 m/s
Therefore, the momentum of the ball is given as follows;
The momentum of the ball = 10 kg × 50 m/s = 500 kg·m/s
The momentum of the ball = 500 kg·m/s
Answer:
Meteoroids
Explanation:
Meteoroids are small masses of rocks or metallic bodies that often found to orbit around the Sun. The size of a meteoroid is smaller in comparison to the asteroids. The elements that are found in the meteoroids are extraterrestrial nickel and iron. Meteoroids are often formed by the fragments from bodies present in universe such as Mars or Moon and thrown into space by an impact. After formation they often come in the range of attraction of Sun and start orbiting around it.
Answer:
correct option is E
power lens is - 1.667 D
Explanation:
Given data
infinity = 60 cm
to find out
power lens
solution
we know here infinity v = -60 cm because object at infinity
and we take u = - infinity
so we know that
1/f = 1/v - 1/u
1/f = 1 / -60 - 1 / -infinity
so
1/f = - 1/60
f = - 60 cm = 0.60 m
and we know power of lens = 1/f
so here
power = 1 / -0.60
power = - 1.667 D
so correct option is E
power lens is - 1.667 D
