A wheel is rotating at 20rad/s is brought to rest by a constant torque in 4 seconds. If the moment of inertia of the wheel is 0.3 kgm^2, what is the angle rotated by the wheel in the first 2 seconds?
Given conditions can be written as, ω1 = 20 rad/s I = 0.3 kgm 2 t = 4 s ∵…
The mass of the earth is 6 x 10²⁴ kg. The distance between the earth and the Sun is 1.5x 10¹¹ m. If the gravitational force between the two is 3.5 x 10²² N, what is the mass of the Sun?
the given can be listed as mass of earth , m = 6 x 10²⁴ kg. distance bet…
