Answer:
a) angular acceleration α = 5 rad/sec
b) MOI = 1.25 kgm^2
c) Tention in the string T = 12.5 N
Explanation:
The solution to the question has been provided in the attachment, please refer to that.
Work = (displacement) x (force in the direction of the displacement)
Since none of the force is in the direction of the displacement, the work it does
is zero. Something else is making the object move. It's not the 20N force.
Its visible light <span>or simply </span>light
For astronomical objects, the time period can be calculated using:
T² = (4π²a³)/GM
where T is time in Earth years, a is distance in Astronomical units, M is solar mass (1 for the sun)
Thus,
T² = a³
a = ∛(29.46²)
a = 0.67 AU
1 AU = 1.496 × 10⁸ Km
0.67 * 1.496 × 10⁸ Km
= 1.43 × 10⁹ Km
Explanation:
When,the vehicle has uniform velocity, it's acceleration becomes zero
