The formula for solving the inertia (I) is I=mr² where "m" represents the mass of an object and "r" represents the perpendicular distance to the rotation axis.
item 1= 100 kg rock
Item 2= 5kg book
item 3= 60kg person
item 4=2000kg car.
The answer is the last item which is a 2000kg car.
Answer: static electricity
Explanation: The movement of charged particles through a wire or other medium is called current or electricity. There is also static electricity, which results from an imbalance or separation of the positive and negative charges on an object. Static electricity is a form of electrical potential energy
Answer:
v = 3.6 m/s
Explanation:
given,
Inclination of the ramp, θ = 33⁰
Distance of the rope, d = 1.70 m
initial speed = ?
using conservation of energy

h = d sinθ
h = 1.7 x sin 33° = 0.926 m
moment of inertia of the solid ball
we know, v = r ω





v = 3.6 m/s
Hence, initial speed of the solid ball = 3.6 m/s
Energy is absorbed by the atom.
Emission lines occur only in the case of transitions from higher to lower energy levels in which energy is emitted.
