Answer:
t = 5.89 s
Explanation:
To calculate the time, we need the radius of the pulley and the radius of the sphere which was not given in the question.
Let us assume that the radius of the pulley (
) = 0.4 m
Let the radius of the sphere (r) = 0.5 m
w = angular speed = 150 rev/min = (150 × 2π / 60) rad/s = 15.708 rad/s
Tension (T) = 20 N
mass (m) = 3 kg each
Substituting values:
We will first record its mass and then its volume by measuring its dimensions
then divide mass by volume and will get density of regular solid
Answer:
Explanation:
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
= Mass of sphere = 2000 kg
= Mass of other sphere = 2.1 kg
r = Distance between spheres
Force of gravity is given by
The gravitational force is
The gravitational force is
Answer:
Specific gravity for liquids is nearly always measured with respect to water at its densest
Explanation:
Hey :)
The water potential of pure water<span> in an open container is zero because there is no solute and the pressure in the container is zero</span>
