Explanation

To calculate the moment of inertia of the Earth about its diameter, we can use the formula for the moment of inertia of a sphere:

I = (2/5)MR^2

where:

I = moment of inertia

M = mass of the Earth (10^25 kg)

R = radius of the Earth (diameter/2 = 12800 km / 2 = 6400 km = 6.4 × 10^6 m)

Plugging in the values, we get:

I = (2/5) × 10^25 kg × (6.4 × 10^6 m)^2

= (2/5) × 10^25 kg × 4.096 × 10^13 m^2

= 1.6384 × 10^38 kg m^2

≈ 1.64 × 10^38 kg m^2

The Waxing moon refers to the phase when the visible portion of the moon is increasing.

It moving from new moon towards full moon.

Explanation

For high current flow in electrical circuits, one needs thick conductors.

Thick conductors can handle larger currents with lower resistance, reducing heat and power loss.

Explanation

An algorithm is a sequence of instructions in a computer language that is designed to solve a specific problem or achieve a particular goal.

It's a step-by-step procedure to get the desired results.

Explanation

• Sir Isaac Newton postulated the law of universal gravitation.
• Newton's law of gravitation states that every point mass attracts every other point mass by a force acting along the line intersecting both points.

The formula to calculate this force is:

F = G * (m1 * m2) / r^2

Where:

• F is the force of gravity
• G is the gravitational constant
• m1 and m2 are the masses of the two objects
• r is the distance between the centers of the two objects
