The gravitational force F acting on a satellite at height h is given by F = GmM/(R+h)^2, where G is the gravitational constant.

Gravitational acceleration is directly proportional to mass, so if the mass doubles, g also doubles.

Gravitational acceleration is directly proportional to mass; thus, if the mass doubles, g also doubles.

If the mass of the Earth doubles, the acceleration due to gravity also doubles, as it is directly proportional to mass.

Weight is proportional to mass; thus, if the Earth's mass doubles, the weight of an object on its surface also doubles.

If the mass of the Earth doubles, the gravitational force on an object at its surface would also double.

F ∝ M; if M doubles, F also doubles.

F = G * (m1 * m2) / r², doubling the mass of Earth doubles the force.

Gravitational force is directly proportional to mass. If mass doubles, force also doubles.

Weight is directly proportional to mass. If the Earth's mass doubles, the weight of the object also doubles.

If the mass of the Earth increases, the gravitational force experienced by an object on its surface would increase.

Mean of 10 numbers = 50, so total sum = 500. Sum of last 5 numbers = 500 - 200 = 300. Mean of last 5 = 300 / 5 = 60.

The sum of the numbers is calculated as mean * number of items = 25 * 12 = 300.

Sum = Mean * Number of observations = 10 * 5 = 50.

Total sum = Mean * Number of values = 12 * 8 = 96.

Variance is the square of the standard deviation. Therefore, variance = 5² = 25.

Coefficient of Variation = (Standard Deviation / Mean) * 100 = (4 / 20) * 100 = 20%.

Variance = (Standard Deviation)² = 5² = 25.

Total sum = Mean * Number of values = 20 * 10 = 200

Total sum = Mean * Number of values = 20 * 5 = 100

Variance is the square of the standard deviation. Therefore, variance = 5² = 25.

Total sum = Mean * Number of values = 30 * 10 = 300.

Coefficient of Variation = (Standard Deviation / Mean) * 100 = (10 / 50) * 100 = 20%.

Variance is the square of the standard deviation. Therefore, variance = 10² = 100.

Standard deviation is the square root of variance. Therefore, SD = √25 = 5.

Total sum = Mean * Number of values = 50 * 10 = 500.

Total sum = Mean * Number of elements = 50 * 10 = 500.

The total sum is 500. Increasing one number by 10 gives a new total of 510. New mean = 510 / 10 = 51.

Total sum = Mean * Number of items = 12 * 6 = 72.

Total sum = Mean * Number of items = 12 * 6 = 72.
