Answer 1

Находим по формуле F=Gm1m2/R^2, где G=6,67x10^-11

Answer 2

Calculation of Gravitational Force

To calculate the gravitational force between two bodies, we can use Newton's law of universal gravitation, which states that the force of gravity between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

The formula for gravitational force is:

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

Where: - F is the gravitational force between the two bodies, - G is the gravitational constant (approximately 6.67430 × 10^-11 N m^2/kg^2), - m1 and m2 are the masses of the two bodies, and - r is the distance between the centers of the two bodies.

In this case, we have two bodies with masses of 30 kg and 40 kg, respectively, and they are located at a distance of 1 meter from each other.

Plugging these values into the formula, we get:

F = (6.67430 × 10^-11 N m^2/kg^2) * (30 kg * 40 kg) / (1 m)^2

Now let's calculate the gravitational force using these values.

Calculation:

F = (6.67430 × 10^-11 N m^2/kg^2) * (30 kg * 40 kg) / (1 m)^2

F = (6.67430 × 10^-11 N m^2/kg^2) * (1200 kg^2) / 1 m^2

F = 8.00916 × 10^-9 N

Therefore, the gravitational force between the two bodies with masses of 30 kg and 40 kg, located at a distance of 1 meter from each other, is approximately 8.00916 × 10^-9 N.
