Question

Определить скорость спутника движущегося по круговой орбите удаленной от поверхности Земли на расстояние 3000км. Радиус Земли 6400км

Answer 1

H=3000км=3*10^6м
R=6400км=6,4*10^6м
G=6,67*10^-11 Н*м^2\кг^2
Mз=6*10^24
v=√G(Mз:Rз+h)

Calculating the Speed of a Satellite in Circular Orbit

To determine the speed of a satellite in a circular orbit at a distance of 3000 km from the Earth's surface, we can use the following formula:

v = √(GM/r)

Where: - v = orbital speed - G = gravitational constant (approximately 6.674 × 10^-11 N m^2/kg^2) - M = mass of the Earth (approximately 5.972 × 10^24 kg) - r = distance from the center of the Earth to the satellite's orbit (radius of the Earth + altitude of the satellite)

Applying the Formula

Using the given values: - Radius of the Earth, R = 6400 km - Altitude of the satellite, h = 3000 km

The distance from the center of the Earth to the satellite's orbit (r) can be calculated as: r = R + h

Substituting the values into the formula: v = √(GM/r)

Calculating the Orbital Speed

Let's calculate the orbital speed using the provided values and the formula.
