Asatellite is put into an elliptical orbit around the earth. when the satellite is at its perigee, its nearest point to the earth, its height above the ground is hp = 229.0 km, and it is moving with a speed of up = 8.050 km/s. the gravitational constant g equals 6.67 x 10-11 mº.kg-1.5-2 and the mass of earth equals 5.972 x 1024 kg. when the satellite reaches its apogee, at its farthest point from the earth, what is its height ha above the ground? for this problem, choose gravitational potential energy of the satellite to be 0 at an infinite distance from earth. km

The height above the ground is 1279.51 km

Solution:

As per the question:

Height above the ground,

Speed of the satellite,

Gravitational constant,

Mass of the Earth, m =

Now,

The distance of the earth from the perigee is given by:

where

Now,

To calculate the distance of the earth from the earth from the apogee:

Height above the ground,

speed

ratio of distance traveled to time interval

net force

vector sum of forces on object

object

source of diverging light rays either luminous or illuminated

don't remove my answer im trying my best to answer them

explanation:

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
