In the development of the standard atmospheric model, the variation of the acceleration of gravity with altitude is ignored; that is, the acceleration of gravity is approximated as constant with altitude. Using the Newtonian gravitational model, compute the acceleration of gravity at sea level, 50,000 ft, and 100,000 ft. Based on these computations, describe the accuracy of this approximation.

The accuracy percentage for 50000 ft is 0.47%.

The accuracy percentage for 100000 ft is 0.92%.

Explanation:

Given that,

Height = 50000 ft and 100000 ft

We need to calculate the new acceleration due to gravity

Using newtonian gravitational formula

Where, g = acceleration due to gravity

h = height

R = radius

Put the value into the formula

We need to find the accuracy percentage

Using formula for accuracy

Put the value into the formula

Now, For other height,

We need to calculate the new acceleration due to gravity

Using newtonian gravitational formula

Put the value into the formula

We need to find the accuracy percentage

Using formula for accuracy

Put the value into the formula

Hence, The accuracy percentage for 50000 ft is 0.47%.

The accuracy percentage for 100000 ft is 0.92%.

i think it's 35 meters

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
