Asoap-box derby race car sits on the starting ramp. the ramp is elevated at an angle of 8.5 degrees. the angle between the gravity vector and the ramp surface is a . the force of gravity on the car is 1225 n. the normal force of the track on the car is 1210 n. the frictional force of the track on the car is 15.2 n. what is the net force on the car?

Explanation:

given,

angle of inclination with the horizontal = 8.5°

force of gravity = 1225 N

normal force on car  = 1210 N

frictional force = 15.2 N

net force = ?

equating horizontal forces

F_x = -165.87 N

equating vertical forces

F_y = -1.54 N

net force

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
