Aball is thrown with initial speed voup an inclined plane. the plane is inclined at an angle above the horizontal, and the ball's initial velocity is at an angle 0 above the plane. choose axes with x measured up the slope, y normal to the slope, and z across it. write down newton's second law using these axes and find the ball's position as a function of time. show that the ball lands a distance r = 2v 2sin 0 cos(0 0)1(g cost) from its launch point. show that for given v and 0, the maximum 0 possible range up the inclined plane is r. = vo /[g(1 + sin oa

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement

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
