Calculate the magnitude of the linear momentum for the following cases.(a) a proton with mass 1.67 calculate the magnitude of the linear momentum for 10-27 kg, moving with a speed of 5.45 calculate the magnitude of the linear momentum for 106 m/skg ? m/s(b) a 16.0-g bullet moving with a speed of 435 m/skg ? m/s(c) a 72.5-kg sprinter running with a speed of 11.0 m/skg ? m/s(d) the earth (mass = 5.98 calculate the magnitude of the linear momentum for 1024 kg) moving with an orbital speed equal to 2.98 calculate the magnitude of the linear momentum for 104 m/s. kg ? m/s

(a)

The magnitude of the linear momentum of an object is given by

where

m is the object's mass

v is its speed

In this case, we have

(mass of the proton)

(speed of the proton)

So, the momentum is

b) 7.0 kg m/s

In this case, we have

m = 16.0 g = 0.016 kg (mass of the bullet)

v = 435 m/s (speed of the bullet)

By applying the same formula, the linear momentum is

c) 797.5 kg m/s

In this case, we have

m = 72.5 kg (mass of the sprinter)

v = 11.0 m/s (speed of the sprinter)

By applying the same formula, the linear momentum is

d)

In this case, we have

(mass of the Earth)

(speed of the Earth)

By applying the same formula, the linear momentum is

thermal energy is the answer

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
