Avery light spring is 10.0 cm long with no mass attached to it. when 50.0 g are added, its length increases to 11.25 cm. another 100 g is added and it sets into oscillation. how much time is needed for 100 oscillations.

38.847 seconds

Explanation:

m = Mass

x = Compression of spring

k = Spring Constant

g = Acceleration due to gravity = 9.81 m/s²

From Hooke's law

Additional mass

m = 0.1+0.05 = 0.15 kg

Angular frequency

Time for one oscillation is given by

For 100 oscillations

The time needed for hundred oscillations is 38.847 seconds

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

from wikipedia

can u provide the graph and if its not possible

then i can tell u the segment where the

average time interval starts degrading is the segment where the car is slowing down
