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

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
