Answer:
<em>k = 25.18 N/m</em>
Explanation:
<u>Simple Harmonic Oscillator</u>
It consists of a weight attached to one end of a spring being allowed to move forth and back.
If m is the mass of the weight and k is the constant of the spring, the period of the oscillation is given by:

If the period is known, we can find the value of the constant by solving for k:

Substituting the given values m=5 Kg and T=2.8 seconds:

k = 25.18 N/m
Answer:
The magnetic field strength of an electromagnet is therefore determined by the ampere turns of the coil with the more turns of wire in the coil the greater will be the strength of the magnetic field.
Explanation:
Answer:
Convective heat transfer is the transfer of heat between two bodies by currents of moving gas or fluid. In free convection, air or water moves away from the heated body as the warm air or water rises and is replaced by a cooler parcel of air or water.

Answer:
v = 0.999981c m/s
Explanation:
Using the time dilation equation

T = stationary time = 100 years
T₀ = 11/12 years = 0.917 years
v = speed of travel in the space = ?
c = speed of light = 3 * 10⁸ m/s


v = 299987395.57 m/s
v = 2.99 * 10⁸ m/s
v = 0.999981c m/s
