Answer:
Voltage is known as potential or in simpler terms “how fast the electrons flow”. Power is a function of voltage times the volume of electrons (current). Power is the ability to do work and is measured in Watts. The higher the voltage the more power you have with the same current (Watts (power) = Volts x Amps.

Answer:
Density = 1027.3 [kg/m3]
Explanation:
To solve this problem we must use the concept of density which is defined as the relationship between mass and volume, which can be determined by the following equation.
density = m/v
m = mass = 308.19 [gramm] = 0.30819 [kg]
v = volume = 300 [mL] = 0.3 [Lt] = 0.0003 [m3]
density = (0.30819/0.0003)
density = 1027.3 [kg/m3]
Answer:
They investigated Hooke's law.
Explanation:
Answer:
500m/s
Explanation:
From the question we are given the following;
mass per unit length = 4.80 x10^-3 kg/m
Tension T = 1200N
Speed of the wave is expressed as;
v = √T/m
v = √1200/0.0048
v = √250,000
v = 500m/s
Hence the speed at which the wave travels on this string is 500m/s
