Answer:
how you can convert electrical energy to mechanical energy
Explanation:
In the Electric Motor lab, what did you attempt to demonstrate with the electric motor?
In the Electric Motor lab, the experiment usually demonstrate energy conversion process, from electrical energy to mechanical energy. This mechanical energy can also be converted back to electrical energy using a generator.
Therefore, what you attempted to demonstrate with the electric motor, is how you can convert electrical energy to mechanical energy
Answer:
14 m/s
Explanation:
Using the principle of conservation of energy, the potential energy is converted to kinetic energy, assuming any losses.
Kinetic energy is given by ½mv²
Potential energy is given by mgh
Where m is the mass, v is the velocity, g is acceleration due to gravity and h is the height.
Equating kinetic energy to be equal to potential energy then
½mv²=mgh
V
Making v the subject of the formula
v=√(2gh)
Substituting 9.81 m/s² for g and 10 m for h then
v=√(2*9.81*10)=14.0071410359145 m/s
Rounding off, v is approximately 14 m/s
Answer; transverse wave
Explanation;
In transverse waves the particles vibrate perpendicular to the wave's motion.
