Answer: m= 35.6 kg
Explanation:
For finding the mass of the stone we have the formula
v= 
Here, Tension= m*g = m*9.81
and linear mass density= 
Linear mass density= 
Linear mass density= 0.0127 kg/m
Velocity= 
Velocity= 2 * 
Velocity= 165.8 m/s
So putting all these values in equation we get
v=
165.8= 
Solving we get
m= 35.58 kg
or m= 35.6 kg
Answer: "converted"
Energy can be converted from one form to another
Explanation:
The law of conservation of energy states that energy can neither be created nor destroyed but converted from one form to another.
For instance:
- an electric generator convert mechanical energy to electrical energy
- a solar panel system convert solar energy to electrical energy.
- an electric pressing iron convert electrical energy to heat energy
Thus, energy can be converted from one form to another
Answer:
Vdc=10V
Explanation:
in a closed loop consisting of a super charged capacitor and an inductor, the super charge capacitor acts as a supply when the loop is closed, at t=0, the emf stored in the capacitor is 10V (q/c); and at that same time Vl= voltage across the inductor or loop too would be 10V,
if the loop remains closed for a longer period, the inductor would absorb energy from the capacitor till it dissipates all charges with itself.
The term used is " WORK".
I'm really sorry it's not one of the choices.
Answer:
When an electric current flows, the shape of the magnetic field is very similar to the field of a bar magnet
