Answer:
75457.54816 N
Explanation:
= Initial force
= Weight of car = 11547.83 N
= Smaller radius = 5 cm
= Larger radius = 19.56 cm
From Pascal's law we have
The force is 754.57548 N
Answer:
A force is any interaction that, when unopposed, will change the motion of an object
Explanation:
Answer:
The resistance is .
Explanation:
Given that,
Power = 259 kV
Current = 429 A
Resistance
We need to calculate the current in each insulator
Using formula of current
Put the value into the formula
So all 95 insulators are in parallel
We need to calculate the resistance
Using formula of resistance
Put the value into the formula
Hence, The resistance is .
Answer:
By induction method
Explanation:
Induction method involves charging an electrically neutral body by bringing it in contact with an electrically charged body.
For the electrophus, a charge opposite that on the slab is induced on the side in contact with the slab; driving the opposite charge (this will be the same as that on the slab) to the other end of the elctrophus. Touching the electrophus removes the charge opposite the charge induced on the electrophus by the charged slab either by drawing up charge from the earth or taking the charge to earth (depends on the charge. A negative charge is drawn to earth while a positive charge draws up electrons from the earth)
