The answer might be C ? hope it's right
Could be easy for some people and hard for some people.
Answer:
Explanation:
We know that at pointed corner of a conductor , charge accumulate ie electric field is maximum . Ar pointed corner , radius of curvature will be least . That is why charge leakage is greatest at pointed corner of a charged conductor.
a ) Electric field will be 26.0 kN/C at the point where radius of curvature is greatest .
b ) So electric field will be 66 kN /C at the point where radius of curvature is smallest .
Answer:
1) 0.67HP
2)
Explanation:
1)In order to solve the problem we use the conversion between HP and Watts:
1HP=746Watts
So:
500W*(1HP/746W)=0.67HP
2)The power delivered is equal to the ideal power multiplied the motor's efficiency:
