Speed=Distance/Time. so you need to do distance/speed to get time. 3.84/4.32= .88888888889 seconds to get to his food bowl
Answer:
The number of turns in the secondary coil is 48.
(B) is correct option.
Explanation:
Given that,
Number of turns on primary coil= 1000
Primary voltage = 2500 V
Secondary voltage = 120 v
We need to calculate the turns in the secondary coil
Using relation between voltage and number of turns in primary and secondary coil

Put the value into the formula



Hence, The number of turns in the secondary coil is 48.
Answer:
Work = Force × Distance
