Average velocity is equal to the total distance traveled over the time elapsed.
Answer:
Explanation:
T=2π√l/g
to solve this for l we have to remove the square root in order to finish square root we have to take square on both side so the equation become
T²=4π²l/g
multiplying g on both side
T²g=4π²l
now dividing 4π² on both side
T²g/4π²=l
so l=T²g/4π²
Answer:
I = 6 A
Explanation:
Given that,
Power of an electric heatr, P = 1.38 kW
The voltage of the mains supply, V = 230 V
We need to find the current through the heater. The electric power in terms of voltage and current is given by :

So, the current through an electric heater is 6 A.
