Answer:
T = 451.26 N
Explanation:
It is given that,
The mass of block, m = 46 kg
Mass of the chain, m' = 19 kg
Length of the chain, l = 1.9 m
Let T is the the tension in the chain at the point where the chain is supporting the block. It is clearly equal to the product of mass and acceleration.
T = 451.26 N
So, the tension in the chain at the point where the chain is supporting the block is 451.26 N. Hence, this is the required solution.
When a camera uses a flash, a fully charged capacitor discharges through an inductor. In 4 * seconds must the 0.100-A current through a 2.00-mH inductor be switched on or off to induce a 500-V EMF.
When a Capacitor is connected to a circuit with Direct Current (DC) source, two processes, which are called "charging" and "discharging" the Capacitor
Given
Inductance = 2 m H
EMF = 500 V
Current = 0.100 A
EMF = L (di/dt)
dt =
L di / EMF
t = L ( i / EMF )
time = 2 * * 0.100 / 500
= 4 * seconds
