Question

define derive centripetal acceleration expression
$a = 4 {\pi}^{2} r {n}^{2}$
​

Answer 1

Explanation:

Calculate the value of R in the balance conduction of the Wheatstone bridge, if the carbon resistor

connected across the arm CD has the coloiur sequence red, red and orange, as shown in the figure.

If now the resistance of the arms BC and CD are interchanged, to obtain the balance conduction,

another carbon resistor is connected in place of R. What would now be sequence of colour bands of the

carbon resistor?
