You are looking to find gravitational energy, the formula for that is (height)(weight)(acceleration due to gravity). In your case I️t will be (3)(2)(9.8)= 58.8 Joules

A certain capacitor, in series with a resistor, is being charged. At the end of 10 ms its charge is half the final value. The ti

vichka [17]

To solve this problem we will apply the expression of charge per unit of time in a capacitor with a given resistance. Mathematically said expression is given as

$q(t) = e^{-\frac{t}{(R*C)}}$

Here,

q = Charge

t = Time

R = Resistance

C = Capacitance

When the charge reach its half value it has passed 10ms, then the equation is,

$\frac{1}{2}*q_{final} = e^{-\frac{0.01}{(R*C)}}$

$Ln(\frac{1}{2}) = -\frac{0.01}{RC}$

$- RC = \frac{0.01}{Ln(1/2)}$

$RC = 0.014s$

We know that RC is equal to the time constant, then

$T = RC = 0.014s = 14ms$

Therefore the time constant for the process is about 14ms

How much work is done in lifting a 50-N box at a height of 1.5M

vaieri [72.5K]

Work done = M x g x h

M = Mass of the body in Kg

g = Acceleration due to gravity

h - height of displacement

Work done = (M x g) x h

= 50 N x 1.5 m

= 75 J
