What is the energy stored, in units of nanoJoules, on a 14.8 nF capacitor when the voltage applied across the capacitor is 7.2 V

AVprozaik [17]

Answer:

383.6 nJ

Explanation:

The energy stored in a capacitor is given by the formula:

$E=\frac{1}{2}CV^2$

where

C is the capacitance

V is the voltage applied

In this problem, we have

C = 14.8 nF is the capacitance of the capacitor

V = 7.2 V is the voltage

Substituting into the equation, we find:

$E=\frac{1}{2}(14.8 nF)(7.2 V)^2=383.6 nJ$

A simple accelerometer is constructed inside a car by suspending an object of mass m from a string of length L that is tied to t

Fittoniya [83]

Answer:

Part a)

$\theta = tan^{-1}\frac{a}{g}$

so here the angle made by the string is independent of the mass

Part b)

$a = 4.16 m/s^2$

Explanation:

Part a)

Let the string makes some angle with the vertical so we have force equation given as

$Tcos\theta = mg$

$T sin\theta = ma$

so we will have

$tan\theta = \frac{ma}{mg}$

$\theta = tan^{-1}\frac{a}{g}$

so here the angle made by the string is independent of the mass

Part b)

Now from above equation if we know that angle made by the string is

$\theta = 23 degree$

so we will have

$tan23 = \frac{a}{g}$

$a = g tan23$

$a = 9.81(tan23)$

$a = 4.16 m/s^2$
