Lucy boards a crowded bus as it sits in the station. There are no available seats, so Lucy stands in the center aisle next to a

support pole. As the bus starts moving forward and picks up speed, Lucy holds the pole tightly to avoid falling over backward. While the bus is speeding up, what is the direction of the total force (if any) on Lucy?
Is it forward? baclwards? or the total force is zero?

As the bus drives down a straight road at a constant speed, Lucy has no trouble keeping her balance. During this time, what is the direction of the total force (if any) on Lucy?

Is it forward? baclwards? or the total force is zero?

The bus comes to a sudden stop at a red light, and Lucy grips the pole tightly to avoid falling over forward. During this time, what is the direction of the total force (if any) on Lucy?

Is it forward? baclwards? or the total force is zero?

Why are fuse wires not provided in an electric circute containing an electric cell
Basile [38]

Hey there,

Electric cells we use usually carry limited voltage. Here's an example: 1.5V. Really, there is no chance of any shot circuit. that's why MCB and fuse wires are not used in their circuit .

A 9-μC positive point charge is located at the origin and a 6 μC positive point charge is located at x = 0.00 m, y = 1.0 m. Find
sukhopar [10]

Answer:

The coordinates of the point is (0,0.55).

Explanation:

Given that,

First charge q_{1}=9\times10^{-6}\ C at origin

Second charge q_{2}=6\times10^{-6}\ C

Second charge at point P = (0,1)

We assume that,

The net electric field between the charges is zero at mid point.

Using formula of electric field

E=\dfrac{kq}{r^2}

0=\dfrac{k\times9\times10^{-6}}{d^2}+\dfrac{k\times6\times10^{-6}}{(1-d)^2}

\dfrac{(1-d)}{d}=\sqrt{\dfrac{6}{9}}

\dfrac{1}{d}=\dfrac{\sqrt{6}}{3}+1

\dfrac{1}{d}=1.82

d=\dfrac{1}{1.82}

d=0.55\ m

Hence, The coordinates of the point is (0,0.55).
