How does the electric force vary with distance

1 answer:

3 0

The size of the force varies inversely as the square of the distance between the two charges. Therefore, if the distance between the two charges is doubled, the attraction or repulsion becomes weaker, decreasing to one-fourth of the original value.

. An object’s resistance to change in motion is dependent solely on what quantity?

Tomtit [17]

It is dependent upon the object's mass. The greater the mass of the object greater will be the inertia of the object, and hence it's resistance to change in motion as well.

A body moves in circle cover half of revolution in 10 sec its linear distance became 10m along circumference of circle than its

stiks02 [169]

The centripetal acceleration is $0.63 m/s^2$

Explanation:

The centripetal acceleration for an object in circular motion is given by

$a=\frac{v^2}{r}$

where

v is the linear speed

r is the radius of the circle

The body in the problem cover half of revolution in

t = 10 s

And the corresponding linear distance covered is

L = 10 m

which corresponds to half of the circumference, so

$L=2\pi r$

From this equation we find the radius of the circle:

$r=\frac{L}{2\pi}=\frac{10}{2\pi}=1.59 m$ [m]

While the linear speed is:

$v=\frac{L}{t}=\frac{10}{10}=1 m/s$

Therefore, the centripetal acceleration is

$a=\frac{1^2}{1.59}=0.63 m/s^2$

in this problem assume that the batteries have zero internal resistance. The currents are flowing in the direction indicated by

Leya [2.2K]

Answer:

1.2 Amps

Explanation:

<em>The question is incomplete, however, according to Ohm's law the current through a conductor between two points is directly proportional to the voltage across the two points.</em>

Given Data

Voltage= 4.4V

Resistance= 5.2 Ohms

V=IR---------------Ohms law

I= V/R

I= 5.2/4.4

I= 1.18

I= 1.2 Amps

Hence the current is 1.2 Amps
