Answer:

Electric potential energy, or Electrostatic potential energy, is a potential energy (measured in joules) that results from conservative Coulomb forces and is associated with the configuration of a particular set of point charges within a defined system.

If a 4kg Bird is pushed by the window with a force of 60 N how fast is the bird accelerate?
LiRa [457]
  • Force=60N
  • Mass=4kg

\\ \ast\sf\hookrightarrow Force=Mass\times Acceleration

\\ \ast\sf\hookrightarrow Acceleration=\dfrac{Force}{Mass}

\\ \ast\sf\hookrightarrow Acceleration=\dfrac{60}{4}

\\ \ast\sf\hookrightarrow Acceleration=15m/s^2

Find the average velocity of the object from point B to C.
ExtremeBDS [4]
The average velocity of the object in moving from point-B to point-C is

                 (the straight-line distance and direction from point-B to point-C)
divided by
                 (the time the object takes to make the trip) .

A baseball is hit so that it travels straight upward after being struck by the bat. A fan observes that it takes 3.00 s for the
Vladimir [108]

Answer:

Initial velocity = 29.43m/s b) Height it reaches = 44.145 m

Explanation:

Using the first equation of motion we have

v=u+at

here

v is the final velocity

u is the initial velocity

a is the acceleration of the object

t is time

When the ball reaches it's highest point it's velocity will become 0 as it will travel no further

Also the acceleration in our case is acceleration due to gravity (-9.8m/s^{2}) as the ball moves in it's influence alone with '-' indicating downward direction

Thus applying the values we get

0=u-(9.81)m/s^{2}\times 3\\\\u=19.43m/s

b)

By 3rd equation of motion we have

v^{2}-u^{2}=2gs

here s is the distance covered

Applying the value of u that we calculated we get

s=\frac{-u^{2}}{2g}\\\\s=\frac{-29.43^{2}}{-2\times 9.81}\\\\s=44.145m

If two metal balls each have a charge of -10^-6 C and the repulsive force between them is 1 N, how far apart are they? (Coulomb'
Vitek1552 [10]

Answer:

The distance between the charges is 9.5 cm

(c) is correct option

Explanation:

Given that,

Charge q= 10^{-6}\ C

Force F = 1 N

We need to calculate the distance between the charges

Using Coulomb's formula

F = \dfrac{kq_{1}q_{2}}{r^2}

Where, q = charge

r = distance

F = force

Put the value into the formula

1=\dfrac{9.0\times10^{9}\times(-10^{-6})^2}{r^2}

r=\sqrt{9\times10^{9}\times(-10^{-6})^2}

r=0.095\ m

r= 9.5\ cm

Hence, The distance between the charges is 9.5 cm
