B. The electric potential at the given point from the proton is 2.7 x 10¹ volts

<h3>Electric potential of the proton</h3>

The electric potential of the proton is calculated as follows;

V = kq/r

where;

  • k is Coulomb's constant
  • q is charge
  • r is distance

V = (9 x 10⁹ x 1.6 x 10⁻¹⁹)/(5.3 x 10⁻¹¹)

V = 27.2 volts

V = 2.7 x 10¹ volts

The answer would be A. As the bat is swung, it gains kinetic energy. But once it hits the ball, it loses, or transfers, it’s kinetic energy to the ball.

If Earth's mass was cut in half, what would happen to your mass? Group of answer choices
Alex777 [14]

Answer:

nothing, mass is not affected by gravitational force

Explanation:

Weight is the gravitational force a planet exerts on a mass on the surface.

It is the product of the mass of an object with the gravitational acceleration that the planet produces.

The weight is the gravitational force

W=mg

where,

m = Mass of the object

g = Acceleration due to gravity = 9.81 m/s²

Mass is the property that matter has which opposes the force being applied to it. It is intrinsic to the object itself and does not change according to the gravitational force. But, the weight changes.

A simple pendulum is made from a 0.54-m-long string and a small ball attached to its free end. The ball is pulled to one side th
Serga [27]

Answer:

0.37sec

Explanation:

Period of oscillation of a simple pendulum of length L is:

T = 2 π × √ (L /g)

L=length of string 0.54m

g=acceleration due to gravity

T-period

T = 2 x 3.14 x √[0.54/9.8]

T = 1.47sec

An oscillating pendulum, or anything else in nature that involves "simple harmonic" (sinusoidal) motion, spends 1/4 of its period going from zero speed to maximum speed, and another 1/4 going from maximum speed to zero speed again, etc. After four quarter-periods it is back where it started.

The ball will first have V(max) at T/4,

=>V(max) = 1.47/4 = 0.37 sec

A gas has a volume of 60dm³ when it is under a pressure of 30kpa. Calculate it's volume when pressure changes
vesna_86 [32]

Explanation:

Given that,

Initial volume = 60dm³

Initial pressure = 30 kPa

We need to find the new volume when pressure changes to 40 kPa (say).

We know that the mathematical relation between volume and pressure is given by :

\dfrac{P_1}{P_2}=\dfrac{V_2}{V_1}

Put all the values,

V_2=\dfrac{P_1V_1}{P_2}\\\\V_2=\dfrac{30\times 60}{40}\\\\V_2=45\ dm^3

So, when pressure of the gas increases, its volume get decreased.
