Two stationary point charges of +60.0 uC and +50.0 uC exert a repulsive force

Physics
1 answer:
joja [24]3 years ago

Answer:

The value is r =  0.39279 \ m

Explanation:

From the question we are told that

     The first point charge is q_1 = 60.0 \mu C  =  60  *10^{-6} \ C

      The second point charge is  q_2 = 50 \mu C  =  50 *10^{-6} \  C

     The repulsive force exerted is  F  =  175 \  N

Generally the repulsive force  exerted is mathematically represented as

     F =  \frac{k * q_1 * q_2 }{r^2}

Here k is the coulomb constant with a value  k  = 9*10^{9}\ kg\cdot m^3\cdot s^{-4} \cdot A^{-2}.

So

       r =  \sqrt{\frac{ k *  q_1 * q_2 }{F} }

=>    r =  \sqrt{\frac{ 9*10^9 * 60 *10^{-6} * 50 *10^{-6}}{175} }

=>    r =  0.39279 \ m

12. An example of an atom that has no charge is one that has A. 3 protons, 1 electron, and 3 neutrons. B. 3 protons, 2 electrons
andreyandreev [35.5K]
_____________________________

[D. 2 protons, 2 electrons, and 1 neutron.]

As we know that, protons are embedded in the nucleus with neutron having no charge. So, nucleus has positive charge. Electrons are revolved around the nucleus of the atom. Proton has positive charge and electron has negative charge.

Number of proton = Number of electron.

Hence, both 2 protons and 2 electrons make the atom electrically neutral. So, the net charge of atom is 0. Neutron are the subatomic particle which has only mass.

A given mass of air has a volume of 6.00 L at 101 kPa. At constant temperature, the pressure is decreased to 25.0 kPa. Calculate
Sidana [21]

Answer:

24.24L

Explanation:

According to Boyle's law which states that "the volume of a given mass of gas at constant temperature is inversely proportional to its pressure". Mathematically, P = k/V where;

P is the pressure

V is the volume

k is the proportionality constant

PV = k

P1V1 = P2V2

P1 and P2 are initial and final pressure respectively

V1 and V2 are the initial and final volume respectively

Given P1 = 101kPa V1 = 6.0L, P2 = 25kPa V2 = ?

From the formula;

V2 = P1V1/P2

V2 = 101×6/25

V2 = 24.24L

The final volume for the gas is 24.24L

Heat is always transferred through the movement of matter in the convection mode of heat transmission.

<h3>What is heat transfer ?</h3>

Heat transfer is the movement of heat from one solid or liquid item to another. Always, heat moves from one body with a greater temperature to one with a lower temperature. To put it another way, heat always transfers from a hotter body to a cooler body.

  • Heat energy is transferred through the mechanism of conduction when nearby atoms or molecules collide. In solids and liquids, where particles are more closely spaced, conduction happens more easily than in gases, where particles are more widely spaced.

  • Here we can say that heat is transfer when there is movement between two books and hence there is change in temperature.

A ball on a string makes 25.0 revolutions in 9.37 s, in a circle radius 0.450 m. What is it’s velocity?
Sauron [17]

The velocity of the ball is 12.5 m/s

Explanation:

The velocity of the ball is given by the ratio between the distance covered by the ball and the time taken:

v=\frac{d}{t}

First, we calculate the distance covered. We know that the radius of the circle is

r = 0.450 m

And the length of the circumference is

L=2\pi r = 2\pi(0.750)=4.7 m

The ball makes 25.0 revolutions, so a total distance of

d=(25.0)L=(25.0)(4.7)=117.5 m

In a time of

t = 9.37 s

So, its velocity is

v=\frac{117.5}{9.37}=12.5 m/s
