Answer:

d=0.8 m : Distance between the charges

Explanation:

To solve this problem we apply Coulomb's law:

Two point charges (q₁, q₂) separated by a distance (d) exert a mutual force (F) whose magnitude is determined by the following formula:

F=K*q₁*q₂/d² Formula (1)

F: Electric force in Newtons (N)

K : Coulomb constant  in N*m²/C²

q₁,q₂:Charges in Coulombs (C)

d: distance between the charges in meters(m)

Equivalence

1uC= 10⁻⁶C

Data

F=0.66 N

K=8.99x10⁹N*m²/C²

q₁ = +8.4 uC=+8.4 *10⁻⁶C

q₂= +5.6 uC= +5.6 *10⁻⁶C

Calculation of the distance (d) separating the charges

We replace data in the equation (1):

0.66=\frac{8.99*10^{9}*8.4*10^{-6} *5.6*10^{-6}  }{d^{2} }

d^{2} =\frac{422.89*10^{-3} }{0.66}

d²=640.74*10⁻³

d=\sqrt{640.74*10^{-3} }

d=0.8 m

Answer:

it is separated by 80 cm distance

Explanation:

As per Coulombs law we know that force between two point charges is given by

F = \frac{kq_1q_2}{r^2}

here we know that

q_1 = +8.4\mu C

q_2 = +5.6 \mu C

force between two charges is given as

F = 0.66 N

now we have

F = \frac{kq_1q_2}{r^2}

0.66 = \frac{(9\times 10^9)(8.4 \mu C)(5.6 \mu C)}{r^2}

r = 0.8 m

so it is separated by 80 cm distance

What is the kinetic energy of an object that has a mass of 12 kg and moves with a velocity of 10 m/s
WITCHER [35]

Answer:

600 J

Explanation:

The formula to find the kinetic energy of an object is \frac{1}{2}mV^2

  • m = mass in kg
  • V = velocity in m/s
  • KE is measured in Joules just as all other forms of energy.

Now, let's plug in the variables we're given and simplify.

  • \frac{1}{2}(12)(10)^2
  • \frac{1}{2}(12)(100)
  • (6)(100)
  • (600)

Thus, the answer is 600 Joules.

Where is heat transferred by radiation in a lava lamp
GuDViN [60]

Answer:

Explanation:

A lava lamp consists of oil, and wax in a glass, and a heat source (a light bulb) placed underneath the glass. When the lamp is turned on the bulb gets hot. As the bulb heats up some of the heat from the bulb is transferred to the glass by radiation.

As the distance from a charged particle, "q", increases, what happens to the electric potential?
mr Goodwill [35]

As the distance from a charged particle, "q", increases, the electric potential decreases.

<h3>Electric potential between particles</h3>

The electric potential between particles is the work done in moving a unit charge from infinity to a certain point against the electrical resistance of the field.

V = Kq/r

where;

  • K is Coulomb's constant
  • q is the magnitude of the charge
  • r is the distance between the charges

Thus, from the formula above, as the distance from a charged particle, "q", increases, the electric potential decreases.

A snowboarder on a slope starts from rest and reaches a speed of 4.2 m/s after 7.3 s
Yakvenalex [24]

The car's acceleration will be 0.575 m/s².The unit of acceleration is m/sec².

<h3>What is acceleration?</h3>

The rate of velocity change concerning time is known as acceleration.

Given data;

Initial velocity, u= 0 m/s

Final velocity, v= 4.2 m/s

Time elapsed, t = 7.3 seconds.

To find ;

Acceleration, a

The acceleration when the change in velocity is observed by the formula as:

a= (v-u)/(t)

Substitute the given values:

a= (4.2-0)/(7.3)

a=(4.2)/(7.3)

a= 0.575 m/s²

Hence, the car's acceleration will be 0.575 m/s².
