Answer:

Force between two charges is 10.8 N

both charges are positive nature charge so they both repel each other and hence q2 will move away from charge q1

Explanation:

As we know that the force between two charge particles is given by Coulomb's law of electrostatics

So we will say it as

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

here we know that

q_1 = 6\mu C

q_2 = 2\mu C

d = 0.1 m

F = \frac{8.99 \times 10^9(6 \mu C)(2\mu C)}{0.1^2}

F = 10.8 N

Since both charges are positive nature charge so they both repel each other and hence q2 will move away from charge q1

A stone is dropped at t = 0. A second stone, with twice the mass of the first, is dropped from the same point at t = 181 ms. How
lara [203]

Answer:

the center of mass is 316,670m bellow the release point.

Explanation:

First, we must find the distance at which the objects are in time t = 360s

We will use the formula for vertical distance in free fall

h=v_{0}t+\frac{1}{2} gt^2

v_{0} is the initial velocity, is 0 for both stones since they were just dropped.

g is acceleration of gravity and t is time (g=9.81m/s^2)

At t=360s the first stone has been falling for the entire 360 seconds, its position h1 is:

h_{1}=\frac{1}{2} (9.82m/s^2)(360s^2)=635,688m

And at 360 seconds the second stone has been fallin fort= 360s -181 s = 179s, so its position h2 is:

h_{2}=\frac{1}{2} (9.81m/s^2)(179)^2=157,161.1m

And finally using the equation for the center of mass:

CM=\frac{m_{1}h_{1}+m_{2}h_{2}}{m_{1}+m_{2}}

We know that the mass of the second stone is twice the mass of the first stone so:

m_{1}=m\\m_{2}=2m

replacing these values in the equation for the center of mass

CM=\frac{mh_{1}+2mh_{2}}{m+2m}

CM=\frac{m(h_{1}+2h_{2})}{3m}=\frac{h_{1}+2h_{2}}{3}

Finally, replacing the values we found fot h1 and h2:

CM=\frac{635,688m+2(157,161.1m)}{3}=316,670m

the center of mass is 316,670m bellow the release point.

Which force diagram accurately represents a satellite in orbit around Earth?
Anit [1.1K]

Answer:

First choice

Explanation:

A satellite in orbit around Earth experiences only one force: the gravitational attraction exerted by the Earth on it. This force is labelled with F_g. In space, there are no other forces acting on the satellite.

The force of gravity acts as centripetal force, "pulling" the satellite towards the centre of its circular orbit. The inertia of the satellite (which has an initial velocity) tends to keep it moving straight, so the combination of these two effects (inertia and force of gravity) results into the circular motion of the satellite.

iren [92.7K]

Answer:

No, the magnitude of the magnetic field won't change.

Explanation:

The magnetic field produced by a wire with a constant current is circular and its flow is given by the right-hand rule. Since this field is circular with center on the wire the magnitude of the magnetic field around the wire will be given by B = [(\mi_0)*I]/(2\pi*r) where (\mi_0) is a constant, I is the current that goes through the conductor and r is the distance from the wire. If the field sensor will move around the wire with a fixed radius the distance from the wire won't change so the magnitude of the field won't change.

What is a convenient way to show how a fixed quantity is broken down into parts?
Marysya12 [62]
A convenient way to show how a fixed quantity is broken down into parts is by using a circle graph.

A circle graph shows different fixed parts in relation to the whole. All of the parts make up the whole.
