Which of the following statements accurately describes a series circuit? Select all that apply. The flow of electrons follow the
hammer [34]

In series connections, the flow of electrons follow the same path as the current remains constant in all the elements of the circuits.

And the total resistance of the circuit increases as more resistors are added to the circuit in serial manner.

Option A and D

<u>Explanation:</u>

A circuit consists of number of passive and active devices in it. And depending upon the connections between the passive devices, the flow of current and potential drop across them will be specified.

Like if the passive devices are connected parallel to each other, the current flow through each device will vary but the voltage drop will be same. Similarly, if the passive devices are connected in series, then the current flow will be constant in the devices but the potential drop will vary.

Thus, in series connections, the flow of electrons follow the same path as the current remains constant in all the elements of the circuits. And the total resistance of the circuit increases as more resistors are added to the circuit in serial manner.

A neutron star and a black hole are 3.34 x 1012 m from each other at a certain point in their orbit. The neutron star has a mass
m_a_m_a [10]

Answer:

  F=1.65 x 10²⁶ N

Explanation:

Given that

Distance ,R= 3.34 x 10¹² m

Mass m₁= 2.78 x 10³⁰ kg

Mass ,m₂= 9.94 x 10³⁰ kg

we know that gravitational force F given as

F=G\dfrac{m_1m_2}{R^2}

G=Constant

G=6.67 x 10⁻¹¹ Nm²/kg²

Now by putting the values

F=6.67\times 10^{-11}\times \dfrac{2.78\times 10^{30}\times 9.94\times 10^{30}}{(3.34\times 10^{12})^2}\ N

F=1.65 x 10²⁶ N

Therefore the force between these two mass will be 1.65 x 10²⁶ N.
