mamaluj [8]

Strange as it may seem, the object would keep moving, in a straight line and at the same speed, until it came near another object. Its momentum and kinetic energy would never change. It might continue like that for a billion years or more.

Have a look at Newton's first law of motion.

QveST [7]

Answer:

To create an electric potential difference between the ends of the conductor.

Explanation:

For current to flow, there must exist an electric potential difference between the ends of the conductor. This PD is provided by the electromotive force stored within the battery. Unless there is a connection between the terminals no PD will exist between the terminals.

Ymorist [56]

If the cross-section of a wire of fixed length is doubled, the resistance of that wire change into doubled.We know that the total length of the wires will affect the amount of resistance. The longer the wire, the more resistance that there will be so the answer is doubled.

Consider identical spherical conducting space ships in deep space where gravitational fields from other bodies are negligible co

Illusion [34]

Answer:

q = 8.61 10⁻¹¹ m

charge does not depend on the distance between the two ships.

it is a very small charge value so it should be easy to create in each one

Explanation:

In this exercise we have two forces in balance: the electric force and the gravitational force

F_e -F_g = 0

F_e = F_g

Since the gravitational force is always attractive, the electric force must be repulsive, which implies that the electric charge in the two ships must be of the same sign.

Let's write Coulomb's law and gravitational attraction

$k \frac{q_1q_2}{r^2} = G \frac{m_1m_2}{r^2}$

In the exercise, indicate that the two ships are identical, therefore the masses of the ships are the same and we will place the same charge on each one.

k q² = G m²

q = $\sqrt{ \frac{G}{k} }$ m

we substitute

q = $\sqrt{ \frac{ 6.67 \ 10^{-11}}{8.99 \ 10^{9}} }$ m

q = $\sqrt{0.7419 \ 10^{-20}}$ m

q = 0.861 10⁻¹⁰ m

q = 8.61 10⁻¹¹ m

This amount of charge does not depend on the distance between the two ships.

It is also proportional to the mass of the ships with the proportionality factor found.

Suppose the ships have a mass of m = 1000 kg, let's find the cargo

q = 8.61 10⁻¹¹ 10³

q = 8.61 10⁻⁸ C

this is a very small charge value so it should be easy to create in each one
