The people in the ship will see light travelling toward them at speed of light.

<u>Explanation:</u>

As the spaceship is moving away from the space station with one half speed of light. The light travelling from the space station with velocity c which is also termed as speed of light will be moving relative to the people in spaceship. So the relative velocities can be found as

                 u^{\prime}=\frac{u-v}{1-\frac{u v}{c^{2}}}

In this case, u’ is the speed of light seen by the people in spaceship and u is the velocity of light while v is the velocity of moving spaceship.So u =c and v = \frac{c}{2}. Then

                u^{\prime}=\frac{c-c / 2}{1-\frac{c \times c / 2}{c^{2}}}=\frac{c / 2}{1-\frac{c^{2}}{2 c^{2}}}=\frac{c / 2}{1 / 2}=c

Thus, the light travelling towards the people in the ship will view that light with the speed of light itself.

Yuliya22 [10]

Answer:

B: precipitation seeping through pores and cracks in the ground

Explanation:

Man made wells aren't the main source because their isn't enough of them and morning dew doesn't go in to the ground in one main source.

Why do electric field lines explain why like charges repel and opposite charges attract?
vivado [14]

It can be explained as follows: consider the field produced by a positive charge. If we place a positive test charge in this a field, then this charge would move away from the central charge (because like charges repel), while if we place a negative test charge in this field, this charge would move towards the central charge (because opposite charges repel)

Explanation:

Electric fields are vector fields, and they are represented using field lines.

The field lines give indications on both the magnitude and the direction of the electric field. In fact:

  • The magnitude of the field can be inferred from the spacing between the lines: the closer the lines are, the stronger the field, while for a weaker field the lines are more spread apart
  • The direction of the field is given by the direction of the field lines

In particular, by convention the direction of the field lines represent the direction of the force that a positive test charge would feel when immersed in that field: this means that a positive test charge would accelerate in the direction of the field lines, while a negative test charge would accelerate in the direction opposite to the field lines.

This is in agreement with the fact that like charges repel and opposite charges attract. In fact, the lines of the electric field produced by a single-point positive charge point away from the positive charge: if we place a positive test charge in this field, then this charge would move away from the central charge (because like charges repel), while if we place a negative test charge in this field, this charge would move towards the central charge (because opposite charges repel).

Why is gasoline so flammable
Karo-lina-s [1.5K]
Flammable and combustible liquids themselves do not burn. It is the mixture of their vapours and air that burns. Gasoline, with a flashpoint of -40°C (-40°F), is a flammable liquid. Even at temperatures as low as -40°C (-40°F), it gives off enough vapour to form a burnable mixture in air.

The masses of the Moon and Earth are 7.35 x 1022 kg and 5.97 x 1024 kg, respectively. The strength of the gravitational force be
bixtya [17]

Answer:

Distance between centre of Earth and centre of Moon is 3.85 x 10⁸ m

Explanation:

The attractive force experienced by two mass objects is known as Gravitational force.

The gravitational force is determine by the relation:

F=\frac{Gm_{1} m_{2} }{d^{2} }      ....(1)

According to the problem,

Mass of Moon, m₁ = 7.35 x 10²² kg

Mass of Earth, m₂ = 5.97 x 10²⁴ kg

Gravitational force experienced by them, F = 1.98 x 10²⁰ N

Universal gravitational constant, G = 6.67 x 10⁻¹¹ Nm²kg⁻²

Substitute these values in equation (1).

1.98\times10^{20} =\frac{6.67\times10^{-11}\times7.35\times10^{22}\times5.97\times10^{24} }{d^{2} }

d^{2}=\frac{2.93\times10^{37}}{1.98\times10^{20}}

d=\sqrt{1.48\times10^{17}}

d = 3.85 x 10⁸ m
