Why does the moon go through phases?

Physics
2 answers:
givi [52]3 years ago

Answer:

The Moon has phases because it orbits Earth, which causes the portion we see illuminated to change.

Explanation:

The Moon takes 27.3 days to orbit Earth, but the lunar phase cycle (from new Moon to new Moon) is 29.5 days. ... As the Sun sets, the Moon rises with the side that faces Earth fully exposed to sunlight (5).

Answer: it has phase because it orbits and rotates causing the sunlight to hit different parts of the moon making it light up a certain way

It means mass can be converted into energy.

I. E. In a nuclear fission, we start of with a greater mass of our rectant, which then decrease due to mass being converted into the (thermal) energy released, in our reaction. Later, being used to produce electricity, for example.

Hope this helps!

2. Can you place three forces of 5g, 6g, and 12g so they are in equilibrium. Justify your answer.
Bond [772]

Answer:

We cannot place three forces of 5g, 6g, and 12g in equilibrium.

Explanation:

Equilibrium means their sum must be zero.

Here the forces are 5g, 6g, and 12g.

For number of forces to be in equilibrium the magnitude of largest vector should be less than sum of the magnitude of other vectors.

Here

        Magnitude of largest force = 12 g

        Sum of magnitudes of other forces = 5g + 6g = 11g

       Magnitude of largest force >   Sum of magnitudes of other forces

So this forces cannot form equilibrium.

We cannot place three forces of 5g, 6g, and 12g in equilibrium.

A submarine dives 185.0 m at an angle of 15.0◦ below the horizontal. What is the horizontal component of the submarine’s displac
stepan [7]

Answer:

Horizontal component, d_x=178.69\ m

Explanation:

It is given that,

Displacement of the submarine, d = 185 m

It is at an angle of 15 degrees below the horizontal. We need to find the horizontal component of the submarine's displacement. It is given by :

d_x=d\ cos\theta

Substituting the values in above equation as :

d_x=185\times \ cos(15)

d_x=178.69\ m

So, the horizontal component of the submarine’s displacement is 178.69 meters. Hence, this is the required solution.

Suppose the universe were completely empty except for one object- a solid sphere moving through space at a speed of 100km/s. wha

Straight linear path

Explanation:

If the universe were completely empty with just one object which is solid moving sphere  through the space at a speed of 100km/s, it will move along on a straight path.

An object will continue on a straight path or at rest unless acted upon by an external force. This is the first law of newton.

  • Since there is no other mass or body in the universe, it will move along in a straight line.
  • Our planet and other bodies moves in parabolic path and elliptical orbits because they are attracted by the gravitational forces of other bodies.
  • Any body with mass will attract other bodies and makes it move round it.
  • The body with the less mass will orbit in the vicinity of the larger mass.
  • But if we have just one body out there, there is no attraction from any other body, it will continue along it's straight path.
