The time between two new Moon phases or two full Moon phases is 29.5 days. ... The difference of 29.5 and 27.3 is that while the Moon is orbiting the Earth, the Earth is moving along in its orbit so it takes longer for the Moon to reach the same position relative to the Sun.

Answer:

[tex]q=6.45\ \mu C[/tex]

Explanation:

Given that,

The electrical force, F = 1.5 N

The distance between Darth Vader and Luke Skywalker, d = 0.5 m

We need to find the charge on each ship. The formula for the electric force is given by :

[tex]F=\dfrac{kq^2}{r^2}\\\\q=\sqrt{\dfrac{Fr^2}{k}} \\\\q=\sqrt{\dfrac{1.5\times 0.5^2}{9\times 10^9}} \\\\q=6.45\ \mu C[/tex]

So, the charge on each ship is equal to [tex]6.45\ \mu C[/tex].

Answer:

The combined velocity of Sally and the sled is 1.688 meters per second.

Explanation:

Let suppose that Sally collides inelasticly, meaning that final velocity of Sally-sled system can be determined solely by Principle of Momentum Conservation:

[tex]m_{S}\cdot v_{S, o} + m_{s}\cdot v_{s,o} = (m_{S}+m_{s})\cdot v[/tex] (1)

Where:

[tex]m_{S}[/tex] - Mass of Sally, measured in kilograms.

[tex]m_{s}[/tex] - Mass of the sled, measured in kilograms.

[tex]v_{S,o}[/tex] - Initial velocity of Sally, measured in meters per second.

[tex]v_{s,o}[/tex] - Initial velocity of the sled, measured in meters per second.

[tex]v[/tex] - Final velocity of the Sally-sled system, measured in meters per second.

If we know that [tex]m_{S} = 54\,kg[/tex], [tex]m_{s} = 10\,kg[/tex], [tex]v_{S,o} = 2\,\frac{m}{s}[/tex] and [tex]v_{s,o} = 0\,\frac{m}{s}[/tex], then the final velocity of the system is:

[tex]v = \frac{m_{S}\cdot v_{S,o}+m_{s}\cdot v_{s,o}}{m_{S}+m_{s}}[/tex]

[tex]v = 1.688\,\frac{m}{s}[/tex]

The combined velocity of Sally and the sled is 1.688 meters per second.

A roller coaster is released from the top of a track that is 125 m high. Find the roller coaster speed when it reaches ground level. 75. A 1500 kg car, moving at a speed of 20 m/s comes to a halt. How much work was done .

The roller coaster speed when it reaches to ground level is 15.65 m/sec

Given-

Roller coaster is released at a height of 125 meters.

It is known that, square of the final velocity [tex]v[/tex] of the body is equal to the sum of the square of initial velocity [tex]v_{10}[/tex] and the product of the twice of acceleration [tex]a[/tex] and displacement [tex]d[/tex]. It can be written as,

[tex]v^{2} =v_{0}^2+2ad[/tex]

Roller coaster released from rest therefore initial velocity is zero.

[tex]v^{2} =0+2ad[/tex]

[tex]v^{2} =2ad[/tex]

Roller coaster will fall towards the ground with an acceleration equal to gravity g and height of 125 m. therefore,

[tex]v^{2} =2\times g\times 125[/tex]

[tex]v^{2} =2\times 9.8\times 125[/tex]

[tex]v^{2} =2450[/tex]

[tex]v=15.65[/tex]

Hence, the roller coaster speed when it reaches to ground level is 15.65 m/sec.

Answer:

a change of position in relation to another object.

Explanation:

Motion can be defined as a change in the location (position) of a physical object or body with respect to a reference point.

This ultimately implies that, motion would occur as a result of a change in location (position) of an object with respect to a reference point or frame of reference i.e where it was standing before the effect of an external force.

A reference point refers to a location or physical object from which the motion (movement) of another physical object or body can be determined.

Mathematically, the motion of an object is described in terms of acceleration, time, distance, speed, velocity, displacement, position, etc.

Hence, motion is a change of position in relation to another object.

Answer:

1 =The kinetic theory of gases is a simple, historically significant model of the thermodynamic behavior of gases, with which many principal concepts of thermodynamics were established. The model describes a gas as a large number of identical submicroscopic particles, all of which are in constant, rapid, random motion.

2 =When this bimetallic strip is heated, the brass expands more than the steel and the strip curves with the brass on the outside. If the strip is cooled, it curves with the steel on the outside.

3 =Bimetal strips are also used in time-delay relays, gas oven safety valves, thermal flashers for older turn signal lamps, and fluorescent lamp starters.

Explanation:

A planet's orbital speed changes, depending on how far it is from the Sun. The closer a planet is to the Sun, the stronger the Sun's gravitational pull on it, and the faster the planet moves. The farther it is from the Sun, the weaker the Sun's gravitational pull, and the slower it moves in its orbit.

Answer:

The force used by the helmet in stopping the ball  is 5,333.33 N.

Explanation:

Given;

force applied to ball, F₁ = 2,000 N

duration of force impact, t₁ = 0.8 s

duration of the helmet impact, t₂ = 0.3 s

Let the force used by the helmet in stopping the ball be given as F₂.

Apply the principle of conservation of linear momentum to determine F₂.

F₁t₁ = F₂t₂

F₂ = (F₁t₁) / (t₂)

F₂ = 5,333.33 N

Therefore, the force used by the helmet in stopping the ball  is 5,333.33 N.
