Answer: The greater an object's mass, the more gravitational force it exerts.

Explanation: So, to begin answering your question, Earth has a greater gravitational pull than the moon simply because the Earth is more massive. Sorry if I get this wrong. I am in 5th grade! ♥

The gravitational attraction between the Sun and Earth is stronger than the attraction between the Sun and the Moon, principally because of the Sun's greater mass and greater distance from Earth.

An object's mass affects how much gravitational pull it exerts. Both the Earth and the Moon are much less massive than the Sun. Approximately  330,000 times more massive than the Earth, and roughly 27 million times more massive than the Moon, is the Sun. Because of the Sun's greater mass, its gravitational pull is thus much stronger.

The strength of the gravitational force between two objects is greatly influenced by their distance from one another. The Sun and Earth are separated from one another by a far smaller distance than the Sun and Moon. The Sun is located roughly 150 million kilometers from Earth, while the Moon is located roughly 384,400 kilometers from the Sun on average. The inverse square law asserts that the gravitational force decreases with increasing distance, and that it is only one-fourth as strong when two objects are twice as far apart.

Hence, the gravitational force between the sun and earth is larger than the sun and the moon due the mass of the sun and earth is greater than the moon and sun. The distance between the sun and the earth is comparatively smaller than the distance between the sun and the moon.

Sliding friction is friction that acts on objects when they are sliding over a surface. Sliding friction is weaker than static friction. That's why it's easier to slide a piece of furniture over the floor after you start it moving than it is to get it moving in the first place.

No...

Explanation:

I think this may be a trick question... so from my reasonable logic, I'm gonna say no because more often then not they are attached to the wall with nails/screws. Or they are hanging.

So they could come off. Also if someone was desperate, they could always grab a chainsaw and force it off of the wall. Not a great idea though, then the wall would be broken!! Most likely the clock too!

Answer:

2.4m/s²

Explanation:

Given parameters:

Initial velocity  = 0m/s

Time 25s

Final velocity  = 60m/s

Unknown:

Acceleration  = ?

Solution:

Acceleration is the rate of change of displacement

      Acceleration  = [tex]\frac{Final velocity - Initial velocity}{time}[/tex]

    Acceleration  = [tex]\frac{60 - 0}{25}[/tex]    = 2.4m/s³

Answer:

[tex]K=120[/tex]

Explanation:

From the question we are told that

Length of spring   [tex]l_1=0.5m[/tex]

Length of stretched [tex]l_s=1m[/tex]

Potential energy of spring [tex]E=15J[/tex]

Generally equation for energy stored is mathematically given as

[tex]U=1/2K \triangle x^2[/tex]

[tex]K=\frac{2U}{\triangle x^2}[/tex]

[tex]K=\frac{2*15}{ 0.5^2}[/tex]

Therefore value of the spring constant in N/m? is given as

[tex]K=120[/tex]

The value of the spring constant is 120 N/m.

The spring constant of the spring is calculated by applying the principle of conservation of energy as follows;

[tex]\frac{1}{2} k \Delta x = U[/tex]

Where;

The value of the spring constant is calculated as follows;

[tex]k = \frac{2U}{\Delta x} \\\\k = \frac{2\times 15}{0.5^2}\\\\k = 120 \ N/m[/tex]

The International Space Station was  built from separate parts sent to space.

A sizable spacecraft in orbit orbiting the Earth is called the International Space Station. Crews of astronauts and cosmonauts reside there as a home. The space station serves as an exceptional science lab. The space station was created and used by international cooperation.

The components of the space station were put together by astronauts while they were in space. It travels around 250 miles above Earth's surface on its typical orbit. It has a speed of 17,500 mph. It therefore orbits the planet every 90 minutes. The space station is being used by NASA to learn more about surviving and operating in space. These discoveries will enable sending more people into space than ever before.

For the entire space station, there is no set ownership stake. Instead, each partner should maintain authority and control over the elements it registers and over employees in or on the Space Station who are its nationals, according to Article 5 of the IGA. As a result, only one partner holds sole control of each ISS module. However, the contracts for using the space station's amenities are more intricate.

Answer:

500m

Explanation:

100x5=500

then add the m

Answer:

6m/s²

Explanation:

Given parameters:

Initial velocity  = 35m/s

Final velocity  = 65m/s

Time taken  = 5s

Unknown:

Acceleration = ?

Solution:

Acceleration is the rate of change of velocity with time taken;

   Acceleration  = [tex]\frac{Final velocity - Initial velocity }{time}[/tex]  

So;

 Acceleration   = [tex]\frac{65 - 35}{5}[/tex]    = 6m/s²

Answer:

The wavelength of the waves traveling along the string is 12 meters.

What is a Wavelength?

Given:

Waves propagate along the stretched string at speed = 8.0 m/s

The end of the string vibrates up and down once every 1.5 s.

∴ Time = 1.5 s

We have to find the wavelength of the waves.

We know,

⇒ Time = 1/frequency

⇒ 1/frequency = 1.5

Now

⇒ speed = frequency × wavelength

⇒ wavelength = speed / frequency

⇒ wavelength = 8 × 1.5

⇒ wavelength = 12 m

Therefore, the wavelength of the waves traveling along the string with given speed is 12 m.

C. The diameter of a wire

Explanation:

A micrometer screw gauge is a device used for the measurement of small dimensions which may not be measured accurately by the use of a vernier caliper, e.g diameter of a thin wire. it has a high degree of accuracy.

From the given option in the question, the measurement that can be made using a micrometer screw gauge is the diameter of a wire

The measurement that should be used via using the micrometer screw gauge is option  C. The diameter of a wire

It is the device that should be used for measuring the small dimension that should not be measured in an accurate way via the use of an vernier caliper. Also, it contains the high accuracy degree. So the measurement should not be done by turning effect, microwaves wavelength, tyre air pressure

Therefore, the option c is correct.

The moon its self does not generate life.

Explanation:

Moon phases are determined by the relative positions of the Moon, Earth, and Sun.  Instead, the Moon's phase depends only on its position relative to Earth and the Sun. The Moon doesn't make its own light, it just reflects the Sun's light as all the planets do. The Sun always illuminates one half of the Moon.

Given parameters:

Mass of freight train  = 270700kg

Acceleration = 40m/s²

Unknown:

Force acting on the train = ?

Solution:

From Newton's second law of motion, we know that:

       Force  = mass x acceleration

So;

        Force  = 270700 x 40   = 1.08 x 10⁷N

Answer:

ALWAYS ( in all cases and at all times)

Explanation:

From Newton's 3rd Law of motion which states that every action that occurs (force) there will be equal as well as opposite reaction. Therefore as the man is pushing the chair exerting 50N force, the chair also is is exerting equal force as well as opposite force on him as he is pushing it

That's the Ampere.

1 Ampere = 1 Coulomb of charge per second.
