Explanation:
are clocks permanently stuck to walls?
Answer:
It depends
Explanation:
what is this question
Answer:
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!

the gravitational force between the sun and earth is larger than sun and the moon. what do you think the reason for this is?
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.

A man is attempting to push a chair across the floor exerting a force of 50 N .When will the chair exert a force of 50 N on the man?
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

10)A car is moving from rest and attained a velocity of 80 m/s. Calculate the
acceleration of the car after 5 s?
Answer:
initial velocity (u)=0
final velocity (v)=80m/s
time(t)=5s
acceleration (a)=?
Explanation:
we have
v=u+at
80=0+a×5
5a=80
a=80/5=16m/s²
Waves propagate along a stretched string at a speed of 8.0 m/s. The end of the string vibrates up and down once every 1.5 s. What is the wavelength of the waves traveling along the string?
Answer:
So we have waves F= 1/t So F= 1/1.5= 0.66V= wavelength × F 8.0m/s= x × 0.66x=12.2The wavelength of the waves traveling along the string is 12 meters.
What is a Wavelength?
The distance between adjacent successive crests or troughs of a wave is termed as its wavelength. Wavelength is calculated in the wave's direction.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.

A freight train has a mass of 270, 700 kg and has an acceleration of 40 m/s2. How much force is acting on the train? Formula:
Answer:
1.08 x 10⁷N
Explanation:
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
Why do we see Moon phases?
Answer:
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.

A car is traveling in a race. The car went from the initial velocity of 35 m/s to the final velocity of 65 m/s in 5 seconds. What is the acceleration? 0-13 m/s2 0-6 m/s2 0.6 m/s2 O 13 m/s2
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

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