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.

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.

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 truck starts from rest and accelerates for 25 seconds to reach a velocity of 60m/s . calculate the rate of acceleration for the truck
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

An 8 kilogram cannonball is loaded into a 1000 kilogram stationary cannon. When fired horizontally the velocity of the cannonball is 300 meters per second east. Determine the cannon's recoil velocity.
Answer:
The recoil velocity of the cannon is 2.38 m/s.
Explanation:
Given;
mass of cannonball, m₁ = 8 kg
mass of stationary cannon, m₂ = 1000 kg
initial velocity of the cannonball, u₁ = 300 m/s
initial velocity of the cannon, u₂ = 0
Let the recoil velocity of the cannon, = v
Apply the principle of conservation of linear momentum;
m₁u₁ + m₂u₂ = v(m₁ + m₂)
8(300) + 1000(0) = v(8 + 1000)
2400 = v(1008)
v = 2400/1008
v = 2.38 m/s
Therefore, the recoil velocity of the cannon is 2.38 m/s.

Explanation:
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.

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!

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

Natural Resources Question 5
Which statement describes an advantage of using renewable
resources?
Select one
-They make energy more affordable
-They will increase the demand for electricity
-They will be available for many years.
-They make electricity less dangerous.
Answer:
-They will be available for many years.
Explanation:
The advantage of using renewable resources is that they will be available for many years.
Renewable resources have very fast turn over time for replenishing, therefore, they are available over an extended period time.
They are not used by consumption and so they will continually be available. This is different from the non-renewable resources which are depleted as they are being used up.
Examples of renewable resources are wind, water and air
49. A vertically hung 0.50-meter- long spring is stretched from its equilibrium position to a length of 1.00 meter by a weight attached to the spring. If 15 joules of elastic potential energy are stored in the spring , what is the value of the spring constant?
