Answer:
Nothing
Explanation:
The radius of the orbit of the Earth does not depend on the radius of the sun.
In fact, the gravitational attraction between the Earth and the Sun provides the centripetal force that keeps the Earth in orbit:

where
G is the gravitational constant
M is the mass of the sun
m is the mass of the Earth
r is the radius of the orbit of the Earth
v is the orbital speed of the earth
Re-arranging the equation for r:

Also,

where
is the angular velocity of the Earth's orbit. So we can rewrite the equation as

As we see, the radius of the orbit of the Earth, r, does not depend on the mass of the Sun, so if the sun shrank in size, the orbit remains the same.
Answer:
purchasing bonds in order to increase the money supply.
Explanation:
The Federal Reserve raises or lowers interest rates through its regularly scheduled Federal Open Market Committee. That's the monetary policy arm of the Federal Reserve Banking System.
The Fed can attempt to increase the federal funds rate by selling Treasury bills, which decreases bank reserves.
Answer:
The average speed of the Earth in its orbit is 4.74 km/s.
Explanation:
Distance between the Earth and the Sun ,r= 149.60 million km = 
Considering the movement of Earth around the Sun follows circular path.
The circumference of circular path will be give by :

Time taken by Earth to complete revolution around earth ,T= 1 year
1 year = 365 days
1 year = 31,536,000 seconds
T = 31,536,000 seconds
Speed of the Earth around the Sun :S


The average speed of the Earth in its orbit is 4.74 km/s.
Answer:
Linear velocity of a rider in a capsule that is located at the perimeter of the wheel = 0.2355 m/s
Explanation:
Diameter = 135 m
Radius, r = 0.5 x 135 = 67.5 m
It revolves at a constant rate and takes 30 minutes
Period, T = 30 minutes= 1800 s

Linear velocity, v = radius x angular velocity
v = 67.5 x 3.98 x 10⁻³ = 0.2355 m/s
Linear velocity of a rider in a capsule that is located at the perimeter of the wheel = 0.2355 m/s
When developing a question for a scientific inquiry, the question will ideally D. all of these.
When it comes to a scientific inquiry, it is important that the question identify variables, be measurable, and not just simply ask why. There have to be a couple of variables, you have to be able to measure the results, and to prove them, supported by evidence.
