For physics, I would recommend to just keep doing practice problems and reviewing notes. Repetition of the same concepts will help drill it into your brain. Hope that helps!
Answer:
5069.04 seconds
Explanation:
The parameter we are looking for is called the Orbital period of the Hubble Space Telescope.
It is given as:

where r = radius of orbit of Hubble Space Telescope
G = gravitational constant = 
M = Mass of earth
We are given that:
r = radius of the earth + distance of HST from earth
r = 
M = 
Therefore, T will be:


The orbital period of the Hubble Space Telescope is 5069.04 seconds.
Most modern games have a sense of real-world physics, but not exactly perfect. In a video game, the realistic movement or action greatly depends on the precision of coding. In real life, movement isn't done or programmed by a strand of code.
Your presentation sounds interesting, being a gamer myself, I would look forward to it. But the choice lies in your hands. If you do reconsider, be sure you have a backup plan. Good luck to you.
Answer:
C. Influenced by the Sun's electromagnetic field
Explanation:
"Sunspots occur in pairs because each is one side of a loop of the Sun's magnetic field that reaches the Sun's surface. Solar prominences are the plasma loops that connect two sunspots."
