Answer:
Explanation:
Given
diameter of spacecraft
radius
Force of gravity =mg
where m =mass of object
g=acceleration due to gravity on earth
Suppose v is the speed at which spacecraft is rotating so a net centripetal acceleration is acting on spacecraft which is given by
You have a picture of the homework?
Answer:
v = 349.23 m/s
Explanation:
It is required to find the orbital speed for a satellite from the center of mass.
Mass of Mars,
The orbital speed for a satellite is given by the formula as follows :
So, the orbital speed for a satellite is 349.23 m/s.
Answer:
Sulphur(iv) oxide gas
Explanation:
S + O2 — SO2
According to the equation, the element sulphur S reacts with oxygen gas O2 to form
Sulphur (iv) oxide .
I think it’s the last one, sorry if I’m wrong
