Answer:- The speed of the satellite is 7.6 .
Solution:- It's a unit conversion problem that could be solved using dimensional analysis which is also known as train trail method.
The given speed of the satellite is 17000 miles per hour and we are asked to convert it to kilometers per second.
given:
1 Kilometer = 0.62 mile
1 hour = 3600 second
Let's use this given info and plug in the values to make the set up as:
= 7.616
We round the answer to two significant figures, since the given number(17000) has only two significant figures.
Hence, the speed of the satellite is 7.6 .

Here you need to draw a force system.
The car is the center and you have mainly two forces: velocity and gravity.
The angle they ask you for is the same angle formed by the velocity (mass* acceleration) and the gravity (mass*gravity)
And to know the angle you need to do the tangent.
Tg∡=
Both masses canceld and
Tg∡=
∡=arcTg 0.30
∡=187.35°
Answer:
Its unreactive since its outer shell is filled up and also does not form a covalent bonding.
