The speed of the car is 60 m/s
Explanation:
The speed of an object is a scalar quantity telling "how fast" the object is moving, regardless of its direction. It can be calculated as follows:
where
d is the distance covered
t is the time taken
For the car in this problem, we have
is the distance covered
is the time taken
Subsituting into the equation, we find the speed:

Answer:
False
Explanation:
No. The buoyant force on an object is the portion of its weight that appears to vanish
when the object is in any fluid (could be either a liquid or a gas).
If the object happens to float in a particular fluid, then the buoyant force at that moment
is equal to the object's weight.
Notice that the buoyant force on an object will be different in different fluids.

I don't understand what you are looking for. I can tell you that the speed of molecules does change during state changing.
