Answer:
Average speed of the car is 36.36 miles per hour
Explanation:
It is given that,
Total distance traveled by the car, d = 200 miles
Total time taken, t = 5.5 hours
In this case, we have to find the average speed of the car. Average speed of the car is defined as the total distance divided by total time taken. Mathematically, it can be written as :
s = 36.36 miles per hour
Hence, the average speed of the car is 36.36 miles per hour.

it turns out that every object you drop falls from your hand to the ground
with the same acceleration, and hits the ground with the same speed,
no matter whether the object is light, heavy, or anything in between.
That particular value of acceleration is the "acceleration due to gravity".
On Earth, it's 9.81 meters per second². On the moon, it's 1.62 meters
per second². On Jupiter, it's 25.89 meters per second².
Why we don't generally notice it: The previous description is true if the
ONLY force on the object is the force of gravity. If it has to fall through
air on the way down, then the air can have a great effect on it. Many
museums have an exhibit where they drop things in a long tube with
all the air removed from it, and there you can see some pretty weird
stuff ... like a bowling ball, a rock, a sheet of paper, and a feather, all
falling together, with nothing fluttering.
Why everything falls with the same acceleration ? That's a separate question.

Answer;
-A triple beam balance
Explanation;
-Mass is the amount of matter in an object. Move to a different planet and an object's weight will change, but its mass will be the same. There are a couple of ways to measure mass. The Mass of an object doesn't change when an object's location changes. Weight, on the other hand does change with location.
-Mass is measured by using a balance comparing a known amount of matter to an unknown amount of matter. Weight is measured on a scale.
Mass is measured using scales, a triple beam balance, or a mass meter.
What are scales used for?
Scales are commonly used for everyday measurements, where an object's weight is indirectly measured by the force it exerts on a spring or load cell.
A triple beam balance is a type of mechanical balance that uses a combination of sliding weights to determine mass.
