Answer: The answer in scientific notation with the unit included is (1 × 10^-3m.)
Explanation:
In the field of physics, when working with too large or too small numbers, such can be expressed with the use of scientific notation. This helps to eliminate huge or ambiguous numbers with significant units. It is written is such a way that the first number is greater than or equal to 1 and less than 10 which is then multiplied by a factor of 10.
Units are symbols that are used to represent a measurement For example the unit of meters is (m).
Converting 1mm to m:
1000millimeters = 1meter
1 millimetre = X
Making X the subject of formula,
X = 1 ×1 /1000
X = 0.001m
Therefore expressing X in scientific notation is
1 × 10^-3meter (m)
I know that E.) Tension Force is one of them and B.) Gravity Force but I'm not sure about the others.
True, according to the Kinetic Molecular Theory.

5-a). Acceleration is a vector defined as the rate of change of velocity.
Its magnitude has units of [length/time²]. The SI unit is meter/second².
Its direction is the direction in which velocity is increasing.
5-b). The graph says that the object's speed is not changing.
When we look at any time, from zero to almost 50 minutes, the
object's speed is the same . . . 60 m/s . This will make it easy.
There are 60 seconds in a minute, so 30 minutes = 1,800 seconds.
In every one of those seconds, the object covered 60 meters.
It travelled a total of (60 m/s)·(1,800 s) = 108,000 meters (108 km) .
