Explanation:
The area between the speed-time graph f a body and time axis measures the distance travelled by the body
Answer:
mass-to-light ratio is the ratio of the mass of a body and the light output it has. it is represented by in terms of a single number and and tells us about the kind of stars making up the most luminous population in a galaxy. the mass-to-ratio of stars is greater than 1, for dark matter is 100 times high and very low for dust. higher mass-to-ratio mean that in a galaxy on average every solar mass emits a light less than the sun of the earth solar system does.
the large mass-to-light ratio shows that gas and dust is being analyzed.
Explanation:
Velocity : Velocity is quickness of motion or action. A synonym is celerity; a simpler word is speed. In physics, velocity specifically refers to the measurement of the rate and direction of change in position of an object. It is a vector quantity that specifies both the speed of a body and its direction of motion.
Power : In physics, power is the amount of energy transferred or converted per unit time. In the International System of Units, the unit of power is the watt, equal to one joule per second. In older works, power is sometimes called activity. Power is a scalar quantity.

Average speed = (distance covered) / (time to cover the distance)
= (20 miles) / (45 minutes)
Multiply that fraction by (60 minutes / 1 hour) .
This is equal to ' 1 ', so you won't change anything except the units.
= (20 miles / 45 minutes) times (60 minutes / 1 hour)
Multiply the fractions, then cancel 'minutes' out of
the numerator and denominator.
= (20 miles x 60) / (45 x 1 hour)
= (20 x 60 / 45) miles/hour
= 26-2/3 miles/hour .
