Answer:
First, the meters is the unit used in almost all the world today.
Then using meters as your unit will be easier to read and interpret for a larger number of people than if you use an older system, like hands or steps.
And because of the fact that almost all the world uses the meter as the unit for length, almost all the equations and formulas are written in meters.
Precision: The meter is exactly defined as:
"The length of the path traveled by light in a vacuum in 1/299,792,458 of a second"
So the meter is an exact (and accepted) unit.
Then using this unit for measures of length also provides some "
legitimacy" for you measure.
Answer:
The new kinetic energy is 9 times of the initial kinetic energy.
Explanation:
The kinetic energy of an object is given by the formula as follows :
Where
m is mass and v is speed of the body
If the speed of the body is tripled. Let v' is the new speed, v' = 3v. The new kinetic energy is E' and it is given by :
Hence, the new kinetic energy is 9 times of the initial kinetic energy.

Answer:
Most commercial aircraft typically fly at around 460-575 mph, or 740-930 km/h, according to Flight Deck Friend. But private jet speed can vary depending on a variety of factors, such as the weight onboard and the weather conditions.
She puts each block of ice in the same 3000 mL beaker, each with 2000 mL of water at room temperature, and measures the temperature before and after adding ice. Therefore, small blocks of ice will have the same temperature.
Joanna puts two blocks of ice (one larger than the other) into separate cups and fills each with water. She compares the final water temperature of the two cups after each block of ice melts.
Put each block of ice in the same 3000 mL beaker, each at room temperature, put 2000 mL of water in it, and measure the temperature before and after adding ice. This way you keep the water at the same temperature in the beginning, then the temperature changes after you add the ice, giving you a better idea of the final temperature reading.
