Formula: Ca=Vt^2/r
centripetal acceleration(Ca)= ?
tangential speed(Vt)= 2.8m/s
Radius(r)=2m
Substitute: Ca=2.8^2/2
Ca=3.92m/s^2
Answer:

Explanation:
The detailed step by step and necessary mathematical application is as shown in the attachment.
Answer:
The beaker that is matt black heats more quickly because black attracts more heat.
Explanation:
(if you have Q1: Carbon is found in: living animals and plants, oceans, rocks, atmosphere, and fossil fuels)
Q2: Humans are burning carbon and putting it into the atmosphere.
Q3: True
Q4: While carbon dioxide is in the air waiting to be reabsorbed it traps the sun's heat.
(and if you have Q5: In the last 250 years, the amount of carbon in the air has increased by 40 percent.)
There are 3 types of faults, strike-slip fault, normal fault and reverse fault. So choices a and d will no longer be considered. Now the difference between a normal fault and a reverse fault is in a normal fault the hanging wall moves downwards and in a reverse fault the hanging wall moves upwards.
So considering the two faults and their characteristics, the answer would be b. reverse fault.
