A) 330 N
Explanation: Her weight must be evenly distributed between the chains (assuming they are at an even level), so you divide 660 by 2 and get 330
Answer:
t = 20s
Explanation:
In order for the police car to capture the other car, both cars must travel the same length.
The distance traveled by the first vehicle is:
S = ^ Vt = 40t, where t represents the elapsed time and V the vehicle speed.
The distance traveled by the police car is:
S = at ^ 2/2 = 2t ^ 2, where t represents the elapsed time, a is the acceleration of the car.
As the distances traveled are equal:
40t = 2t ^ 2 in this way t = 20s
The SI unit for molar mass is grams/mole.
