The angular velocity of a flywheel obeys the equation ωz(t)=A+Bt2, where t is in seconds and A and B are constants having numer
ical values 2.65 (for A) and 1.60 (for B). Required:
a. What are the units of A and B if ωz is in rad/s?
b. What is the angular acceleration of the wheel at (i) t = 0 and (ii) t = 5.00 s?
c. Through what angle does the flywheel turn during the first 2.00 s?
In a series circuit, each circuit element has the same current. The answer
is letter A. This is because the electrons flowing in a current has only a
single path to follow. There are no other path that the current moves along.
Shock waves can be observed in outer space between planets where there is very little matter. Although little, plasma does exist in outer space which allows the waves to travel.
