A ball is thrown straight up. For which situation are both the instantaneous velocity and the acceleration zero?

leva [86]

The correct option is b i.e none is correct.

The instantaneous velocity would be zero at the top but the acceleration would not be zero at that point. This is because the acceleration is the rate of change of velocity. since, the velocity is not constant, hence the acceleration would not be zero. The correct answer would be option b: None is correct.

What is the equivalent resistance?

mote1985 [20]

Answer:

C 3.33 Ω

Explanation:

From the equation given 1 / Rtot = 1/10 + 1/5 = 3/10

then Rtot = 10/3 = 3.33 Ω

As an aside:

When there are only two resistors in parallel, the equivalent R is

= R1*R2 / (R1 + R2) = 10*5 / (10+5) = 50 / 15 = 3.33 Ω
