Yes. I think it is. If you are wasting your time staring at a wall, but you are enjoying it and still have work to do, you are wasting your time. Sometimes the point of wasting time is to, well waste time, but that doesn’t change the fact that you are wasting your time.
Answer:
D
Explanation:
power is the work done per time taken,
Work done is measured in Joules, Nm
time is measured is seconds s
(Nm)/s
Option B is the correct answer
C is your answer im pretty sure
Answer:
a) q = 6.27 10⁻¹⁹ C
, b) 4 electron
Explanation:
a) In this configuration of the Mullikan experiment, the sum of the forces is zero, let's use the equilibrium law of / newton
- W = 0
q E = mg
q = mg / E
Let's calculate
q = 1.1 10⁻¹⁴ 9.8 / 1.72 10⁵
q = 6.27 10⁻¹⁹ C
b) Millikan found that the minimum charge that can exist is
q₀ = 1.6 10⁻¹⁹ C
So all charge are an integer multiple of this minimum value.
q = n q₀
n = q / q₀
n = 6.27 10⁻¹⁹ / 1.6 10⁻¹⁹
n = 3.92 = 4
In our drop we have 4 electrons
