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
Answer:
Total time spend = 48.18 hours (Approx)
Explanation:
Given:
Total distance = 5,300 km
Average speed = 110 km / h
Find:
Total time spend
Computation:
Time = Distance / speed
Total time spend = Total distance / Average speed
Total time spend = 5,300 / 110
Total time spend = 48.18 hours (Approx)
The current I is defined as the amount of charge Q flowing through a certain point in a time t:
which can be rewritten as
so, by using this formula we can calculate the maximum amount of charge that can flow in the circuit. In fact, the maximum current is I=15 A, while the time is
so the maximum amount of charge is
False. you have to find out how many seconds are in the 25 min. 60 x 25 is 1500sec. Then multiply 1500 by .75 to get 1,125m. There are 0.001 kilometers in a meter. Move the decimal point three spaces to convert m to km. 1,125m becomes 1.125km
