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 is option C. nitrogen as:-
OXYGEN- 21%
NITROGEN- 78%
CARBON DIOXIDE, ARGON, NEON and SEVERAL OTHER GASES- 1%
Iron & Nickel. There are also small doses of other unimportant garbage.
C is your answer. (Iron & Nickel)
Answer:
describe three different ways to change your velocity when youre riding a bike?
157.5J
KE=1/2 mv^2
KE= 1/2(35kg)(3m/s)^2
KE=(17.5kg)(9m^2/s^2)
KE= 157.5J
