Answer:
Minimum capacitance = 200 μF
Explanation:
From image B attached, we can calculate the current flowing through the capacitors.
Thus;
Since V=IR; I = V/R = 5/500 = 0.01 A
Maximum charge in voltage is from 5V to 4.9V. Thus, each capacitor will have 2.5V. Hence, change in voltage(Δv) for each capacitor will be ; Δv = 0.05 V
So minimum capacitance will be determined from;
i(t) = C(dv/dt)
So, C = i(t)(Δt/Δv) = 0.01[0.001/0.05]
C = 0.01 x 0.0002 = 200 x 10^(-6) F = 200 μF
Answer:
See below
Explanation:
Measure the distance and the amount of time to cover that distance
then speed = distance / time
It's by number of protons
Answer:
a) False.
b) True.
c) Flase.
Explanation:
a) An experiment proposes a possible explanation for a natural phenomenon.
False: An experiment doesn't propose possible explanation for a natural phenomenon. Actually, an experiment is designed to test already proposed explanations which normally are first developed in a more <em>theorical </em>context.
b) A experiment must be stated in a way that it can be tested by experiments.
True.
b) An experiment is a theory that has been validated many times by many scientists.
Flase: An experiment is no a theory, but a tool to test theories.
