Answer:
Image result for You are traveling at 16m/s for 18 seconds. What is your displacement?
The average velocity of the object is multiplied by the time traveled to find the displacement. The equation x = ½( v + u)t can be manipulated, as shown below, to find any one of the four values if the other three are known.
Explanation:
Answer:
The diode equation gives an expression for the current through a diode as a function of voltage.

Answer:
Explanation:
Q1 = 35 nC = 35 x 10^-9 C
m = 3.5 micro gram = 3.5 x 10^-9 Kg
d = 35 cm = 0.35 m
(a) The electrostatic force between the two charges is balanced by the weight of another charge.
F = m g


(b) By substituting the values

Q2 = 13.34 x 10^-12 C
Q2 = 0.0134 nC
