Refer to the figure below.
R = resistance.
Case 1:
The voltage source is V₁ and the current is 10 mA. Therefore
V₁ = (10 mA)R
Case 2:
The voltage source is V₂ and the current is 8 mA. Therefore
V₂ = (8 mA)R
Case 3:
The voltage across the resistance is V₁ - V₂. Therefore the current I is given by
V₁ - V₂ = IR
10R - 8R = (I mA)R
2 = I
The current is 2 mA.
Answer: 2 mA
Answer:Direct them straight across
Explanation:
Answer:800N
Explanation:
Force of repulsion = kq1q2/r^2
Q1= 20*10^-6
Q2=100*10^-6
R=150cm=0.15m
K= 9*10^9
F= 2*10^-5*1*10^-4*9*10^9/(0.15)^2
F= 2*1*9*10^-5-4+9/(0.15)^2
F= 18*10^0/(0.15)^2
F=18/0.0225
F=800N
Answer:d. Ground waves
Explanation:A P-wave is one of the two main types of seismic waves. P-waves travel faster than other seismic waves and hence are the first signal from an earthquake to arrive at any affected location or at a seismograph
