When two voltages are in-phase, they have the same frequency, and there is no time displacement between them. Both voltages cros s the baseline at the same time, going in the same direction.True / False.
1 answer:
Answer:
The answer is true.
Explanation:
AC voltages are shown with their magnitude, frequency and phase shift. If frequencies and phase shifts are same for two different voltages. It means that both voltages cross the baseline at the same time, going in the same direction.

Answer:
v = -0.45 m/s
Explanation:
Assuming the canoe was initially at rest with momentum L = 0
and that the dog's velocity is in the positive direction
conservation of momentum
0 = 15(1.2) + 40v
v = -0.45 m/s
I believe the best answer is law, as scientific laws are accepted to be true under the proper conditions.
Mass of the object m = 25 kg
Coefficient of friction Uk = 0.15
Frictional force Ff = Uk x F => Ff = Uk x m x g
Ff = 0.15 x 25 x 9.8
Frictional Force Ff = 36.75 N
According to Hooke's Law formula. The force is proportional to the displacement of the spring. I believe
Answer:
Explanation:
The formula for gravitational potential energy is
Ep = m · g · h Assuming that the acceleration is g = 10m/s²
Ep = 45.4 · 10 · 21.9 = 9,942.6 J
