Answer:
Option D: 21.8 degrees
Explanation:
In a parallel RL circuit, the current in the resistor R and that in the inductor L are separated among themselves 90 degrees as illustrated in the attached image. In the image the current in the resistor is represented in orange, that of the inductor in blue, and the total current (vector addition of the previous two) is represented in red, forming a certain angle (theta) with respect to the current in the resistor. The output voltage is the same as the input voltage as measured over the resistor R.
Therefore, the phase angle that separated output voltage and total current can be obtained using the fact that tan(phase angle) = , therefore the angle is the arctangent of 4/10:
degrees.
Answer:
Explanation:
As we know that base of the slab is given as
now we know that rate of heat transfer is given as
here we know that
Also we have
Answer:
67.6 m
Explanation:
For this problem, we just need to analyze the motion of the two planes after the collision.
The two planes stick together and move with a velocity of
u = 19.3 m/s
The problem tells us that they skid until they stop: so, their final velocity is
v = 0
Since the velocity is not constant, this means that they are accelerating.
We also know that they skid for a time of
t = 7 s
Therefore, we can find their stopping distance using the following suvat equation
And substituting, we find
