The flat line running through the middle of the wave - Rest Position
Distance from rest position to the crest or trough - Amplitude
Highest point of a wave - Crest
Distance from two consecutive crests or troughs - Wavelength
Lowest point of a wave - Trough
Answer:
Option (B)
Explanation:
L = 0.5 H, I = 2 A, R = 10 Ohm
V = I R
In case of dc the inductor cannot works.
V = 2 x 10 = 20 V
The answer for this specific question is false
B. heat is correct answer
Answer:
Explanation:
The distance of Earth from the Sun is and of Mars from the Sun is . Let assume that both planets have circular orbits. The centripetal accelaration can be found by using the following expression:
Since planet has translation at constant speed, this formula is applied to compute corresponding speeds:
Earth:
Mars:
Now, centripetal accelarations can be found:
Earth:
Mars:
The ratio of Earth's centripetal acceleration to Mars's centripetal acceleration is:
