The Correct Answer is <u>D.Infrared/</u> <em>INFARED has a lower frequency than visible light/</em>
So power is equal to work over time and work is force times distance, you do 5 times 3 and get 15 dividing by 2 gives us 7.5 W answer c
Answer:
There will be a force of gravity and a normal force coming from the track itself.
Explanation:
The statement is an opinion because it expresses a preference of an individual than an actual fact.
Answer:
340 seconds = 5.667 minutes
Explanation:
As we know, S = v t or t = S / v (S = 51 x 10^9 m and v = 3 x 10^8 ms^-1)
So, t = 51 x 10^9 / 3 x 10^8 = 17 x 10^1 = 170 s
For a RTT estimation, the time span will be doubled of one way propagation for transmission and receive delay.
The over all round trip time will be = 170 x 2 = 340 seconds = 5.667 minutes
