the answer is c) the speed and direction of travel must be constant
here's the first part but for the 2nd one all I know is that the word "compression" goes on the spirals that are closer together.
hope this helps!
Answer:10
Explanation:
You have to do speed divided by time so your answers 10
Answer:
f = 0.5 Hz
Explanation:
frequency = f
wave length = l
speed of wave = v
f = v/l → f = 3/6 = ½ = 0.5 Hz
Answer:
Explanation:
The same current flows through each part of a series circuit. The total resistance of a series circuit is equal to the sum of individual resistances. Voltage applied to a series circuit is equal to the sum of the individual voltage drops.
I = 0.33 A
= 330 mA
Capacity, P = I × t
= 2050/330
= 6.21 hours
Time, t = 6.21 hours.
