The answer is attached below.
Let me know if you don't understand it and I'll explain even more for you ☺♥
<h3><u>Answer;</u></h3>
4 waves
<h3><u>Explanation;</u></h3>
Wavelength of one wave = 0.25 meters
Length of the rope = 1 meter
Therefore;
Number of waves = Length of the rope/wavelength of one wave
= 1/0.25
= 4 waves
The option that describes volume is B. the amount of space that matter occupies.
It refers to the area within which some body is contained, and is usually measured in cubic meters, or any variation of the meter.
Answer:
emf=-0.035V
Explanation:
this problem can be solved with the Lenz's law:

where PhiB is the magnetic flux. In this case we have

due to the magnetic field is constant. A is the area of the circular loop. Hence

Finally

HOPE THIS HELPS!!
It’s D the time period within pendulums are constant, distance is always measured with kilometers within cities and basic unit is always seconds.
