Explanation:
The average speed is the displacement of a particle divided into a time in which the displacement occurs. Instead, instantaneous speed is the limit of the average speed as the time interval approaches zero.
<u><em>In physics expressions </em></u>
Instantaneous speed=
b) Speed denotes distance traveled divided by time, and instantaneous speed measures how quickly and in which direction does it move
"The number of waves per second will increase" is the statement among the choices given in the question that will be true if you increase the frequency of a periodic wave. The correct option among all the options that are given in the question is the first option or option ANSWER --> <u>A </u><-- ANSWER. This is 100% correct, I know your module is on edmentum huh, cheers!
Power = (voltage) x (current)
350 watts = (120 volts) x (current)
350 watts / 120 volts = current
current = 2.917 Amperes continuously
We can solve this using right-hand rules! :)
Going into chamber 1, the velocity points down and the centripetal force points to the right, so the magnetic field points: into the page.
For chamber 2, the velocity points to the right and force points down, so the magnetic field points: out of the page.
Going into chamber 3, velocity points down and force is to the left, so the magnetic field is: out of the page.
And for chamber 4, velocity points left and force points down so the magnetic field points: into the page!
Hope this makes sense and helps :)
