Answer:
Explanation:
charge, q = 2e = 2 x 1.6 x 10^-19 C = 3.2 x 10^-19 C
mass, m = 4 u = 4 x 1.661 x 10^-27 kg = 6.644 x 10^-27 kg
Radius, r = 4.5 cm = 0.045 m
Magnetic field, B = 1.20 T
(a) Let the speed is v.


v = 2.6 x 10^6 m/s
(b) Let T be the period of revolution


T = 1.09 x 10^-7 s
(c) The formula for the kinetic energy is


K = 2.25 x 10^-14 J
(d) Let the potential difference is V.
K = qV


V = 70312.5 V

Hi there!
I'm sorry your sister is struggling!
I am an edgenuity student in grade 11, I could probably help!
A trend is a line on a graph that all points seem to follow. This is best explained when thinking about line of best fit. If all your points go upward each time and are closed together, we can find the line that gets closest to each point!
Think of a trend as a pattern. The line of best fit, created by analyzing the trends, helps us guess at what the data points beyond what we have will equal
Is there any clarification she needs?
It should be noted that the student should use K = 1/2mv² with the initial speed of the block for one trial.
<h3>
Method of using the data collected.</h3>
From the complete information, the student wants to use the data collected and the known quantities from the experiment to determine the initial total mechanical energy of the block-ramp-Earth system for all trials in the experiment.
In this case, it's important to use K = 1/2mv² with the block's initial speed for one trial due to the fact that the initial speed is the same in all the trials.

Answer:
268.2 m/s (1dp)
Explanation:
600 miles = 965,606m (1mile = 1609.34m)
965606/60 = 16,0943.43 ..... (metres traveled every minute)
16,0943.43/60 = 268.2238 .....
