The movement of the planets and other celestial bodies in the solar system is actually caused by the sun's gravitational pull or force.
Just like the moon orbits the earth because of the gravitational pull by the earth so does gravitational pull by the sun causes planets' and other celestial bodies' orbit.

<u><em>Answer:</em></u>D. Ask her instructor questions about it the next day
<u><em>Explanation:</em></u>We are given that Lana doesn't understand everything she's supposed to learn from the homework.
<u>Let's check the options:</u><u>1- start working on it eve earlier</u>
We know that she works on the homework as soon as she can. Working on it even earlier will not help her understand the difficult parts
<u>2- put it off until she's ready to work on it</u>
This is not the best option as it wont help her understand difficult parts. On the contrary, she might lose the time she has to practice the parts she understands and gain as much knowledge as possible
<u>3- Only work on it directly before going to class.</u>
this is the same as option 2. She might not even be able to finish it before the class
<u>4- Ask her instructor questions about it the next day</u>
This is the best solution as it will help her recap what she needs to learn and understand any difficult concepts as soon as possible which will help optimize her benefits

Answer:
and 
Explanation:
a) We need first to identify the Period from the one-quarte 'time' given. That is

Then the period is,

From this Period we can calculate the radio,

Rearrange for r,

We know can calculate the Magnetic force,

b) To find the charge we only use the Force in terms of the electric field, that is

Rearrange to q,
