Answer:
A.
Explanation:
It will stay in motion unless for example, someone stops it from going.
Answer:
r2/r1 = 1.3
Explanation:
Electric field is given as:
E = kq/r²
At a distance r1,
226 = kq/(r1)² - - - - - - - - - - - - - (1)
At a distance r2,
134 = kq/(r2)² - - - - - - - - - - - - - (2)
From (1),
kq = 226 * (r1)²
From (2),
kq = 134 * (r2)²
Equating and then solving,
134 * (r2)² = 226 * (r1)²
(r2)²/(r1)² = 226/134
(r2)²/(r1)² = 1.687
=> r2/r1 = 1.3
<h3><u>Answer;</u></h3>
C. 12 units
<h3><u>Explanation;</u></h3>
- If the strength of the magnetic field at B is 3 units, the strength of the magnetic field at A is 12 units
- Magnetic field strength is one of two ways that the intensity of a magnetic field can be expressed.
- <em><u>The strength of the field is inversely proportional to the square of the distance from the source. This means that If the distance between two points in magnetic filed is doubled the magnetic force between them will fall to a quarter of the initial value. </u></em>
- <em><u>On the other hand, if the distance between two magnets is halved the magnetic force between them will increase to four times the initial value.</u></em>
Answer:
i'm not sure if you are asking as a personal question or a book question so i'm taking it personal.
Explanation:
I was doing a simple task that was handed to me to test my responsibility and I agreed (knowing i am responsible :3). my first thought was "man , this is easy!" but then i started seeing the other kids slaking off and quiting their tasks. I thought that was against the rules, but then i saw my bff doing it too and i thought "this should be ok then!" so i did the same. other kids where still doing it. the teacher came, saw the ones still working and smiled... but when the teacher looked at the ones slaking off omg... his face was like * im gonna kill yall* we took one big gulp and whined. the teacher awarded the ones who completed the task... the others , we had to do our original task but doubled... for 3 weeks!!! it was awful!!!
I WOULD NEVER DO THAT AGAIN!!!
