Answer:
The correct answer for this would be D.
Explanation:
<em>Are tight coils of DNA</em>
Answer:
0.054m/s²
Explanation:
Here we are given that a 31kg block is being pulled by two men who apply forces of 8.3N and 6.6N in opposite directions .
So we know that ,
where
is the angle between the forces .
- Since the forces act in opposite directions , the angle between them will be 180° .
- RHS is in form of (a-b)² = a² + b² -2ab inside the square root .
Now we know that ,
- And the box will move in the direction of application of 8.3N force .
Decrease the distance between poles
Increase the area between poles
If you use coils, increase the turns of the coils will help too.
