Answer:
The answer is the First One
Explanation:
Electromagnets can work with a magnetic source, and not just electric. sorry if my answer turns out to be wrong
Answer:
(a) T1 = 938.3lb
(b) R = 665.5lb
The detail solution to this problem can be found in the attachment below.
This problem was solved by resolving the forces along the vertical and horizontal and equating to Rx and Ry respectively. Rx = 0 because the resultant is directed along the vertical.
Explanation:
See attachment below for the full solution.
Thank you for reading.
Ok so momentum is the product of mass and velocity. Its SI unit is Kg m/s
The marble's velocity is 0.5 cm/s and it's mass is 1.5.
Multiply this -> 0.5 * 1.5 = 0.75 g cm/s
Usually everything in Physics is converted into SI units therefore the SI measurement of the marble is 0.00000075 Kg m/s
Hope this helps :).
The weight of the other object placed 1 m from the fulcrum that balances the other object is 2.5 N.
<h3>
Principle of moment</h3>
The weight of the second object is determined by applying principle of moment as shown below;
take moment about the pivot,
sum of clockwise moment = sum of anticlockwise moment
F₁r₁ = F₂r₂
5 x 0.5 = F₂ x 1
2.5 N = F₂
Thus, the weight of the other object placed 1 m from the fulcrum that balances the other object is 2.5 N.
