<h3>One reason we should know what the directions of the forces acting on an object is so we can know if we have to add or subtract. same = add together, opposite = subtract from each other. Also if we don't pay attention to the direction the Net force will be wont be accurate. There will be factors that will upset the calculation.So we must know the direction of the two forces because we have to know if we are adding or subtracting and if the answer is accurate. </h3>

We Know, W = F * s
here, F = 25 N
s = 3 m
Substitute it into the expression,
W = 25 * 3
W = 75 Joule
So, your final answer is 75 J
Hope this helps!

Answer:
D
The diagram shows a simple electric generator. The needle that measures electric current will move back and forth between a largely positive and a large negative value.
- What is an electric generator?
- An electric generator is physically equivalent to an electric motor. but it converts mechanical energy into electrical energy.
- The electrical field generated is dependent on the inclination of the wire with respect to magnetic field lines, and this inclination changes over time,
because of that she will experience a varying electrical field, and thus a varying electric current will be zero.
The maximum positive value will occur when the wire is perpendicular to the magnetic field lines after one-fourth of rotation, and then zero.
Hence option C is correct.
