Answer:
Power required, P = 0 watts
Explanation:
It is given that,
Weight of the object, W = 525 N
Time taken to move from point A to B is, t = 36 s
Distance between A and B is 3.5 m.
Power required to move an object is given by work done divided by time taken.
Work done, 
The weight of the object is acting in downward direction and object is moving in forward direction such that 
Since, cos(90) = 0
This gives, work done = 0
As a result, the power required to move that object is 0 watts. Hence, this is the required solution.
Venus. The atmosphere of Venus, in fact, is full of carbon dioxides, the main contributor to the dramatic greenhouse effect on the planet, which causes the surface temperature of Venus to reach 460 degrees Celsius. Without this effect, the surface temperature of Venus will be more similar to Earth's one (still a bit higher, given the smaller distance from the Sun).
Answer:
As the angle is increased, the acceleration of the object is increased. The explanation of this relates to the components that we have been drawing. As the angle increases, the component of force parallel to the incline increases and the component of force perpendicular to the incline decreases.
Answer:
smaller force is 20
Explanation:
Let, magnitude of the smaller force be F Newton.
Now, the resultant force makes an angle 90° with the smaller force. So, angle between resultant force and the larger force = (120° - 90°) = 30°.
So, tan 30° = (F * sin 120°) / (40 + F * cos 120°)
(1 / √3) = {F * (√3) / 2} / {40 + F * (- 1 / 2)}
80 - F = 3F
4F = 80
F = 20.
So, magnitude of smaller force is 20 Newtons.
