1) X-component: 568.5 N, Y-component: 511.9 N
2) The horizontal force is 86.6 N and the resulting acceleration is
Explanation:
1)
In this first part of the problem, we have to resolve the force into its two components, along the x and the y direction.
The two components are given by:
where
F = 765 N is the magnitude of the force
is the angle of the force with the horizontal
Substituting, we find:
- Horizontal component:
- Vertical component:
2)
First of all, we have to find the horizontal component of the pulling force, which is given by
where
F = 100 N is the magnitude of the pulling force
is the direction of the force with the horizontal
Substituting,
Now we can find the acceleration of the wagon by using Newton's second law:
where
is the net force in the horizontal direction
m = 100 kg is the mass of the wagon
is the acceleration in the horizontal direction
Solving for , we find

Answer: Option (a) is the correct answer.
Explanation:
Photosynthesis is defined as a chemical process in which plants tend to make their own food in the presence of sunlight, water and carbon dioxide.
During this process, product formed by the plants is glucose and oxygen.
The chemical reaction equation for photosynthesis is as follows.
Therefore, we can conclude that out of the given options the correct equation is as follows.
