<span>harnessing the sun's energy to produce heat or electricity is : Non-polluting
Unlike oil or gas based energy, solar energy create no dangerous emission that is dangerous for our environment.
Many scientist believed that solar energy is the answer to the environmental crisis that we currently faced.</span>
Distorted maps attempt a compromise, cutting the terrestrial surface along some arbitrarily chosen lines, then projecting each lobe (or gore, in case of interruptions, repeat periodically along related lines like meridians), separately with lower overall deformation. Gore boundaries are often designed to fall on less important areas, like oceans.
Answer:
<em>The force exerted by each string is 25 N</em>
Explanation:
<u>Net Force</u>
The net force is the vector sum of forces acting on a body. The net force is a single force that represents the effect of the original forces on the body's motion. It gives the particle the same acceleration as all those actual forces together as described by Newton's second law of motion.
The picture described in the problem is hanging at rest supported by two vertical strings. This means that the net force acting on it is zero.
Assume the magnitude of each of these equal forces is F, and the picture has a weight of W=50 N, thus the net force is:
F + F - W
The positive signs indicate an upwards direction and the negative sign means a downwards direction. Since the net force is zero:
F + F - W = 0
2F = W
F = W/2 = 50 N/2
F = 25 N
The force exerted by each string is 25 N
Two forces 3N and 4N act on a body in a direction due north From East, the equilibrant's angle is given by 
.
<h3>What are equilibrium and resultant force?</h3>
The equilibrium force is the balanced force when the net force acting is zero and is the exact opposite of the consequent force. The resultant force is one single force replaced by numerous forces.
<h3>Briefing:</h3>
3N and 4N are the two forces pulling on a body.
The forces work along the North and the East, which are perpendicular to one another.
The resultant of the forces, which is provided by the equilibrant force,
R = √(3)²+(4)²
R = 5N
From East, the equilibrant's angle is given by
