A traffic light of mass m hangs from two lightweight cables one on each side of the light Each cable hangs at a 45 degree angle from the horizontal What is the tension in each cable?
The tension in each cable will be equal to half of the weight of the traffic light, divided by the cosine of the angle it makes with the vertical. So, the tension in each cable will be T = (mg) / (2 * cos(45)) = mg / (√2).
A traffic light of mass m hangs from two lightweight cables one on each side of the light Each cable hangs at a 45 angle from the horizontal What is the tension in each cable?
The tension in each cable can be found by setting up force equilibrium equations in the horizontal and vertical directions. Since the traffic light is at rest, the sum of the vertical forces must equal zero. The tension in each cable will be mg/√2, where m is the mass of the traffic light and g is the acceleration due to gravity.
What is force is exerted on the support ropes of a hammock when you lie in it?
When you lie in a hammock, the force exerted on the support ropes is the combination of your weight and the tension in the ropes holding you up. This force is distributed between the ropes, with each rope supporting a portion of your weight. The total force is equal to your weight divided by the number of support ropes.
There are two 5.0 g spheres each suspended from 1.0 m long threads The spheres repel each other after being charged to 91nC What is the angle theta?
The electrostatic force between the spheres causes them to repel each other. This force creates a tension in the threads, which can be broken down into vertical and horizontal components. By setting the vertical component equal to the gravitational force, you can solve for the angle theta.
How much tension if the bag is supported by 7 vertical strands That is how much tension is exerted in each strand Answer in units of N?
Assuming that all strands are vertical/ parallel to gravity and equally spaced (on a radius) around the centre of gravity then tension on each strand will be equivalent to weight x 9.81 divided by 7 equals tension in Newtons. If the strands are not normal and/or at varying distances from centre of gravity then it becomes a little more complicated. Summ of tension on strands must equal weight of bag. Tension on each strand is a ratio of it's distance from the COG of the furthest most strand. Don't forget the further from perpendicular a strand is the more tension on the strand.

Why does rope unwind For example if there are two ropes that are twisted together WHY do they unwind again?
Basic answer is that when twisting two ropes together you are causing tension in the fibers of the ropes as they bend around each other. If you don't secure both ends of the two ropes the tension will pull the ropes back to their relaxed state. Think of stretching out and wrapping a rubber band around your finger.
When a 10-N object is suspended at rest by two vertical strands of rope the tension in each rope is?
If the ropes are perfectly vertical AND both of them are indeed sharing the load, then the tension in each rope is 5N. But it would be practically impossible to have them exactly share the load, and one would wind up supporting most or all of it. The best way to make them share is to use elastic ropes, like bungees. They still would never share equally, but at least they would share. In any case, the tensions in both support strands would always add up to 10N.

What is the difference between a vertical angle and an opposite angle?
Opposite angles are the angles opposite each other on an x but vertical angles are the angles that are opposite and congruent.
Is the angle between a horizontal line and a vertical line a right angle?
Yes, the angle between a horizontal line and a vertical line is a right angle. This is because a right angle measures 90 degrees, which is the angle formed when two lines are perpendicular to each other. Since horizontal and vertical lines are defined to be perpendicular, the angle between them is indeed a right angle.

This force is distributed between the ropes, with each rope supporting a portion of your weight. The total force is equal to your weight divided by the number of support ropes.
What is the measure of each angle if both angles are vertical and supplementary?
90 degrees

What is the difference between an adjacent angle and a vertical angl?
Adjacent angles will be right by each other and equal 180 degrees. Vertical angles will be opposite and equal to each other.
Are vertical lines always equal to each other?
No. Vertical lines have the same direction but are not necessarily the same length.Therefore, two vertical lines will have the same angle but possibly not the same magnitiude.
What is the relationship between vertical angles?
Vertical angles have the same angle measure. Vertical angles are formed by two intersecting lines that look like an "x". Angles that are across from each other on this "x" are called vertical angles.
