1)
4)
6)
7)
those are all examples of projectiles being in motion
Answer:
False.
Explanation:
provided the distance between the forces remains the same, the force will <em>increase</em> with increased charge, whether attractive or repulsive.
We have that the tension in rope 2 is mathematically given as
the tension in rope 2 is
From the question we are told
A crate hangs from a rope that is attached to a metal ring.
The metal ring is suspended by a <em>second </em>rope that is attached <u>overhead </u>at two points, as shown.
What is the angle if the tension in rope 1 is 0.640 times the tension in rope 2?
<h3> Angle of the tension</h3>
Generally the equation for the <em>Tension</em> is mathematically given as
![Tcos\theta+0.640\theta-T_1=0\\\\Therefore\\\\ZTcos \theta-0.640T=0\\\\Cos=0.32\\\\\theta=71.3\\\\](https://tex.z-dn.net/?f=Tcos%5Ctheta%2B0.640%5Ctheta-T_1%3D0%5C%5C%5C%5CTherefore%5C%5C%5C%5CZTcos%20%5Ctheta-0.640T%3D0%5C%5C%5C%5CCos%3D0.32%5C%5C%5C%5C%5Ctheta%3D71.3%5C%5C%5C%5C)
Therefore
the tension in rope 2 is
![\theta=71.3](https://tex.z-dn.net/?f=%5Ctheta%3D71.3)
