True , because gravity is a force of nature. Matter (energy) does attract other matter
True because cooler particles have less kinetic energy in them
Directly outside of the nucleus you have a membrane
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
Therefore
the tension in rope 2 is

Answer:
1) No, the car does not travel at constant speed.
2) V = 9 ft/s
3) No, the car does not travel at constant speed.
4) V = 5.9 ft/s
Explanation:
In order to know if the car is traveling at constant speed we need to derive the given formula. That way we get speed as a function of time:
V(t) = 2*t + 2 Since the speed depends on time, the speed is not constant at any time.
For the average speed we evaluate the formula for t=2 and t=5:
d(2) = 8 ft and d(5) = 35 ft
Again, for the average speed we evaluate the formula for t=1.8 and t=2.1:
d(1.8) = 6.84 ft and d(2.1) = 8.61 ft
