The electron won't be traveling because it is as u say "fixed in place".
I believe it’s D, all the others seem out of context.
We'll find the car's speed first, and then use that to find the velocity.
Speed = (distance covered) / (time to cover the distance)
Speed = (240 miles) / (3 hours)
Speed = (240/3) · (miles/hours)
Speed = 80 mile/hour
Now to convert the units, we'll use
-- 1 mile = 1,609 meters
-- 1 hour = 3,600 seconds
(80 miles/1 hour) · (1,609 meter/1 mile) · (1 hour/3,600 second) =
(80 · 1,609 · 1) / (1 · 1 · 3,600) (mile · meter · hour / hour · mile · second) =
35.76 meter/second
Now, to make a velocity, all we need to do is to add the direction to the speed.
So the car's <em>velocity</em> is <em>80 mi/hr south</em>, or <em>35.76 meter/sec south</em> .
The answer is
free energy.In fact, in thermodynamics, the free energy of a system is defined as the energy that can be converted to do work. Helmholtz definition of free energy, for instance, is:
where U is the internal energy, T the temperature and S is the entropy
Answer:
35.2 ps
Explanation:
Hello!
A US short ton is equal to 2 000 pounds, therefore:
2.25 tons = 4500 pounds
Now lets convert the area of each tire footprint:
1 cm = 0.393701 in
12.5 cm = 4.92126 in
16.5 cm = 6.49607 in
Therefore, the area of the footprint is: 31.9688 in^2
Then, the pressure exerted by the car is given by the weigth devided by the total area, that is 4 times the area of the footprint :
4500 /(4 * 31.9688) psi = 35.1906 psi
Rounding to the first tenth
35.2 psi
