The gas will remain a gas and the energy will be transformed into heat raising the temperature
(Some very rare exceptions might occur)
Answer: The canyon wall is 850 m away from the person
Explanation:
Well, the speed of sound
in air at
is defined as
, this can be calculated by the following equation:
(1)
Where:
is the Heat capacity ratio for air
is the Universal Gas constant
is the temperature in Kelvin
is the air molar mass

(2)
Now that we know the speed of sound, we can use the following equation to find the distance between the person and the canyon wall:
(3)
Where:
is the distance between the person and the canyon wall
is the time it takes to the sound wave to travel from the person and then go back
Isolating
:

(5)
Finally:
Answer:
The radius r of the metal sphere.
Explanation:
From Gauss's law we know that for a spherical charge distribution with charge
, the electrical field at distance
from the center of the sphere is given by
What is important to notice here is that the radius of the sphere does not matter because any test charge sitting at distance
feels the force as if all the charge
were sitting at the center of the sphere.
This situation is analogous to the gravitational field. When calculating gravitational force due to a body like the sun or the earth, we take not of only the mass of the sun and the distance from it's center; the sun's radius does not matter because we assume all of its mass to be concentrated at the center.
Answer:
see that there is no dependence on speed, so the work remains constant
Explanation:
Work is defined by the expression
W = F. d
where the boldface indicates vectors, this equation can be written in scalar form
W = f d cos θ
where θ is the angle between force and displacement.
We see that there is no dependence on speed, so the work remains constant
The power is
P = W / t
P = f d / t
p = F v
we see that the power is the one that depends on the speed of the body
