Answer:
the gas does no work.
Explanation:
An isochoric process is a process in which the volume of a gas is kept constant.
The work done by a gas during a transformation is given by:
where
p is the gas pressure
is the change in volume of the gas
For an isochoric process, the volume of the gas does not change, so
and so, according to the previous equation, the work done by the gas is zero:
W = 0
Answer:
Circle Q
Explanation:
The flux of a field through a surface is given by:
where
F is the field strength
A is the area of the surface
is the angle between the direction of the field and the normal to the surface
In the figure, we see that the 4 surfaces have different orientations, so different angle . In the formula, we see that the flux is maximum when 
, which occurs when the field is perpendicular to the surface, and the flux is zero when 
, (because 
) which occurs when the field is parallel to the surface.
In the figure, we see that circle Q is parallel to the direction of the field, so in this case the field is zero, while in all the other cases is not.
So, the correct answer is
Circle Q
Answer:
mass is the amount of "matter" in an object. weight is the force exerted on an object by gravity
Explanation:
0 Newtons, since it's at a constant speed. Hope this helps, and Brainliest answer would be appreciated!
Using geometrical arguments, we can see that the angle of the inclined plane
is equal to the angle between Fg and the perpendicular force.
But the perpendicular force is the projection of Fg along the perpendicular axis, and Fg=mg, so the correct answer is
