That's false. Think about a stone or a baseball, during the first
several seconds after you tossed it straight up, before it reaches
its maximum height and starts to come down again.
There's no upward force on it during that time.
Also, after a roller coaster reaches the top of the FIRST hill, there's
no upward force on it for the whole rest of the ride, even though it
coasts up many more hills.
The wavelength of light (ʎ) and the frequency (f) has the
following relationship:
ʎ = c / f
where c is the speed of light, therefore:
ʎ = (3 x 10^8 m/s ) / 6.44 × 10^13 s-1
<span>ʎ = 4.66 x 10^-6 m = 4.66 x 10^3 nm</span>
The complete question is this: This figure (Figure 1) shows a container that is sealed at the top by a movable piston. Inside the container is an ideal gas at 1.00 atm, 20.0 ∘C, and 1.00 L. This information will apply to the first three parts of this problem.
A) What will the pressure inside the container become if the piston is moved to the 1.20 L mark while the temperature of the gas is kept constant?
Explanation:
It is given that,
= 1 atm, = 1 L
= ? , = 1.20 L
As the temperature is constant. Hence, find the value of as follows.
=
=
= 0.833 atm
Thus, we can conclude that the pressure inside the container is 0.833 atm.
Explanation:
C.
Object A will require more force to be set in motion but will travel faster than object B.
