Nastasia [14]

Answer: The last part of the question has some details missing which is ; (Assume that the molecule's velocity is perpendicular to the two sides that it strikes.) molecule v=482 m/s molecule momentum=2.56 x 10^(-23)

Explanation:

The momentum of the molecule is 2.56 x 10^(-23) .
Particle hits the wall and bounces.
Momentum is reversed. Change in momentum = impulse
This is Force x time.
Momentum change happens at a wall after each trip.

time required = distance /speed

= 0.17 X 2/(482 m/s)

Average force = impulse / time

= 2 x 482 x 2.56 x 10^(-23) / (0.17 x 2)

= 7.76 x 10^20N, is the average force the molecule exerts on one of the walls of the container.

Which statement best describes Cleo's mistake? Light travels through air and water in angled, scattered paths. Light does not ch

pashok25 [27]

The question (obtained from the internet);

Cleo stated that light travels through air in straight paths, and when it moves from air to water, light changes direction, speeds up, and bends towards the normal

Answer:

The statement that best describes Cleo's mistake is;

Light slows down when it moves from air into water

Explanation:

The question;

Cleo stated that light travels through air in straight paths, and when it moves from air to water, light changes direction, speeds up, and bends towards the normal

The speed of light in water = 225,000 km/s

The speed of light in air = 299,702,547 m/s

The speed of light in vacuum = 299,792,458 m/s

Therefore, light slows down when it moves from a less dense medium to a denser medium

Light moves closer (bends) towards the normal when it moves from air into water. Light therefore, changes direction, and light moves in straight path which is known as rectilinear motion

Therefore, the statement that describes Cleo's mistake is that light actually slows down when it moves from air into water.

How does atomic number relate to mass number

drek231 [11]

Mass Number. An element's mass number (A) is the sum of the number of protons and the number of neutrons. ... Protons and neutrons both weigh about one atomic mass unit or amu. Isotopes of the same element will have the same atomic number but different mass numbers.
