Can anybody help me with this?? (Picture included.)

uppose that white light strikes a flat piece of flint glass in air, coming in at an angle of 60 degrees to the surface (30 degre

Elodia [21]

Answer:

Explanation:

Snell's law for index of refraction of a medium is as follows .

sin i / sin r = μ

i is angle of incidence , r is angle of refraction and μ is refractive index.

sin r = sin i / μ .

As μ for blue light is greatest , angle of refraction for blue light will be least . Similarly , angle of refraction will be maximum for red light .

So maximum deviation in the direction of light will occur in blue light due to least angle of refraction because

deviation angle = angle of incidence - angle of refraction .

So the order of light from inward towards surface

= blue , green , red .

A volleyball player’s hand applies a 39 N force while in contact with a volleyball for 2 seconds. What is the impulse on the bal

nikklg [1K]

Given:
F = 39 N, the force applied
t = 2 s, the time interval in which the force is applied.

By definition, the impulse is
$I = \int_{0}^{2} F(t) dt = \int _{0}^{2} 39dt = 39*2=78 \, N-s$

Answer: 78 N-s

Which of the following statements is true for ideal gases, but is not always true for real gases?

xxMikexx [17]

Answer:

C. Replacing one gas by another under the same conditions, has no effect on pressure.

Explanation:

Ideal gas:

A gas is treated as an ideal gas if temperature is high and pressure is low.

Kinetic energy for ideal gas given as

$K.E.=\dfrac{3}{2}KT$

So when temperature of gas is increases then Average molecular kinetic energy will also increases.

The size of molecule is negligible as compare to the dimension of container. It mean that volume occupied by molecule is less as compare to the volume of container.

The between molecules is perfectly elastic.

Ideal gas equation

P V = m R T

So the option C is not always true.

Who was executed for believing that Earth revolves around the sun?

Tomtit [17]

According to research, none of these men were executed for believing that Earth revolves around the sun. Nicolaus Copernicus was the first to believe in the heliocentric view of the current solar system, but he was not killed for that view, but he died of natural means. Galileo Galilei was punished because of the heliocentric view but was only put under house arrest, and not killed. Giordano Bruno was indeed burned at stake, but it was not for his view on heliocentrism.
