Suppose a single photon strikes an electron in some material, knocking it out of its atom. Which of the following statements are true concerning the scattered photon? a. The scattered photon has greater energy than the incident photon.
b. The scattered photon has a shorter wavelength than the incident photon.
c. The scattered photon has a longer wavelength than the incident photon.
d. The scattered photon has less energy than the incident photon.

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards

there are no contact forces mentioned on the list of choices that you've provided.

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation
