In order to rotate the polarization axis of a beam of linearly polarized light by 90.0° , a student places sheets p1 and p2 with their transmission axes at 45.0° and 90.0° , respectively, to the beam’s axis of polarization.
(a) what fraction of the incident light passes through p1
(b) through the combination?
(c) repeat your calculations for part (b) for transmission-axis angles of 30.0° and 90.0°, respectively.

Which is not a characteristic of a heat pump? a. it is used in air conditioners. b. it uses a refrigerant. c. it requires no work. d. it reverses the normal flow of thermal energy.

Often called simply "velocity," this is the velocity of an object at a particular moment in time.

Ineed this now one scientist feels that the changes in global climatic patterns may be good for the health of the biosphere. another scientist feels that sharp changes in climatic patterns could result in the extinction of the biosphere. which of these is the most likely reason the two scientists gave conflicting opinions on the impact of changes in the global climatic pattern? they do not have enough knowledge on the topic. they did not discuss the issue among themselves. they believe conflicting opinion strengthens science. they study different areas of science and have different scientific focuses.
