Which of the following statements concerning nuclear scientists is most directly suggested in the passage? a) Nuclear scientists are not themselves aware of all of the facts surrounding the deuterium-tritium fusion reaction.
b) Nuclear scientists exploring the decuterium-tritium reaction have overlooked key facts in their eagerness to prove nuclear fusion practical.
c) Nuclear scientists may have overestimated the amount of lithium actually available in the Earth's crust.
d) Nuclear scientists have not been entirely dispassionate in their investigation of the deuterium-tritium reaction.
e) Nuclear scientists have insufficiently investigated the lithium-to-tritium reaction in nuclear fusion.

Athin plate moves between two parallel, horizontal, stationary flat surfaces at a constant velocity of v = 7.5 m/s. the two stationary surfaces are spaced 4 cm apart, and the medium between them is filled with oil whose viscosity is 0.9 n·s/m2. the part of the plate immersed in oil at any given time is 2 m long and 0.5 m wide. if the plate moves through the mid-plane between the surfaces, determine the force required to maintain this motion. what would your response be if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top surface (h1)? if the plate moves through the mid-plane between the surfaces, the force required to maintain the motion will be n. if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top (h1) surface, the force required to maintain the motion would be n.

At very high pressures, gases become and will eventually a) more dense; become hotter b) more dense; change to a liquid or solid c) less dense; combust d) less dense; turn into a liquid
