(a) What current is needed to transmit 100 MW of power at a voltage of 25.0 kV? (b) Find the power loss in a 1.00 -Ω size 12{1 "." "00"- %OMEGA } {} transmission line. (c) What percent loss does this represent?

You will know that the expansion of the Universe can be described by general relativity. You will know that the expansion leads to a change in the Universe over time, including temperature and density.

You will know that the first stars contained no heavy elements, making them different from later generations of stars You will understand the physical conditions under which the first stars formed
- https://phys.libretexts.org/Courses/Chicago_State_University/PH_S_1150%3A_Basic_Astronomy/12%3A_Gravitational_Lenses/12.04%3A_Weak_LensingYou will understand the difference between strong and weak lensing. You will understand that weak lensing reveals the presence of dark matter throughout the Universe.

In the case of Earth, Mars, Jupiter, or any of the planets farther out in the Solar System, we could plug in the total mass of the Sun for M (note that this is the case even for Earth, which is orbiting just at the edge of our spread-out Sun).

You will understand that mass and energy are different aspects of the same underlying quantity, and that is the total of mass and energy that is truly conserved. You will know that a tiny amount of matter can release a great deal of energy. You will understand that it is possible to produce a pair of charged particles from an energetic photon, and that the annihilation of a particle-antiparticle pair releases energy.
