Light year is the distance traveled by light in 1 year of time interval
so here we can say that the statement must have used the word light year as the distance
so we have
A) It's about 4 light-years from here to Alpha Century.
this shows the distance between two so it is correct
B) It will take me light-years to complete this homework assignment.
here it represent the light year as time so it is INCORRECT
C) A light-year is about 10 trillion kilometers.
This shows the distance so it is correct
D) It will take the Voyager spacecraft about 20,000 years to travel just 1 light-year.
It shows the distance so it is correct
E) The Milky Way Galaxy is about 100,000 light-years in diameter.
this is distance so it is also correct

The main reason for using light years, however, is because the distances we deal with in space are immense. If we stick to miles or kilometers we quickly run into unwieldy numbers just measuring the distance to the nearest star: a dim red dwarf called Proxima Centauri that sits a mere 24,000,000,000,000 miles away!

Answer:There you go
Explanation:
The rock cycle works by the rocks moving around. Weathering and erosin makes sediment or something like sand, that sand is put under a lot of pressure until it becomes a solid mass. After that heat and more pressure are added to the rock to make it metamorphic. after that it is heated again until it becomes magma. the ignious rock is made by the cooling of the lava( its lava when it gose above ground). Then the whole cycle repeats.
Answer:
The time constant is 0.26 s
Explanation:
From ohm's law,
Current (I) = potential difference ÷ resistance = 11.1 ÷ 3.19 = 3.48 A
Quantity of electricity (Q) = capacitance × potential difference = 81.9×10×^-3 × 11.1 = 0.90909 C
time constant (t) = Q/I = 0.90909/3.48 = 0.26 s
