Answer:
60 ohms
Explanation:
![v = ir \\ 120 = 2i \\ i = 120 \div 2 \\ i = 60ohms](https://tex.z-dn.net/?f=v%20%3D%20ir%20%5C%5C%20120%20%3D%202i%20%5C%5C%20i%20%3D%20120%20%5Cdiv%202%20%5C%5C%20i%20%3D%2060ohms)

Answer:
Energy
Explanation:
Waves can transfer energy over distance without moving matter the entire distance. For example, an ocean wave can travel many kilometers without the water itself moving many kilometers. The water moves up and down—a motion known as a disturbance. It is the disturbance that travels in a wave, transferring energy.
The frequency cannot change, as it depends on the source. now, imagine light as a particle, when it's going through glass, which is a denser medium than air, is more tightly packed with particles than air is. think of it this way, will you walk faster in a crowd or on an empty street? going through the empty street (air) there are lesser objects to bump into so what do you think will happen to the speed now?
