Answer:B
Explanation:The light waves are caught by the front light sensor on the TV and the remote lets off different variations of light depending what you press.
Answer:
v = 0.5 m/s.
Explanation:
Total distance, d = 20 m + 20 m = 40 m
Total time taken, t = 30 s + 50 s = 80 s
The average speed of an object is the total distance divided by time taken. So,
So, the average speed of the object is 0.5 m/s.
The rate of molecular motion will increase as the temperature rises. At the same temperature, an object with less massive molecules will have a faster molecular speed. Two objects with the same average kinetic energy will have the same temperature when kinetic temperature is applied.
it all depends on what your looking for

The Permian–Triassic extinction event, also known as the P–Tr extinction, the P–T extinction, the End-Permian Extinction and colloquially as the Great Dying, formed the boundary between the Permian and Triassic geologic periods, as well as between the Paleozoic and Mesozoic eras, approximately 252 million years ago
