Answer:
200 m
Explanation:
Both Jerry and Tom start at the end of the pipe where the cheese is. Jerry then runs into the pipe at 20 m/s while Tom chases him at 10 m/s. When Jerry reaches the other end of the pipe, where Tom's cousin is, he turns around. Eventually, he reaches Tom again, so he turns around again. This continues until both Tom and Jerry reach the end of the pipe where Tom's cousin is.
We need to find the distance traveled by Jerry. We already know Jerry's speed, so we just need to find the time. We can do that using Tom's speed and the length of the pipe.
x = vt
100 m = (10 m/s) t
t = 10 s
So both Tom and Jerry run for 10 seconds. Since Jerry runs at a speed of 20 m/s, the distance he travels is:
x = vt
x = (20 m/s) (10 s)
x = 200 m
Jerry runs a distance of 200 meters.

Answer:
Venus
Explanation:
Venus is the second plate in the solar system. It is a terrestrial planet and it is part of the inner rocky planets.
In Venus, it rains sulfuric acid but the rain never reaches the surface before it becomes evaporated. The acid forms from the combination of sulfur oxide and water in the atmosphere at a height of about 42km. As it condenses and falls, it becomes evaporated back at lower elevations. The surface is therefore protected from the sulfuric acid rain.
The sulfur oxide and water vapor must have been derived from volcanic activities in geologic times past.
