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:
B. 22,22,23,23,22,22,23
Explanation:
The standard deviation is a measure of dispersion or variability of a data set. In order to determine the data set that has the smallest standard deviation, we shall investigate on the ranges of the data sets given. The range of a data set is simply the difference between the maximum and minimum values in a data set. A data set that has a smaller range also has a smaller standard deviation.
From the alternatives given, the data set given by alternative B has the smallest range and consequently the smallest standard deviation.
The maximum value is 23 while the minimum is 22. The range is 1.
Answer:
The tendeny of a body to continue its state either motion or rest is called inertia . First law of newton also called law of inertia .
There are three types of inertia
1. Motion inertia
2. Rest inertia
3. Directional inertia
