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.
It holds more weight in the regular water.
Answer:
It remains constant
Explanation:
As we know that buoyant force on an object given as
Fb = ρ Vd g
ρ= Density of fluid
Vd=Volume displace by body
g=10 m/s²
Fb =buoyant force
So from above we can say that buoyant force does not depends on the depth. It only depends on the fluid density and volume displace by body.
So when rock gets deeper and deeper the buoyant force will remain constant.
It remains constant
Weathering the process that breaks down exposed stone and rock causing it to split apart or wear away. Different forces can cause rocks to become weathered physical weathering is caused by purely mechanical changes to the rock while chemical weathering is caused by chemical reactions
This is known to be named supernova it a time in a stars life where it has reached it's final stage. It concludes that when stars explode supernova occurs or an tear in space is created know as a "blackhole". The star can only explode once it has survived over along period of time.
