Answer:
FALSE
Explanation:
Temperature inversion usually refers to the situation where a warm air lies over a cooler air that is present from the surface of the earth up to a certain height.
Normally, the temperature increases with increasing height. But, in the case of temperature inversion, the reverse of it takes place. This layer of inversion may occur at any place within the level of the troposphere.
This temperature inversion obstructs the atmospheric flow due to which the air mass present over a particular area become stable, resulting in a number of weather patterns.
On the other hand, greenhouse gases are those gases that can hold the incoming solar energy and radiate back into the atmosphere, thereby resulting in an increase in temperature of the atmosphere. Example, CO₂, CFC, H₂O and CH₄.
Hence, the above-given statement is false.
Convection of liquid in the metal core,
Evidence from safari to explain:
heat from the Earth's interior causes currents of hot rising magma and cooler sinking magma to flow, moving the plates of the crust along with them.
The dog walked 5 meters backwards in the first 10 seconds, then 5 meters forward from 10-20 seconds. After 20 sec he was back where he started. Displacement (20sec) = zero.
Volume of the original block (V) of length (l), width (w) and height (h) is given by the following equation
hence volume of original block, V = (6)(4)(10) = 
Now say we cut this block in two equal parts, than the length of new block will be 
; where as its width and height will be same as of original block i.e. 4 cm and 10 cm respectively.
So, Volume of half-block is 
; or we can say that the volume of half-block is half that of orignal block.
Answer:
Average 
= 11.25 cm
standard deviation = 0.129 cm
Explanation:
The data provided in the question is:
x₁ = 11.4 cm
x₂ = 11.3 cm
x₃ = 11.2 cm
x₄ = 11.1 cm
total number of data points, N = 4
Now, the average is calculated as:
Average = 
substituting the values in the above formula we get,
Average = 
Average = 11.25 cm
Now the standard deviation is calculated as:
standard deviation = 
substituting the values in the above equation we get,
standard deviation = 
or
standard deviation = 0.129 cm
