Answer:
Wind speed
Another very old approach to measure wind speed is through the use of a pressure tube
Microbars per second
Earthquake intensity
The currently accepted method is the moment magnitude scale, which measures the total amount of energy released by the earthquake.
The Richter scale is used to determine the intensity of earthquakes
Step-by-step explanation:
Answer:
b. m = 2, b = 4
Step-by-step explanation:
y = mx + b
m = slope and b = y-intercept
The slope is 2 cause it's going up 2 squares while only going to the right one square each time, so u could right 2/1 but it's not necessary so just 2. And the intercept is 4 because that's where the line intercepts the y-axis.
We are given the first term and the common ratio, this means they belong to a geometric series.
For the given series:

Each term of the geometric series is obtained by multiplying the previous term by common ratio.
So the next terms will be:
-4.5, -6.75, -10.125, -15.1875, -22.78125
The general formula for the G.P would be:

On plotting the series, the result will be like this:
This shape is trapezoid
top of the trapezoid is 10 (12-2)
and the bottom is 4 (6-2)
the height in 3 (3-0)
so the area will be

the area is 21
Answer: other than 7
Step-by-step explanation:
Given
Equation is 
For an equation to have no solution, the missing number can be any number other than 7
because if we put 7 then it justifies the equation i.e.
while on the other hand for a number other than 7, it does not justify the equation.
