If you were referring to the question :
If a 2.2 kg textbook weighs 19.6 newtons on Venus, what is the strength of gravity on that planet then read on.
Weight is the force of gravity on an object and it can be computed using the formula:
W = mg
where:
W = weight (N)
m = mass (kg)
g = acceleration due to gravity
So we know the weight and the mass of the object, all we do is plug it into our formula and solve for what we do not know.
<h2>Answer:</h2>
Variance
<h2>Step-by-step explanation:</h2>The standard deviation is related to the variance. The standard deviation measures the variation or dispersion of a set of data and is represented by the Greek letter sigma , while the variance measures how far a set of numbers are spread out from their average value. The variance is obtained by squaring the standard deviation, so the variance can be found as
Answer:

60.67 meters
Step-by-step explanation:
A worker with a speed of 3.0 m/s with respect to a car, starts to walk from one end of the car to the other in the direction of motion of the car.
As the car is 28 m long, then the worker will reach the other end of the car in seconds. (Answer)
Now, the car is moving with a speed of 6.5 m/s and in the time of 9.33 seconds, it will move by meters. (Answer)
