Answer:
<h3>The answer is option A</h3>
Explanation:
To find the mass of an object given it's acceleration and the force acting on it we use the formula
From the question
force = 500 N
acceleration = 5.0 m/s²
We have
We have the final answer as
<h3>100 kg</h3>
Hope this helps you
Answer:1.513 rps
Explanation:
Given
Diameter of cylindrical space
When the station rotates it creates centripetal acceleration which is given by
Now it must create the effect of gravity so
and
Thus
Answer:
a) To the nearest tenth the average value of the measures is 217.4cm
b) The standard deviation for the four measurements is 0.415
Explanation:
The average is the result of adding all the values and dividing by the number of measures, in this case 4 then
a) To the nearest tenth the average value of the measures is 217.4cm
The standard deviation equals to the square root of the variance, and the variance is the adition of all the square of the difference between the measure and the average for each value divided by the number of measurements
So first, we must calculate the variance:
.
.
.
.
.
This represent the difference between the average and the measurements.
Now calculate the standard deviation
Standard deviation =
Standard deviation =
Standard deviation = 0.415
b) The standard deviation for the four measurements is 0.415
This measure represent a standard way to know what is normal in this sample. so the differences between the average should be of ±0.415
