Explanation:
It is known that it does not matter at what angle the force has been applied on an object because they all are acting perpendicular to the axis.
And, expression for torque from each force is as follows.
where, F = magnitude of force
r = distance from the center
Total torque will be calculated as follows.
Nm
= 3.9 Nm
Therefore, we can conclude that the magnitude of the net torque on the wheel about the axle through the center of the object is 3.9 Nm.
Answer:
the ground when the ball hits it
Explanation:
A ball falls freely towards the Earth. If the action force is the Earth pulling down on the ball, then identify which of the following best describe the reaction force:
Answer:
greater than 0.10
Explanation:
The null hypothesis is:
The alternate hypotesis is:
Our test statistic is:
In which X is the statistic, is the mean, is the standard deviation and n is the size of the sample.
We have that:
We are testing if X is greater than 0.45, so our pvalue is 1 subtracted by the pvalue of z = t = 0.45.
z = 0.45 has a pvalue of 0.6736
1 - 0.6735 = 0.3264
So our pvalue is 0.3264, which is greater than 0.10.
So the correct answer is:
greater than 0.10
<h3>
Answer: 104.5 cubic cm</h3>
=======================================================
Work Shown:
r = radius = 1.045 cm
h = height = 30.48 cm
pi = 3.141 approximately
V = volume of cylinder
V = pi*r^2*h
V = 3.141*(1.045)^2*30.48
V = 104.547940002
V = 104.5 cubic cm
