Answer:
Having the inside dimensions (ID) and the outside dimensions (OD) will allow you to figure out the wall thickness on tubing. You would need to subtract the ID from the OD and then divide by two. This number is the wall thickness.
Explanation:
The correct answer is C. Mercury and Mars have the same gravitational force
Explanation:
This chart compares the different features of two planets in our solar system (Mercury and Mars). In this chart, the only numerical value or feature that is the same for both planets is gravity because for both planets gravity is 1.7 m/s2. This implies the gravitational force or the force that attracts objects towards the center of the planet is the same or that objects are pulled with the same force in both planets. Moreover, this factor depends on others such as mass, density, among others.
Based on the length of the Ethernet cable and the mass, the tension in the cable can be found to be 80 N.
<h3>How much tension is in the cable?</h3>
The tension in the cable can be found as:
= 4 x mass x length x frequency
Solving for the frequency is:
= 1 / (0.800 / 4)
= 1 / 0.20
= 5.0 Hz
The tension is therefore:
= 4 x 0.20 x 4.00 x 5
= 80N

Answer:
412.1 N
Explanation:
First of all let's calculate the total speed of the ball as it is released, which is equal to the speed of the ball + the speed of the bowler:
Now let's convert it into m/s. We know that
So
And now we can calculate the centripetal force, which is given by:
where
m = 0.16 kg is the mass of the ball
v = 40.6 m/s is the speed of the ball
r = 0.64 m is the radius of the circular path (equal to the length of the bowler's arm)
Substituting:
The velocity of a mass oscillating on a spring will show that the velocity is constant throughout the motion.
