Z=1/4 that is the answer to this problem hope it helped
The net force is what remains of the pull when we subtract the friction force:
Now, use the law
and solve it for the acceleration
to get the result:
The conversion factor between radians and revolution as measures of angle is 2π rad is equal to 1 revolution. Converting the given angular velocity to rev/s,
(2.8 rad) x (1 rev / 6.28 rad) = 70/157 revolution per second
Dividing the given angle, 20 rev by the velocity,
(20 rev) / (70/157 rev/s) = 44 6/7 s
Thus, the answer is approximately 44.9 seconds.
Answer:
Step-by-step explanation:
well the mean is adding all the numbers up and divide them by how many different numbers there are for example 7 9 18 41 9, first you would add them all together 41+18=59 59+(9+9) well 9+9=18 so 59+18=77 77+7=84 we're done with the First part, now we divide it by the number of different numbers that are shown, which is 5, so it's 84 divided by 5 which gives you the answer of 16.8
