Explanation:
First, we will calculate the torque because of the rope wrapped around the drum as follows.
torque1, =
= 3.496 N m
Now, we will calculate the torque because of the rope around the core as follows.
torque2, =
= 3.046 N m
(Since, we are provided with any figure which means that the torque can act either in the same direction or in the opposite direction.)
So, if the torque is acting in the same direction then,
torque = torque1 + torque2
= (3.496 + 3.046) N m
= 6.542 Nm
And, if the torque is acting in the opposite direction then,
torque = torque1 - torque2
= (3.496 - 3.046) Nm
= 0.45 Nm
Answer:
ew... Decibels are measures of sound.
The work done on the bullet is force•distance. This is also equivalent to the energy it has leaving the muzzle (work energy theorem). This kinetic energy is (1/2)(0.006kg)(336m/s)^2=338.7J. Then 338.7J=F•0.83m
F=338.7/0.83=408N
C aluminum because it has iron.
A scientific law is the description of an observed phenomenon. It doesn't explain why the phenomenon exists or what causes it. The explanation of the phenomenon is called a scientific theory. It is misconception that theories turn into laws with enough research.
