Answer:
The correct answer is B: 125 Nm
Explanation:
If an applied force causes rotation from upward to downward direction than the torque is clockwise and is called as negative clockwise torque. Minus sign represents the direction of the torque. SI unit of torque is Nm.
Given data:
Force = 25 N
r = 5.0 m
Formula:
Torque = r x F
= 5.0 m X 25 N
= 125 Nm
The clockwise torque is 125 Nm ( i.e -125 Nm. Here minus sign suggests that the torque is clockwise)
Money so i can get a nice body with the money hahah
The answer is it tends to be more negative down a group. This is because as you go down the periodic table, the elements have more electron shells in their atoms. This makes the outermost shells less attracted to the nucleus due to their greater distances from the nucleus. Therefore, these shells are less likely to attract electrons (hence lower electron affinity) and are even more likely to lose electrons from their outer electron orbits.
