If the torque required to loosen a nut on the wheel of a car has a magnitude of 40.0Nm, what minimum force must be exerted by a mechanic at the end of a 30.0cm wrench to loosen the nut

Explanation:

Minimum force means that the force should be applied at a 90° angle from the wrench.

40.0Nm / (0.30m) = 133.33N.

The mimumum force is 133.33N.

double the distance = divide strength by 4

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
