A force of 25 N is applied vertically at the end of a wrench handle that is 45 cm long to tighten a bolt in the clockwise direction. What torque is required by the bolt to keep the wrench from turning?
In order to keep the wrench from turning, the torque on the bolt must be equivalent in magnitude but opposite in direction of the torque applied by the wrench.
Fusion Reaction: In nuclear fusion light nuclei are brought together to form a relation heavier nucleus. They energy free in nuclear fusion is larger than that free in fission.
Q Define: Drift velocity. Drift velocity is described as the velocity with which free electrons get drifted towards the positive terminal, when an electric field is applied.
