Figure 8.9 shows the strain-stress curve for a given material. What are (a) Young’s modulus and (b) approximate yield strength for this material?

Two identical ball bearings in contact with each other and resting on a frictionless table are hit head-on by another ball bearing of the same mass moving initially with a speed V. If the collision is elastic, which of the following (Fig. 5.14) is a possible result after collision ?

It is the process in which glucose is broken down to produce energy. It produces two molecules of pyruvate, ATP, NADH and water. If the process takes place in cytoplasm of a cell and it does not require oxygen. It occurs in both aerobic and anaerobic organisms.
