Suppose you increase your walking speed from 6 m/s to 15 m/s in a period of 2 s. what is your acceleration?

Answer

4.5 m/s²

Explanation

Acceleration is defined as the rate of change of velocity with time.

The formula for finding acceleration is =change in velocity/change in time

change in velocity=15m/s - 6m/s=9m/s

change in time =2s-0s=2s

Acceleration is given by⇒9m/s ÷ 2s =4.5m/s²

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products
