PLEASE HELP ASAP!! An airplane increases its speed at an average rate of 15 m/s2. If the airplane accelerates from 114.5 m/s to 143.2 m/s, the time required to do so would be s. Round your answer to two significant figures.

Translation can be considered to have three phases or steps: initiation, protein synthesis, and termination. give a detailed summary of the factors and molecules involved with each step and, where appropriate, compare/contrast the differences between prokaryotic and eukaryotic translation.

Aparticle initially moving east with a speed of 20.0 m/s, experiences an acceleration of 3.95 m/s, north for a time of 8.00 s. what was the speed of the particle after this acceleration, in units of m/s? give the answer as a positive number.

How does the amount of energy required to hold each proton and neutron in the nucleus compare to the energy released when they are removed?
