2. Find the acceleration of an object that takes 4 s to go from 10 m/s to 14 m/s. * O a. 28 m/s2
O b. 14 m/s2
O c. 1 m/s2
O d. 4 m/s2

What is the magnitude of the resultant vector round your answer to the nearest tenth

Amichelson interferometer operating at a 600 nm wavelength has a 3.02-cm-long glass cell in one arm. to begin, the air is pumped out of the cell and mirror m2 is adjusted to produce a bright spot at the center of the interference pattern. then a valve is opened and air is slowly admitted into the cell. the index of refraction of air at 1.00 atm pressure is 1.00028.how many bright-dark-bright fringe shifts are observed as the cell fills with air?

Juliette sets the initial velocity to +10 m/s, the acceleration to zero, and clicks “start.” how can shakina describe the subsequent motion of the car juliette controls?
