A spacecraft has an initial velocity component of vox=34 m /s and an acceleration component of ax=19m/s^2. In the y direction the analogous quantities are voy = 10 m/s and ay=16m/s^2 After a time of 6.3 s find a) x and vx b) y and vy c) the final velocity (magnitude and direction) of the spacecraft

What are the differences and similarities of a compression wave and a transverse wave?

Which lists the main components of darwin’s theory of evolution? a. random mutations drive evolution; the evolution of a population happens slowly; organisms have common ancestors; organisms do not change. b. natural selection drives evolution; the evolution of a population happens slowly; organisms have common ancestors; organisms change over time. c. natural selection drives evolution; the evolution of a population happens rapidly; organisms have common ancestors; organisms change over time. d. random mutations drive evolution; the evolution of a population happens rapidly; organisms have common ancestors; organisms do not change.

Arod of some material 0.20 m long elongates 0.20 mm on heating from 21 to 120°c. determine the value of the linear coefficient of thermal expansion [in (degrees c)^-1] for this material.
