After the NEAR spacecraft passed Mathilde, on some occasion's rocket propellant was expelled to adjust the spacecraft's momentum in order to follow a path that would approach the asteroid Eros, final destination for the mission.
A certain camera has f-numbers that range from 1.3 to 5. If the focal length of the lens is 49 mm, what is the range of aperture diameters for the camera
Cooling water from a river flows through the condenser (the low-temperature heat exchanger) at the rate of 1.2×108L/h (?30 million gallons per hour). If the river water enters the condenser at 18?C, what is its exit temperature
1. Estimate the rate of speed (length per time) at which the hair on your head grows. Use your own experience as a guide for your answer. First express your estimate in inches per second and then in meters per second. Use scientific notation.
