Assume that it takes 7.00 minutes to fill a 30.0-gal gasoline tank.

a) calculate the rate at which the tank is filled in gallons per second.

b) calculate the rate at which the tank is filled in cubic meters per second.

c) determine the time interval, in hours, required to fill a 1 m³ volume at the same rate.

(1 us gal = 231 in³)

An electron moves with a constant horizontal velocity of 3.0 × 106 m/s and no initial vertical velocity as it enters a deflector inside a tv tube. the electron strikes the screen after traveling 26 cm horizontally and 19 cm vertically upward with no horizontal acceleration. what is the constant vertical acceleration provided by the deflector? (the effects of gravity can be ignored.)

You have two photos of a person walking. one shows the person at the corner of third and main streets, the other shows the person at the corner of tenth and main streets. there are lampposts at every corner in this town, and the first picture shows it to be 10: 32: 00 exactly. the second picture shows it to be 10: 49: 30. you know three facts: (1) all of the clocks are synchronized; (2) there are exactly 12 equal-sized blocks per kilometer in this town; and (3) the streets that cross main in this area are numbered consecutively, with no interruptions. what is the person’s average speed in kilometers per hour?

In general what determines whether atoms will form chemical bonds?
