A nozzle with a radius of 0.250 cm is attached to a garden hose with a radius of 0.700 cm. The velocity of the water in the hose is 1.90 m/s and the velocity of the water in the nozzle is 14.9 m/s Required:
a. Calculate the maximum height to which water could be squirted if it emerges from the nozzle.
b. Calculate the maximum height to which water could be squirted if it emerges with the nozzle removed, assuming the same flow rate.

How does convection affect our atmosphere? our layers of earth? our oceans?

Truck traveling west on the highway experiences an acceleration to the east. what could be the cause of this acceleration

An athlete swings a ball, connected to the end of a chain, in a horizontal circle. the athlete is able to rotate the ball at the rate of 8.13 rev/s when the length of the chain is 0.600 m. when he increases the length to 0.900 m, he is able to rotate the ball only 6.04 rev/s. (a) which rate of rotation gives the greater speed for the ball? 6.04 rev/s 8.13 rev/s (b) what is the centripetal acceleration of the ball at 8.13 rev/s? m/s2 (c) what is the centripetal acceleration at 6.04 rev/s? m/s2
