Physics: Principles with Applications 7
A pendulum consists of a mass M hanging at the bottom end of a massless rod of length which has a frictionless pivot at its top end. A mass m, moving as shown in Fig. 735 with velocity v, impacts M and becomes embedded. What is the smallest value of v sufficient to cause the pendulum (with embedded m

A certain microwave oven delivers 750. watts (J/s) of power to a coffee cup containing 50.0 g water at 25.08C. If the wavelength of microwaves in the oven is 9.75 cm, how long does it take, how many photons must be absorbed, to make the water boil? The specific heat capacity of water is 4.18 J/8C ? g

Thump-Thump Data Cities lay cables (plastic-coated sensors) in roadways to gather data on traffi c volume and speeds, causing a thump-thump sound. Based on thump-thump data, you have concluded that at a volume ( V ) of 1,500 vehicles, the time required for a 10-mile trip is 24 minutes, compared to 23

Heli-Segways for Workers Consider a region with 6 million workers and two cities (A and B), each with an initial workforce of 3 million (the utility-maximizing workforce). Suppose the heli-segway (a fl ying personal transporter) replaces the automobile, cutting commuting cost and increasing the utili

Differential Equations with Boundary-Value Problems 9
The population of a community is known to increase at a rate proportional to the number of people present at time t. If an initial population \(P_0\) has doubled in 5 years, how long will it take to triple? To quadruple?
