Chapter 11: Q7Q (page 292)

Add \(\left( {{\bf{9}}{\bf{.2 \times 1}}{{\bf{0}}^{\bf{3}}}{\bf{ s}}} \right){\bf{ + }}\left( {{\bf{8}}{\bf{.3 \times 1}}{{\bf{0}}^{\bf{4}}}{\bf{ s}}} \right){\bf{ + }}\left( {{\bf{0}}{\bf{.008 \times 1}}{{\bf{0}}^{\bf{6}}}{\bf{ s}}} \right)\).

Short Answer

Expert verified

The correct answer of the addition is \(1.0 \times {10^5}{\rm{ s}}\).

Step by step solution

01

Writing the giving data

Addition is defined as the process in which the combined or total result of two or more values can be obtained.

The data given is

\({T_1} = 9.2 \times {10^3}{\rm{ s}}\), \({T_2} = 8.3 \times {10^4}{\rm{ s}}\), and \({T_3} = 0.008 \times {10^6}{\rm{ s}}\).

02

Solving the addition using the rules of significant figures

The value obtained from the addition of the given values is:

\(\left( {9.2 \times {{10}^3}{\rm{ s}}} \right) + \left( {8.3 \times {{10}^4}{\rm{ s}}} \right) + \left( {0.008 \times {{10}^6}{\rm{ s}}} \right) = 10.02 \times {10^4}{\rm{ s}}\)

According to the rules of significant figures in addition, the final answer is written in numbers having the least digits after the decimal.

Thus, the final answer is \(1.0 \times {10^5}{\rm{ s}}\).

Agent Arlene devised the following method of measuring the muzzle velocity of a rifle (Fig. 11–52). She fires a bullet into a 4.148-kg wooden block resting on a smooth surface, and attached to a spring of spring constant k= 162.7 N/m. The bullet, whose mass is 7.870 g, remains embedded in the wooden block. She measures the maximum distance that the block compresses the spring to be 9.460 cm. What is the speed v of the bullet?

At t = 0, an 885-g mass at rest on the end of a horizontal spring (k= 184 N/m)is struck by a hammer which gives it an initial speed of 2.26 m/s. Determine (a) the period and frequency of the motion, (b) the amplitude, (c) the maximum acceleration, (d) the total energy, and (e) the kinetic energy when x =0.40A where A is the amplitude.

A sound wave in air has a frequency of 282 Hz and travels with a speed of 343 m/s. How far apart are the wave crests (compressions)?

An earthquake-produced surface wave can be approximated by a sinusoidal transverse wave. Assuming a frequency of 0.60 Hz (typical of earthquakes, which actually include a mixture of frequencies), what amplitude is needed so that objects begin to leave contact with the ground? (Hint: Set the acceleration a > g.)

A 62 kg person jumps from a window to a fire net 20.0 m directly below, which stretches the net 1.4 m. Assume that the net behaves like a simple spring. (a) Calculate how much it would stretch if the same person were lying in it. (b) How much would it stretch if the person jumped from 38 m?
