Chapter 1: Q20DQ (page 356)

If a metal wire has its length doubled and its diameter tripled, by what factor does its Young's modulus change?

Short Answer

Expert verified

Thus, Young's Modulus of the wire remains unchanged.

Step by step solution

01

Young's Modulus

The Young's Modulus is a physical property of any material mostly elastic in nature that determines the ease of deformation of that material with respect to stress and strain applied to it.

02

Young's Modulus

Given, that a wire is transformed by doubled by its length and tripled by its diameter.

Since Young's modulus is a property independent of the dimensions of the medium or material, therefore, the change in the dimension would not affect the Young's Modulus of the wire.

Hence, this is the required answer.

Starting from the front door of a ranch house, you walk 60.0 m due east to a windmill, turn around, and then slowly walk 40.0 m west to a bench, where you sit and watch the sunrise. It takes you 28.0 s to walk from the house to the windmill and then 36.0 s to walk from the windmill to the bench. For the entire trip from the front door to the bench, what are your (a) average velocity and (b) average speed?

A plastic ball has radius 12.0 cm and floats in water with 24.0% of its volume submerged. (a) What force must you apply to the ball to hold it at rest totally below the surface of the water? (b) If you let go of the ball, what is its acceleration the instant you release it?

A lunar lander is makingits descent to Moon Base I (Fig. E2.40). The lander descendsslowly under the retro-thrust of its descent engine. The engine iscut off when the lander is 5.0 m above the surface and has a downwardspeed of 0.8m/s . With the engine off, the lander is in freefall. What is the speed of the lander just before it touches the surface?The acceleration due to gravity on the moon is 1.6m/s2.

Hot Jupiters. In 2004 astronomers reported the discovery of a large Jupiter-sized planet orbiting very close to the star HD 179949 (hence the term “hot Jupiter”). The orbit was just19 the distance of Mercury from our sun, and it takes the planet only3.09days to make one orbit (assumed to be circular). (a) What is the mass of the star? Express your answer in kilograms and as a multiple of our sun’s mass. (b) How fast (in km>s) is this planet moving?
