Chapter 1: Q30DQ (page 328)

A bullet spins on its axis as it emerges from a rifle. Explain how this prevents the bullet from tumbling and keeps the streamlined end pointed forward.

Short Answer

Expert verified

The bullet spins on its axis after emerging from the rifle.

Step by step solution

01

Concept used

Conservation of angular momentum: Angular momentum of a system is conserved as long as no external torque is acting upon it.

02

Explanation

If a bullet spins while traveling through the air, because of the conservation of angular momentum, more force, as well as torque, is required to tumble the bullet. Thus, it remains streamlined and pointed forward.

Calculate the earth’s gravity force on a 75-kg astronaut who is repairing the Hubble Space Telescope 600 km above the earth’s surface, and then compare this value with his weight at the earth’s surface. In view of your result, explain why it is said that astronauts are weightless when they orbit the earth in a satellite such as a space shuttle. Is it because the gravitational pull of the earth is negligibly small?

The “direction of time” is said to proceed from past to future. Does this mean that time is a vector quantity? Explain.

How many times does a human heart beat during a person’s lifetime? How many gallons of blood does it pump? (Estimate that the heart pumps 50 cm3 of blood with each beat.)

A medical technician is trying to determine what percentage of a patient’s artery is blocked by plaque. To do this, she measures the blood pressure just before the region of blockage and finds that it is 1.20×104Pa, while in the region of blockage it is role="math" localid="1668168100834" 1.15×104Pa. Furthermore, she knows that blood flowing through the normal artery just before the point of blockage is traveling at 30.0 cm/s, and the specific gravity of this patient’s blood is 1.06. What percentage of the cross-sectional area of the patient’s artery is blocked by the plaque?

Starting from a pillar, you run 200 m east (the +x-direction) at an average speed of 5.0 m/s and then run 280 m west at an average speed of 4.0 m/s to a post. Calculate (a) your average speed from pillar to post and (b) youraverage velocity from pillar to post.
