Air traffic controllers give instructions called 鈥渧ectors鈥� to tell airline pilots in which direction they are to fly. If these are the only instructions given, is the name 鈥渧ector鈥� used correctly? Why or why not?

Short Answer

Expert verified

The instruction given by airline controller contained only direction.

Since themagnitude is missing, it can not be a real vector quantity.

Step by step solution

01

Scalar and Vector quantity

We need to understand what a vector and a scalar quantity are,

A vector is a way of expressing a quantity has both magnitude and direction.

A quantity defined by the magnitude as well as the magnitude's direction of action. For instance, consider the concepts of force and displacement.

Scalar quantity: Quantity that can be fully comprehended using only the magnitude value. Mass, temperature, and time are examples of scalar quantities.

02

Explanation

A vector quantity consists of magnitude and direction, but as stated in the problem, the instruction given by the airline controller contained only direction. Since the magnitude is missing, it can not be a real vector quantity.

So the name 鈥榲ector鈥� is misleading here.

So instand of giving the direction the pilot also have to give the magnitude of the vector, that is how much to north or at what degree to south.

Comparing Example 12.1 (Section 12.1) and Example 12.2 (Section 12.2), it seems that 700 N of air is exerting a downward force of on the floor. How is this possible?

At what distance above the surface of the earth is the acceleration due to the earth鈥檚 gravity 0.980 m/s2 if the acceleration due to gravity at the surface has magnitude 9.8 m/s2?

In March 2006, two small satellites were discovered orbiting Pluto, one at a distance of 48,000 km and the other at 64,000 km. Pluto already was known to have a large satellite Charon, orbiting at 19,600 km with an orbital period of 6.39 days. Assuming that the satellites do not affect each other, find the orbital periods of the two small satellites withoutusing the mass of Pluto.

Neutron stars, such as the one at the center of the Crab Nebula, have about the same mass as our sun but have a much smaller diameter. If you weigh 675Non the earth, what would you weigh at the surface of a neutron star that has the same mass as our sun and a diameter of 20km?

A jet fighter pilot wishes to accelerate from rest at a constant acceleration of to reach Mach 3 (three times the speed of sound) as quickly as possible. Experimental tests reveal that he will black out if this acceleration lasts for more than5.0s. Use331m/sfor the speed of sound. (a) Will the period of acceleration last long enough to cause him to black out? (b) What is the greatest speed he can reach with an acceleration ofbefore he blacks out?
