(a) On a piece of graph paper, draw the vector f→=<-2,4,0>, putting the tail of the vector at <-3,0,0>.Label the vector f→.

Short Answer

Expert verified

The graph of Vector f→=-2,4,0with the Vector tail = -3,0,0

Step by step solution

01

Given Information

Vectorf→=-2,4,0

Vector tail =-3,0,0

02

Vector

The vector has three components. These three components are the unit cut by the vector on x, y and z axis. The vector components can be represented by the following manner.

Let the vector is r, then the vector component of the vector r will be,

r→=rx,ry,rz

Where, rxisxaxisunit,ryisyaxisunit,rziszcomponentunit.

Question: The following questions refer to the circuit shown in Figure 18.114, consisting of two flashlight batteries and two Nichrome wires of different lengths and different thicknesses as shown (corresponding roughly to your own thick and thin Nichrome wires).


The thin wire is 50 cm long, and its diameter is 0.25 mm. The thick wire is 15 cm long, and its diameter is 0.35 mm. (a) The emf of each flashlight battery is 1.5 V. Determine the steady-state electric field inside each Nichrome wire. Remember that in the steady state you must satisfy both the current node rule and energy conservation. These two principles give you two equations for the two unknown fields. (b) The electron mobility

in room-temperature Nichrome is about 7×10-5(ms)(Ns). Show that it takes an electron 36 min to drift through the two Nichrome wires from location B to location A. (c) On the other hand, about how long did it take to establish the steady state when the circuit was first assembled? Give a very approximate numerical answer, not a precise one. (d) There are about 9×1028mobile electrons per cubic meter in Nichrome. How many electrons cross the junction between the two wires every second?

At a certain instant a particle is moving in the +xdirection with momentum +8kg.ms. During the next 0.13sa constant force acts on the particle, with Fx=-7Nand Fy=+5N. What is the magnitude of the momentum of the particle at the end of this0.13s interval?

Two metal rods are made of different elements. The interatomic spring stiffness of element A is three times larger than the interatomic spring stiffness for element B. The mass of an atom of element A is three times greater than the mass of an atom of element B. The atomic diameters are approximately the same for A and B. What is the ratio of the speed of sound in rod A to the speed of sound in rod B?

Because the change of the momentum is equal to the net impulse, the relationship of momentum itself to the net force is somewhat indirect, as can be seen in this question. An object is initially moving in the + x direction with a magnitude of momentum p, with a net force of magnitude F acting on the object in either the + x or - x direction. After a very short time, say whether the magnitude of the momentum increases, decreases, or stays the same in each of the following situations:

a) the net force acts in the + x direction and F is constant.

b) the net force acts in the + x direction and F is increasing.

c) the net force acts in the + x direction and F is decreasing.

d) the net force acts in the - x direction and F is constant.

e) the net force acts in the - x direction and F is increasing.

f) the net force acts in the - x direction and F is decreasing.

A driver starts from rest on a straight test track that has markers every0.1 Km. The driver press on the accelerator for the entire period of the test holds the car at constant acceleration. The car passes the0.1 Kmpost at 8 sec after starting the test. (a) What was the car’s acceleration? (b) What was the cars speed as it passed the 0.1 Km post? (c) What does the speedometer read at the post? (d) When does the car pass the 0.2 Km post?
