Chapter 1, Problem 49EAP
Earth Rotation Speed. Mathematical Insight 1.3 shows how to find Earth’s equatorial rotation speed. To find the rotation speed at any other latitude, you need the following fact: The radial distance from Earth’s axis at any latitude is equal to the equatorial radius times the cosine of the latitude. Use this fact to find the rotation speed at the following latitudes. (Hint: When using the cosine (cos) function, be sure your calculator is set to recognize angles in degree mode, not in radian or gradient mode.)
a. 30°N b. 60°N c. your latitude

Three long, straight wires are mounted on the vertices of an equilateral triangle as shown in the figure. The wires carry
currents of I₁ = 3.50 A, I2 = 5.50 A, and I3 = 8.50 A. Each side of the triangle has a length of 34.0 cm, and the point (A)
is located half way between (11) and (12) along one of the sides. Find the magnitude of the magnetic field at point (A).
Solve in Teslas (T).

Number
There are four charges, each with a magnitude of 2.38 μC. Two are positive and two are
negative. The charges are fixed to the corners of a 0.132-m square, one to a corner, in such a way
that the net force on any charge is directed toward the center of the square. Find the magnitude
of the net electrostatic force experienced by any charge.

Measurements and Linear Regression 1.1 Introduction The objective of this lab assignment is to represent measurement data in graphical form in order to illustrate experimental data and uncertainty visually. It is often convenient to represent experimental data graphically, not only for reporting results but also to compute or measure several physical parameters. For example, consider two physical quantities represented by x and y that are linearly related according to the algebraic relationship, y=mx+b, (1.1) where m is the slope of the line and b is the y-intercept. In order to assess the linearity between y and x, it is convenient to plot these quantities in a y versus x graph, as shown in Figure 1.1. Datapoints Line of regression Figure 1.1: Best fit line example. Once the data points are plotted, it is necessary to draw a "best fit line" or "regression line" that describes the data. A best fit line is a straight line that is the best approximation of the given set of data, and…arrow_forward
