Find the angle between the vectors u = (–5, 1, 3) and v = (–2, 1, –2).

1. Begin in the west and move across the map to the east, briefly explaining why the actual 16 degrees Celsius isotherm deviates from the hypothetical.

In this experiment, the signal generator was set so that the frequency meter showed a reading of 1,803 Hz. The microphone was moved to a distance from the speaker so that the oscilloscope displayed a straight diagonal line. This position was of the microphone was recorded as the initial position, or beginning of a wavelength. The microphone was then moved farther in the same direction until the oscilloscope displays the same horizontal line. This position was recorded as final position, or the end of the wavelength. The distance between the two positions represents one wavelength for this frequency. This was repeated for frequencies of 2,402 Hz, 3,002, Hz, 3,602 Hz, and 4,201 Hz.

T= 40ms, I figured this by guessing cause I could not find any information on how to calculate. So I used the equation for t and plugged in different numbers until I got the 10ms that was already given in the table. t= T x 0/360= 40ms x 90/360= 0.01 x 10^-3= 10ms

2) A boat can move at 30 km/h in still water. How long will it take to move 12 km upstream in a river flowing 6.0 km/h?

Ellen’s train should travel faster than 198.88mph but slower than 200.11mph and in 2.5 hours Ellen’s train would have traveled more than 497.2mi but less than 500.28mi.

A light ray enters a rectangular block of plastic at an angle θ1 = 45.0◦ and emerges at an angle θ2 = 76.0◦ as shown. (a) Determine the index of refraction of the

Perform the following metric conversions. For each conversion indicate which physical quantity is being measured. (For example, 2 s is a measurement of time.)

After doing this problem, I found that I am very comfortable using the kinematic equation of vf = v​i​​+at, when I use this equation I find that I always get the right answer for the problem, which is great, and I have no further questions to help me understand this

An airplane is flying to a city due west from its current location. If there is a slight wind blowing to the southwest, in what direction must the plane head (that is, in what direction must it point)? Explain your answer using a diagram.

J) The altitude decreased by 13 degrees since the previous observation, and the azimuth increased by 13 degrees.

The magnitude of the forces exerted in the horizontal and vertical directions can be calculated using trigonometry. The total magnitude of the force multiplied by the cosine of its angle with the horizon will calculate the horizontal force. Conversely, the total magnitude of the force multiplied by the sine of its angle with the horizon will calculate the vertical force.
