- Which of the following describes a spurious relationship between X, Y, and Z? Select one: a. Z causes X, which causes Y b. Z has no effect on the relationship between X and Y c. Z causes both X and Y d. X causes Z, which causes Yarrow_forwardThe relationship between a temperature in degree Celsius (C) and In kelvins (K) is given by K = C + 273. What is Celsius temperature for a temperature of 10 kelvins?arrow_forwardThese are the functions in Q1 that the question in the image asks for (a) f(x,y)=πx y .(b) f(x,y)=cos(x2 +y2) (c) f(x,y)=e2xcosyarrow_forward

What rangedoes this correspond to on the Fahrenheit scale? [Note: Fahrenheit (F) and Celsius (C)temperatures satisfy the relation C 59 1F 322 .]arrow_forwardI do not understand for part D how Z = 0.385arrow_forward
- A roast turkey is taken from an oven when its temperature has reached 185 degrees F and is placed on a table in a room where the temperature is 75 degree F. a) if the temperature of the turkey is 150 degree F after half an hour, what is the temperature after 35 minutes? b) when will the turkey have cooled to 105 degree F?arrow_forwardTsunami Waves and BreakwatersThis is a continuation of Exercise 16. Breakwaters affect wave height by reducing energy. See Figure 5.30. If a tsunami wave of height H in a channel of width W encounters a breakwater that narrows the channel to a width w, then the height h of the wave beyond the breakwater is given by h=HR0.5, where R is the width ratio R=w/W. a. Suppose a wave of height 8 feet in a channel of width 5000feet encounters a breakwater that narrows the channel to 3000feet. What is the height of the wave beyond the breakwater? b. If a channel width is cut in half by a breakwater, what is the effect on wave height? 16. Height of Tsunami WavesWhen waves generated by tsunamis approach shore, the height of the waves generally increases. Understanding the factors that contribute to this increase can aid in controlling potential damage to areas at risk. Greens law tells how water depth affects the height of a tsunami wave. If a tsunami wave has height H at an ocean depth D, and the wave travels to a location with water depth d, then the new height h of the wave is given by h=HR0.25, where R is the water depth ratio given by R=D/d. a. Calculate the height of a tsunami wave in water 25feet deep if its height is 3feet at its point of origin in water 15,000feet deep. b. If water depth decreases by half, the depth ratio R is doubled. How is the height of the tsunami wave affected?arrow_forward
