The wind-chill index is modeled by the function W − 13.12 1 0.6215T 2 11.37v 0.16 1 0.3965Tv 0.16 where T is the temperature sin 8Cd and v is the wind speed sin kmyhd. The wind speed is measured as 26 kmyh, with a possible error of 62 kmyh, and the temperature is measured as 2118C, with a possible error of 618C. Use differentials to estimate the maximum error in the calculated value of W due to the measurement errors in T and v.

Awater-filled u-tube manometer is used to measure the pressure inside a tank that contains air. the water level in the u-tube on the side that connects to the tank is 5 ft above the base of the tank. the water level in the other side of the u-tube (which is open to the atmosphere) is 2 ft above the base. determine the pressure within the tank.

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?

Your science teacher brings in a speaker to talk to your class about climate change. during the session, students ask a few questions. which questions are related to the current evidence on climate change
