Why do we require Latitudes and Longitudes? What are the major latitudinal belts? 2. What are Time Zones? 3. How many total time zones are there on the planet earth? 4. How many time zones are there for USA (not just the continental US) and then compare the times of all different time zones of USA with respect to 9:00 a.m. in Atlanta, GA

Hi please help with this question thank you I just can't seem to work it out even with the given formulas. Thanks! also, I have tried these but they seem to be incorrect, or maybe parts of the calculation may be incorrect since when I submit these all together and I can't really work out where I am going wrong: sigma 1 = 73.31 MPa theta 1 = 56.87 degrees sigma 2 = 18.68 MPa theta 2 = 146.875 degrees Tmax in plane = 27.315 MPa theta s = 101.87 degrees

1. The development of thermodynamics since the 17th century, which was pioneered by the invention of the steam engine in England, and was followed by thermodynamic scientists such as Willian Rankine, Rudolph Clausius, and Lord Kelvin in the 19th century. explain what the findings or theories of the 3 inventors are! Please answer fast max 25-30.minutes thank u

Cin:3 Please whow full work it will help alot

Hello. Can you please help answer the question shown in the photo? It is a 3-part question which I have attempted many times. I was able to calculate the correct answer for part 2, but part 1 and part 3 still says I am incorrect. Please show how to properly solve the problem. The topic is heat transfer. Thank you.

1. The wheel starts rotating from rest, 2) if its angular velocity Was a function of angular position 0 is W=0.1-0², where O is in radian, and its radius ris 0.2 m, what is the magnitude of the angular acceleration (in rad/s?) of the wheel after the wheel has turned 1.1 revolution(s) from rest. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point. P

According to this flowchart, the Sun will become A. hotter and brighter in stage 2, then cooler and dimmer in stage 3 B. cooler and dimmer in stage 2, then hotter and brighter in stage 3 C. hotter and dimmer in stage 2, then cooler and brighter in stage 3 D. cooler and brighter in stage 2, then hotter and dimmer in stage 3

Please provide equations that you are using so I can follow along and learn how to do this and include conversions and units. In Jamestown, NY, a coal power plan consumes coal at a rate of 80 tons/hr.  When coal burns, it generates approximately 30,000 kJ for every kg of coal burned.  The cooling course for the plant is the nearby Chadakoin River nearby and, by code, the power plant cannot reject more than 13.19 x 109 MJ into the river annually.  Determine the maximum average power output of this plant and it's maximum thermal efficiency.  To check your work, enter the efficiency, as a decimal, in the box provided.
