Step-by-step explanation:
The sun subtends an angle 
rad
Angular velocity equation is 
where 
is angular velocity and t is time.
Earth spins at a rate of :
rad/s
Isolating time (t) from angular velocity equation gives:
Answer:
The percent error based on the average measurements is 0.8%.
Step-by-step explanation:
The standard equation for percent error is [(original - actual)/original} x 100. The original amount is 100 degrees celcius. Your average measurement can be found by adding the three temperatures together and dividing by the number of temperatures collected: 98.5 + 99.3 + 99.8 = 297.63/3 = 99.2. When we place our numbers into the equation and solve, we get: (100 - 99.2)/100 = 0.008 x 100 (to get our percentage) = 0.8%.
Answer:
The length of the altitude from the right angle to the hypotenuse of a right triangle is the <u>geometric</u> mean of the two segments that make the hypotenuse.
