Answer:
100,000 times
Explanation:
Luminosity is the measure of brightness of a star. It is measured by examining the radiant energy emitted by the stars per second. Rigel's radius is about 80 times that of the Sun's radius. Therefore, its luminosity is about 100,000 times the sun’s luminosity.
This one is very easy it is B position x. It is the first one you can move the rock if your trying to do it with not much force if you did Y and Z it will fly off and if you did w it will do nothing. Hope I helped just think of you doing it in real life.
Answer:
E = 37467J/mol = 37.5kJ
Explanation:
Please see attachment below.
The equation that relates two rates of reaction (Arrhenius equation) is what is used to solve this kinds of problem the equation is given as follows.
r1l2/r1= e^-E/R×(1/T2–1/T1)
Where
r1 = initial rate of reaction
r2 = final rate of reaction
E = Activation energy
T1, T2 = initial and final temperatures.
R = gas constant = 8.314J/milk
