Light rays change direction when they hit a mirror. The phenomenon is known as reflection. Light rays travels in a straight light. They strike the surface of the mirror at a particular angle called incident angle. It is the angle between the ray and normal at the point of contact. The rays leaves the surface making the same angle with the normal called reflection angle but in different direction. 
 
        
             
        
        
        
310.093k.
Given,
Best temperature for enzymes to work = 98.6°F
Unknown :
We need to convert the temperature from fahrenheit to kelvin.
Writing down the equation to be used in the problem's solution correctly:
K = (F x 0.55) + 255.37
F = (K - 255.37) x 1.8
The temperatures are expressed in kelvin (K) and fahrenheit (F), respectively.
There first equation would be significantly more quicker to use :
K = (98.6 x 0.555) + 255.37
 = 54.723 + 255.37
= 310.093K
➤ The activity and rate of an enzyme reaction typically increase with temperature, while a decrease in temperature slows the enzymatic reaction. Each enzyme's activity peaks at its individual optimum temperature, and it decreases above and below that point.

Answer:
6.82%
Explanation:
If 44 ±3 beats are counted in 30 seconds, twice the number of beats will be counted in 1 minute or 60 seconds, i.e. 88 beats per minute. The absolute uncertainty in 1 minute will also be twice the uncertainty in 30 seconds, so 88 ±6 beats per minute.
The percentage uncertainty can be found by below:



The percentage uncertainty can also be found for the 30 second interval



While the absolute uncertainty varies depending on the time interval, the percentage uncertainty remains the same: 6.82%
