Answer:
When the metal wire in an incandescent lightbulb glows when the light is switched on and stops glowing when it is switched off, this is an example of resistance, which provides light and heat.
Explanation:
Lets write again formula for determening Ann's performance.
P = 70.443 + 4,885*t
where t is in hours. This is equation with P(t) which means that P only depends on variable t. If we express t=2.6 in formula we will find her expected performance.
P = 83.144
Now, since it says that she scored 16 points less than expected we need to find value of P-16
P - 16 = 67.144
After round we get that the answer is 67
Answer:Reducing mass i.e. water
Explanation:
Frequency For given mass in glass is given by

where k =stiffness of the glass
m=mass of water in glass
from the above expression we can see that if mass is inversely Proportional to frequency
thus reducing mass we can increase frequency
The frequency of the 10th harmonic is 800 Hz
Explanation:
The frequency of the nth-harmonic for the standing waves in a string is given by the equation

where
is the fundamental frequency of the string
In this problem, we are given the frequency of the 3rd harmonic:

Which can be rewritten in terms of the fundamental frequency

So we find
:

Now that we have the fundamental frequency, we can find the frequency of the 10th harmonic, with n = 10 :
