Wavelength = speed / frequency = 340 / 17000 = 0.02 m
the amount of heat need is 71060 Joules
ExplanationThe equation for the amount of heat needed to increase the temperature of water is as follows:

where E is the amount of heat
C is the specific heat capacity of water having a standard value of 4180 J/kg*K
T is the final ans initial temperature in kelvin
m is the mass
so
Step 1
given

a) convert the temperature into kelvin

now, replace in the formula

therefore, the amount of heat need is 71060 Joules
I hope this helps you
Answer:
It will.
Explanation:
For a circuit to function properly, everything has to be connected. As the diagram shows that everything is connected and there are no gaps, it will light.
Answer:
6.25 mph
Explanation:
You would divide 25 by 4 to get the average miles per hour.
Answer:
56°
Explanation:
Brewsters angle can be simply derived from
n1sin theta1= n2sintheta2= n2costheta1
because the reflected light will be 100% polarized if it is reflected at an angle 90o to the refracted light. Hence, Brewsters angle is
Tan theta= n2/n1
1.66/1.11= 1.495
Theta = 56°
