The relationship between frequency and wavelength for an electromagnetic wave is

where
f is the frequency

is the wavelength

is the speed of light.
For the light in our problem, the frequency is

, so its wavelength is (re-arranging the previous formula)
Answer:
The science of the conversions between heat and other forms of energy.
Explanation:
Answer: 70m
Explanation:
Given, 2 skaters, one with a mass of 60kg.
Another 75kg.
Distance is 14m.
Assuming the system centre if mass does not change, both skaters would meet at the centre of the mass
let the 60kg skater be xm away from the centre, then, the 75kg skater would be (14 - x)m away from the centre too
m1x + m2(14 - x) = 0
m1x + 14m2 - m2x = 0
60x + 14*75 - 75x = 0
60x - 75x + 1050 = 0
-15x + 1050 = 0
15x = 1050
x = 70
Thus, the distance the 65kg skater moves is 70m
Energy change = -303050 J
Explanation:
the heat energy Q is given by the formula
Q= m C ΔT
m= mass of water=1.25 Kg
C= specific heat of water= 4180 J/Kg °C
ΔT= change in temperature =55-113= -58°C
Q= 1.25 (4180) (-58)
Q=-303050 J
Negative sign shows that the energy is released or lost.
