D - you divide 200/2 to get the average (change in y over change in x)
Answer:
1.2×10⁶ Hz
Explanation:
Applying,
v = λf............. Equation 1
Where v = speed of wave, λ = wavelength, f = frequency.
make f the subject of the equation
f = v/λ............... Equation 2
From the question,
Given: v = 3.0×10⁸ m/s, λ = 2.5×10² m
Substitute these values into equation 2
f = 3.0×10⁸/2.5×10²
f = 1.2×10⁶ Hz
Answer:
A carpet transfers more energy to heat than the floor, I believe.
Explanation:
There is more friction on the carpet creating more heat and energy loss. Potential energy is gained from being at a higher elevation.
