This is an example of how weathering affects the Earth's surface. No-Till Farming and Contour Farming are two examples of preventing soil erosion.</span>
The answer would be C since metals have electrons that help in heating up the metal
Kinetic energy has a formula
Kinetic energy = 1/2 * mass * velocity ^2
When sounds at two different frequencies are combined,
two new sounds are created ... at the sum and difference
of the original frequencies.
Combining two sounds at 490 Hz and 488 Hz creates
beats at 978 Hz and 2 Hz.
The fluttering "wah wah" effect of the 2 Hz beat is much more
noticeable than the new sound at 978 Hz.
