The answer is B frequency. When frequency increases more wave crests pass a fixed point each second. That means the wavelength shortens. So, as frequency increases, wavelength decreases
Positive acceleration . . .
Acceleration in the direction you decided to call the positive direction
when you started working on the problem.
Negative acceleration . . .
Acceleration in the direction opposite to the one you decided to call
the positive direction when you started working on the problem.
g≈10 m/s²
F=G=mg=65*10=650 N
L=F*h=650*7=4550 J
P=L/t=>t=L/P=4550/300=15.16 s
Two thermometers, calibrated in celsius and fahrenheit respectively, are put into a liquid. the reading on the fahrenheit scale is four times the reading on the celsius scale. the temperature of the liquid is:
