Answer: Wavelength is related to light and also related to energy. The shorter the wavelengths and the higher the frequency corresponds with greater energy. So the longer the wavelengths and lower the frequency results in lower energy. The energy equation is E = hν.
Unequal opposite forces.
(They're unbalanced.)
B. Yard
the other answers C. & D. are metric A is a unit of temperature
Answer:
(a) 49.0 mm
Explanation:
#First we need to calculate the height of the mercury arm:
Reduced pressure is 715.7torr, Initial Pressure is 797.3torr, Required pressure is:
The difference in the two arms will give the pressure difference between the gas placed in the flask attached to an open-end mercury manometer.

Hence the height of the mercury in the arm is 49.00mm
1). D. Combined Gas Law
3.) D. Pressure and temperature
4.) C. Boyles law
