Answer:
A
Explanation:
I think the answer would be A
wrong. If its for the study island its potential energy only.
Answer: 1.06 kg
Explanation:
Density is defined as the mass contained per unit volume.

Given :
Density of mercury = 
volume of cylinder = volume of mercury = 
where r = radius of cylinder = 
h= height = 25.0 cm
Putting in the values we get:
volume of mercury =
(1kg=1000g)
Thus mass of mercury required to fill a hollow cylinder having an inner diameter of 2.00 cm to a height of 25.0 cm is 1.06 kg.
The wavelength that represented photons is at <span>lambda = 376.4 nm.
The wavelength with the higher energy is at </span><span>lambda - 372.1 nm.
The longer wavelength is, of course, </span> at lambda 376.4 <span>nm.
The wavelength with the higher frequency is </span> 376.4 <span>nm.</span><span>
