Answer:
Either temperature or energies but I am pretty sure its temperature
Explanation:
Moles x Mol mass = mass.
<span>Having looked it up, the mol.mass of U-238 is 238.03g/mol. </span>
<span>7.50 moles x 238.03g/mol. = 1,785.23g/mol</span>
Answer:
A. loses an electron, it becomes positively charged.
The answer is C in this question.
Answer:
The minimum thickness of the Lucite plate is 0.670 μm.
Explanation:
Given that,
Wavelength = 650.0 nm
Index of refraction = 1.485
We need to calculate the minimum thickness of the Lucite plate
Using formula of thickness


Where, n = Index of refraction
= wavelength
Put the value into the formula


Hence, The minimum thickness of the Lucite plate is 0.670 μm.
