Answer:
<h2>mass = 10.72 g</h2>Explanation:
Density of a substance can be found by using the formula
Making mass the subject we have
From the question
Density = 2.70 g/cm³
We assume that the aluminum is a cuboid
and volume of a cuboid is given by
Volume = length × width × height
length = 5.3 cm
width = 0.32 cm
height = 2.34 cm
Volume = 5.3 × 0.32 × 2.34 = 3.97 cm³
Substitute the values into the above and solve for the mass
We have
mass = 2.70 × 3.97
We have the final answer as
<h3>mass = 10.72 g</h3>Hope this helps you
Answer: Wavenumber of the radiation emitted is
Explanation:
The relationship between wavelength and energy of the wave follows the equation:
where,
E = energy of the radiation =
h = Planck's constant =
c = speed of light =
= wavelength of radiation = ?
Putting values in above equation, we get:
Thus wavenumber of the radiation emitted is
