The mass of lead = 22,939 kg
<h3>Further explanation</h3>
Given
mass alcohol=1600 kg
The density of lead =11300kg\m³ and density of alcohol=790kg\m³
Required
mass of lead
Solution

the volume of lead=volume of alcohol=2.03 m, so the mass of lead :

Answer:
Energy is inversely proportional to wavelength.
Explanation:
The amount of energy, E, a wave carries is given as:
E = hf
where h = Planck's constant and f = frequency of the wave
Frequency and wavelength are related by the equation:
c = λf
=> f = c/λ
where λ = wavelength
Therefore, energy is:
E = hc/λ
This shows that energy is inversely proportional to wavelength. As wavelength increase, energy decreases and vice versa.

Answer:
It is a copy of an object and appears to be coming from behind the mirror.
Explanation:
- The plane mirror has a flat surface, where of its surface is polished to reflect the light.
- The plane mirror shows the image as the same size of the object.
- The image produced by the plane mirror is virtual and erect.
- But the orientation of the image formed changes the left and right.
- Hence,the image appears to be coming from behind the mirror.
