Explanation:
The value of g at the Earth's surface is

where G is the gravitational constant
M is the Earth's mass
is the Earth's radius
Solving the formula for M, we find the value of the Earth's mass:

The Earth's volume is (approximating the Earth to a perfect sphere)

So, the average density of the Earth is

Shield volcanoes are formed by lava flows of low viscosity.
Answer:
Bromine is heavier than air in terms of its atomic weight. Look at the periodic table bromine is lower than oxygen, nitrogen, etc. bromine in its gaseous phase will still float in air. <em>This is due to the fact that gaseous bromine takes up a wide volume of space while having little mass.</em>
Diffraction, this refers to the various phenomena that occur when a wave encounters an obstacle or a slit, which is what happens when an ultrasound is being processed
