Answer:
Explanation:
Given
side of square shape 
Electric flux 
Permittivity of free space 
Flux is given by
where E=electric field strength
A=area
=Angle between Electric field and area vector
and Electric field by a uniformly charged sheet is given by
where 
=charge density
Explanation:
Mass of the Earth is equal to,
Any number can be written in the form of scientific notation as :
m is the real number
n is any integer
Mass of the earth can be written in the form of scientific notation as :
Here,
m = 5.97
n = 24
Hence, this is the required solution.

12:A) Sound needs a medium to travel
13:D) Just like with cupped hands
Answer: SG = 2.67
Specific gravity of the sand is 2.67
Explanation:
Specific gravity = density of material/density of water
Given;
Mass of sand m = 100g
Volume of sand = volume of water displaced
Vs = 537.5cm^3 - 500 cm^3
Vs = 37.5cm^3
Density of sand = m/Vs = 100g/37.5 cm^3
Ds = 2.67g/cm^3
Density of water Dw = 1.00 g/cm^3
Therefore, the specific gravity of sand is
SG = Ds/Dw
SG = (2.67g/cm^3)/(1.00g/cm^3)
SG = 2.67
Specific gravity of the sand is 2.67
A and c are correct I think, because as the sun is so hot anyone wanting to test it would die. Google it to double check ❤ good luck with whatever you're doing
