The temperature of the water and the and the salinity of water
Answer:
the noise level of 5400 flies is equal to 84.32 dB
Explanation:
Noise made by house flies = 47 dB from the distance of 2.4 m
to calculate the noise of 5400 flies at a distance of 2.4 m.
the intensity of noise

now, I' = 5400 I₀
= 
=
= 10 ( 3.732 + 4.7 )
= 84.32 dB
hence, the noise level of 5400 flies is equal to 84.32 dB
Answer:
b) 1500N
c) to the right
Explanation:
Resultant force= 2000 -500= 1500N
Resultant force is a combination of 2 or more forces acting on an object.
Answer:

Explanation:
For n-=1 state hydrogen energy level is split into three componets in the presence of external magnetic field. The energies are,
,
,

Here, E is the energy in the absence of electric field.
And
are the highest and the lowest energies.
The difference of these energies

is known as Bohr's magneton.
B=2.5 T,
Therefore,

Now,

Therefore, the energy difference between highest and lowest energy levels in presence of magnetic field is 
Answer:
I think a tsunami
Explanation:
im not 100% sure but that would make the most sense to me hope this helped!
