Apparent depth is dangerous for swimmers because
<span> When you look vertically downwards into a </span>swimming<span> pool full of water the bottom seems closer than it. </span>If the pool is really deep and it doesn't look deep to you that's not good cuz if you don't know how to swim in deep water you might drown.
Hope this helps ;)
Answer:
I will explain the concept of magnetic field and how it can be calculated.
Explanation:
The formula for magnetic field at the center of a loop is given as
B = μI / 2R
where B is the magnetic field
R is the radius of the loop
I is the current
and μ is the magnetic permeability of free space which is a constant 4π × newtons/ampere²
If the magnetic field at the center of the loop is 0, then μI = 0
I = 0 which means there will be no current flow in the loop.
Simplicity of conducting the study is to archival research; as ability to test large numbers participants is to survey.
Answer: 8400 J
Explanation:
The formula referenced in the question is:
Where:
is the thermal energy
is the mass of the water sample
is the specific heat capacity of water
is the variation in temperature
Solving:
This is the thermal energy released
The translation kinetic energy would be
1/2mv^2 thus
1/2* 7 * 16
which comes to 56
