Answer:
Explanation:
From the question we are told that:
Height
Radius
Height of water
Gravity
Density of water
Generally the equation for Volume of water is mathematically given by
Where
y is a random height taken to define dv
Generally the equation for Work done to pump water is mathematically given by
Substituting dv
Therefore
'
'
Answer:
Explanation:
Given
Temperature of Room
Area of Person
Temperature of skin
Heat transfer coefficient
Emissivity of the skin and clothes
Total rate of heat transfer=heat Transfer due to Radiation +heat transfer through convection
Heat transfer due radiation
where
Heat Transfer due to convection is given by
Answer:
How much does light bend? When light travels from air into water, it slows down, causing it to change direction slightly. This change of direction is called refraction. When light enters a more dense substance (higher refractive index), it 'bends' more towards the normal line.
Answer:
just search up a ven-diagram and then try to draw it or trace it then use it for ur question
Explanation:
Frequency = speed / wavelength
(6 m/s) / (12 m) = 0.5 Hz.
That's not infrared light.
Infrared light waves move about 50 million times faster than that, and they're only about 0.00000007 as long as that.
