Net convective heat transfer loss rate (gnet)
Gnet = 2h, A (Ts - T∞)
=2(4.51) (0.001) (25)
Gnet = 0.2250 W.
There are two types of convection: natural convection and forced convection. Natural convection is caused by differences in the density of liquids due to differences in temperature (eg "hot air rises"). Global atmospheric circulation and local weather phenomena (including wind) are due to convective heat transfer.
Newton's Law of Cooling is a widely used equation for calculating both forced and natural net convective. The formula for Newton's Law of Cooling is Q = h A ΔT. Equation parameters and their typical US and SI.

Well,
The tiny, solid particles you find in the atmosphere serve as cloud condensation nuclei.
You see, in order for water to condense, the water must have a direct object, grammatically speaking.
Your answer: Tiny, solid particles in the atmosphere play a role in cloud formation by providing the object upon which water may condense to form clouds.
Answer:
Explanation:
At a location above the halfway point between the window and the ground
Bacteria get rid of waste through their semi-permeable membrane by diffusion. The waste is pushed out of the organism in the form of liquid or gas. The waste released by bacteria is usually toxic and is what makes people sick.
Answer:
The value is 
Explanation:
Generally the relative speed at which you are moving with respect to the person ahead of you is mathematically represented as
substituting 1.05 m/s for 
and 2.75 m/s for 
So
=> 
Generally the distance by which the person is ahead of you is mathematically represented as
substituting 18.5 s for 
=>
