Answer: In convection, there is a transfer of heat due to the bulk movement of molecules within the fluid. It affects our atmosphere, layers of earth and our ocean due to the temperature difference.
Explanation:
Convection is a transfer of heat due to bulk movement of molecules within the fluid.
Convection affects our atmosphere. There is a temperature difference in the atmosphere. Warmer air rises up in compare to the cooler air.
Convection affects our layers of earth. It is limited to troposphere. Due to the high transmission of clear sky to bulk incident energy from sun, troposphere is subjected to convection.
Convection affects our oceans. There will be temperature difference in the ocean water. When the water of ocean heats up then it becomes less dense.
Answer: Current needed, mA 20 Voltage needed, V AC 6
Explanation: An electric gradient (or field) can exist that is analogous to the situation described above for step and touch potentials. The situation is more complex to analyze in the water because a person in the water assumes different postures and orientations in 3 dimensions (up, down, and sideways—north, south, east, and west). The transthoracic and translimb voltages will vary as the person moves in relation to the orientation (direction) of the electric field.
Answer:
hold up nvm Reaction with oxygen
Explanation:
We don't see any circuit diagrams.
This worries us for a few seconds, until we realize that we don't know anything about the experiment described in the problem either, so we don't have to worry about it at all.
The equation for range is:
R = v₀²sin(2θ)/g
To find the maximum R, differentiate the equation and equate to zero. The solution is as follows:
dR/dθ = (v₀²/g)(sin 2θ)
dR/dθ = (v₀²/g)(cos 2θ)(2) = 0
cos 2θ = 0
2θ = cos⁻¹ 0 = 90
θ = 90/2
<em>θ = 45°</em>
