What conditions must be present for germination to take place?
Air, water and warmth must be present for germination to take place.
What conditions must exist in order for energy to flow from the atmosphere to earth?
Energy
What controls the flow of hot water to the heater core on a 1993 Pontiac Sunbird?
Thermostat has to open to allow fluid flow. The supply hose to the heater core is located before the thermostat, forcing the coolant through the core even as the coolant is heating up. Water pump has to work properly to cause fluid to flow. Temperature control (lever) has to operate properly to allow fluid flow. System must not be air-bound to allow fluid flow Heater core must not be plugged

Must the flow of a compressible fluid be treated as compressible?
No, if the pressure difference results in a density change of less than thirty percent (30%) the fluid may be treated as incompressible by assuming the density of the fluid equals the average density and that the density is constant.

How pressure changes as the velocity of a fluid increases?
If we assume that the fluid we are referring to is that of an ideal fluid (incompressible and non-viscous) and is undergoing a laminar flow, we can model this problem by Bernoulli's principle and equation. Bernoulli's principle states that if the above conditions are met, the energy density of a fluid must be a constant, fixed value. This means that if the velocity of a fluid increases, other factors must decrease for the energy density of a fluid must be conserved. Bernoulli's Equation is the sum of the magnitude of the pressure, kinetic energy and potential energy of a fluid is equal to a constant. Therefore, if a velocity of a fluid increases, the kinetic energy of the fluid increases. As a result, the pressure or the potential energy must decrease. Both or only one may change; the result is dependent on the situation.
What is present when currents flow through a wire?
There must be a Electron flow in that wire. Or Energy in the form of Electric will flow in that wire. Influences that are present are Voltage, Ohms, and Amperes (amps)
What conditions must be present to frost to form?
water vapour/ cold /and a condensation medium
Explain bernoulli's principle?
In simple terms, if a fluid is flowing through a pipe, as the radius of the pipe decreases the speed of fluid flow must increase and visa-versa.
What must be present for conduction to occur?
For conduction to occur, there must be a material with free electrons, such as a metal, to allow the flow of charge. Additionally, there must be a potential difference (voltage) across the material to drive the flow of electrons. Finally, the material should be a conductor, as insulators do not allow for the flow of charge.
