Answer:
The correct wording is
- Pressure increases with the depth of the fluid.
- A plane's engines produce thrust to push the plane forward.
- A fluid can be a liquid or a gas.
- A hydraulic device uses Pascal's principle to lift or move objects.
- lift is the upward force exerted on objects by fluids.
Explanation:
1. As you go deeper into a fluid,<em> there is more of it on top of you; </em>therefore, the pressure excreted on you is greater.
2. A plane's engines pushes the air in opposite direction, which according to newton's third law, produces necessary force to move the plane forward.
3. <em>A fluid has no fixed shape,</em> and it deforms under the influence of external forces applied—liquid and gases fit into this definition.
4. Pascal's principle <em>says that pressure applied on one region of the fluid must equal pressure transmitted to another region of the same fluid</em>. This principle is used in a hydraulic device to exert forces on fluids to lift objects that would otherwise be difficult to move.
5. By definition, the upward force exerted by the fluids on objects is the lift.
The diesel engine has no ignition system. (C)
It depends on the compression of the fuel/air mixture to ignite the mixture.
This may be a big part of the reason that Diesel engines always
sound to me as if they are falling apart.
Answer:
387 volts
Explanation:
Ohm's law is used to relate voltage, current and resistance.
The formula is as follows:V = I * R
where:
V is the applied voltage (measured in volts)
I is the current flowing (measured in amperes)
R is the resistance (measured in ohm)
In the given, we have:
current (I) = 9 amperes
resistance (R) = 43 ohm
Substitute with the givens in the above formula to get the voltage as follows:
V = 9 * 43
V = 387 volts
Hope this helps :)
Answer:
1.846....hours
Explanation:
since if we divide 12 km or just 12 by 6.5 we will get this number meaning that this is how long it would take someone
Answer:
The usual method of prokaryote cell division is termed binary fission. The prokaryotic chromosome is a single DNA molecule that first replicates, then attaches each copy to a different part of the cell membrane. When the cell begins to pull apart, the replicate and original chromosomes are separated.
