Pretty sure it's C) condensation because all of the others required heat to be added
Answer:
Faraday's law states that electromotive force induced is proportional to the rate of change in magnetic flux
Answer:
the force pulls each other cause its just physics
Answer:
<em>The second option has a lower power output. P=30 W</em>
Explanation:
<u>Mechanical Power
</u>
It is a physical magnitude that measures the rate a work W is done over time t.
Since W=F.d
The first option means the worker will lift the box by a distance of 1.2 meters in 3 seconds by applying 250 N of force. That produces a power of
The second option requires the worker applies 75 N of force and travel a distance of 4 meters for 10 seconds, thus the power is
The second option has a lower power output
Surface tension<span> is a property of the surface of a liquid that allows it to resist an external force. for example, some objects can float on the surface of water, even though they are denser than water, and in the ability of some insectsto run on the water surface. This property is caused by cohesion of similar molecules, and is responsible for many of the behaviors of liquids.</span>
