Answer:
2.7 J
Explanation:
The energy of one photon is given by
where
h is the Planck constant
f is the frequency
For the photons in this problem,
So the energy of one photon is
The number of photons contained in 1.0 mol is
(Avogadro number)
So the total energy of 
photons contained in 1.0 mol is
Answer:
the heat of the light.
Explanation:
no matter the light, there's always heat being produced from it. and heat makes liuqid rise
1).
Time = (distance) / (speed)
Time = (1000 meters) / (331 m/s)
<em>Time = 3.02 seconds</em>
2).
Acceleration = (change in speed) / (time for the change)
Change in speed = (second speed) - (first speed)
Change in speed = (50 m/s) - (20 m/s) = 30 m/s
Acceleration = (30 m/s) / (5 seconds)
<em>Acceleration = 6 m/s²</em>
Answer:
With more air is more buoyancy. When deflated or released the scuba diver is less buoyant.
Explanation:
The compensator is a Buoyancy control device that has an inflatable air bladder.When we have more air out into the inflatable bladder, then one is more buoyant. If the air is released from the bladder, then one is less buoyant. We add air through an air inflation valve. Air is also then released using air-deflation valves.
Buoyancy can be defined as an upward force which is exerted on an object that is fully or partially immersed in water
when one is less buoyant than water, it means that the upward pressure is more than the downward pressure of that person and his equipment. Then he will float. In a case of negative buoyancy, we have downward pressure of this person and his equipment to be more than the upward pressure of the water. Then sinking will happen.
