Answer:
In physics, a virtual particle is a transient quantum fluctuation that exhibits some of the characteristics of an ordinary particle, while having its existence limited by the uncertainty principle. The concept of virtual particles arises in perturbation theory of quantum field theory where interactions between ordinary particles are described in terms of exchanges of virtual particles. A process involving virtual particles can be described by a schematic representation known as a Feynman diagram, in which virtual particles are represented by internal lines.

im 15 and i live in the u.s. (not for long tho. moving to Norway cause they got a better economy and support the gay.)
Answer:
Focal length of the mirror will be 660 mm
Explanation:
We have given that sunlight is focused at a distance of 330 mm in front of mirror
So focal length f = 330 m
We have to find the radius of curvature
Radius of curvature is double the focal length
So radius of curvature = 2× focal length = 2×330 = 660 mm
So focal length of the mirror will be equal to 660 mm
Answer:
The power to maintain constant temperature is 18.56kW
Explanation:
Given
Required
Determine the power to maintain constant temperature
The power to maintain a constant temperature is the difference between heat loss and gain
i.e.
This gives:
Convert Btu/h to kW
So:
<em>Hence;</em>
<em>The power to maintain constant temperature is 18.56kW</em>
A.) The higher the altitude, the colder the climate will be
B.) Areas near the equator have warmer climates than areas for form the equator.
D.) Winds that blow inland from oceans or large lakes contain a lot of water vapor that will cause precipitation.
C.) Monsoons.
Technically, displacement is the "shortest" distance between any two points. If you say displacement is greater than distance, you will contradict the above statement. Displacement is always less than or equal to distance. Note that distance is a scalar whereas displacement is a vector. :)
