Given,
Radius of curvature of concave mirror = 1.6m
We know that ,
Focal length = radius/2
Hence ,
Focal length of concave mirror = radius of concave mirror /2
=> F = 1.6/2
=> F = 0.8m
Hence the focal length of concave mirror is 0.8 m
Answer:
Worldwide Radio Communication
Explanation:
The ionosphere is important because it is through the ionosphere that world wide radio communication is possible.
Nitially the flame produces radiation<span> which heats the tin can. The tin can then</span>transfers heat<span> to the water </span>through<span> conduction. The hot water then rises to the top, in the convection process. </span>
Sunlight, because it provides a source of energy is the answer because plants also provide a food source (please put as brainliest answer)
Answer:
Plasma can be artificially generated by heating a neutral gas or subjecting it to a strong electromagnetic field to the point where an ionized gaseous substance becomes increasingly electrically conductive.
