The image formed by a concave mirror with the object placed at the center of curvature is real inverted and formed at the center of curvature. Using the ray diagram a ray from the top of the object to the mirror through f then reflected parallel to the principal axis,then the ray through the center of curvature reflected through the same point both intersect at a plane through center curvature and perpendicular to the principal axis. The point of intersection forms the top of the image and the center of curvature forms the bottom. Therefore, the correct choices are : real and inverted
Answer:
The cellphone's main purpose is to keep people connected, regardless of the distance that separates them. Cellphones, much like traditional phones, allow you to place and receive calls.
Explanation:
THe first one and the third one!!
Answer:
50 degrees
Explanation:
Usually in physics in solving such questions refractive index of air is taken as 1.00 (n=1.00) by assuming that air is a vacuum. Hence, the light ray passes from water to air at an angle of incident of 40 degrees, it means that it has angle of 50 degrees to the normal line.
"Watch" . . . atmospheric conditions exist that could
produce tornados, but none have been seen yet.
"Warning" . . . tornados have formed and have been seen.
