Answer: magnitude = 5 and angle = 160°
Explanation:
A vector has magnitude 5 and angle -20°
A vector can be written in terms of its components as :
using trigonometry identity:
sin θ = -sin ( 180 + θ )
cos θ = - cos (180 + θ)
Thus, we can write the same vector as:
Magnitude
Thus, the magnitude would be A = 5 and angle = 180+θ= 180-20 = 160°
B) A virtual image is produced if the object is on the focal point, the image is inverted, enlarged and on the opposite side of the lens from the object.
C) A virtual image is produced if the object is between the focal point and the lens, the image will be upright, enlarged and on the same side of the lens
as the object.
D) A virtual image is produced if the object is between the focal point and the
lens, the image will be upright, reduced and on the opposite side of the
lens from the object.
A virtual image is produced if the object is between the focal point and the lens.
A converging lens is a lens that can produce both real and virtual images depending on the position of the object.
A virtual image is produced if the object is between the focal point and the lens, the image will be upright, enlarged and on the same side of the lens as the object.
