Answer:
the pilot should head the plane towarrds south- west
Solution:
The airspeed of the airplane, v = 280 km/h
The velocity of the wind, v' = 52 km/h South-west
Angle,
Now, measured angle in the clockwise direction from North:
Now,
south- west
Answer:
C
Explanation:
the correct answer is c) Pre Schematic.
It is in the Pre-schematic stage of development that the children learn to draw human figures by sketching a circle with dangly lines for legs. It remains till the age of six. After pre schematic stage comes the schematic stage, where in children can draw complex structures.
Answer:
total magnification = 400 X
Explanation:
given data
ocular lens = 10 X
objective lens = 40 X
to find out
total magnification
solution
we know that total magnification is express as
total magnification = Objective magnification × ocular magnification .................1
put here value we get
total magnification = 10 × 40
total magnification = 400 X
In optics, chromatic aberration (CA, also called achromatism, chromatic distortion, and spherochromatism) is an effect resulting from dispersion in which there is a failure of a lens to focus all colors to the same convergence point. It occurs because lenses have different refractive indices for different wavelengths of light.
Given data:
* The height of the balcony is 52.8 m.
* The initial velocity of the coin is zero.
Solution:
By the kinematics equation, the time taken by the coin to land on the fountain is,
where H is the height, g is the acceleration due to gravity, u is the initial velocity, and t is the time taken,
Substituting the known values,
