Order of magnitude is usually written as 10 to the nth power. The n represents the order of magnitude. If you raise a number by one order of magnitude, you are basically multiplying that number by 10. If you decrease a number by one order of magnitude, you are basically multiplying that number by 0.1.
Answer:
u = 6.667 cm
Explanation:
given,
Focal length of the concave mirror, f = 20 cm
magnification factor = 1.5
we know,
v is the distance of the image
u is the distance of the object
v = -1.5 u
Using mirror formula
u = 6.667 cm
distance of the person from the mirror is equal to 6.667 cm.
Answer: B. Only the mass of the planet
Explanation:
the confusion on the concepts of mass and weight arises from the fact that the acceleration due to gravity is more or less constant in any place on the Earth's surface, thus the weight of an object is directly proportional to its mass. hope it helps <3

Answer:
the higher the frequency the shorter the wave length
Explanation:
because all light waves move through a vacuum at same speed the number of wave crests passing by a given point in one second depends on the wavelength
