answer is the SECOND one on Edge
3.8 x 10^8m
the chart would’ve been helpful though.
Answer:
The image is produced 60 cm behind the mirror
The focal length of the mirror is 30 cm
Explanation:
u = Object distance = 20 cm
v = Image distance
f = Focal length
m = Magnification = 3
The image is produced 60 cm behind the mirror
The focal length of the mirror is 30 cm
The acceleration which is gained by an object because of gravitational force is called its acceleration due to gravity. Its SI unit is m/s2. Acceleration due to gravity is a vector, which means it has both a magnitude and a direction. The acceleration due to gravity at the surface of Earth is represented by the letter g. It has a standard value defined as 9.80665 m/s2.[ However, the actual acceleration of a body in free fall varies with location. (Wikipedia)
The magnitude of Alioth ( the brightest star in the big dipper ) is 1.76 and it is about 81 light years distant from Earth.
