Earth and a planetesimal collision occurred while the surface rocks of the moon were impacted, and was creating a fine dust. This is also called the giant.
Answer:
ans:
tenson(T) = 20 N
acceleration (a) = 2.86 m/s
Explanation:
T + mg = Mg
T = Mg - mg
T = g( M - m )
T = 10× ( 7-5 )
T = 20 N
again;
T = 20
Ma = 20
a = 20 / 7
= 2.86 m/s
When the object is at the focal point the angular magnification is 2.94.
Angular magnification:
The ratio of the angle subtended at the eye by the image formed by an optical instrument to that subtended at the eye by the object when not viewed through the instrument.
Here we have to find the angular magnification when the object is at the focal point.
Focal length = 6.00 cm
Formula to calculate angular magnification:
Angular magnification = 25/f
= 25/ 8.5
= 2.94
Therefore the angular magnification of this thin lens is 2.94
