Answer:
The height of the image is, h' = 6.0 cm
The image is erect.
Explanation:
Given data,
The object distance, u = -5 cm
The focal length of convex lens, f = 10 cm
The object height, h = 3 cm
The lens formula,



v = -10 cm
The magnification factor of lens

m = 2



h' = 6 cm
The height of the image is, h' = 6 cm
The image is erect.
Answer:
The Gravitational force would decrease
Explanation:
To calculate FG the formula is:
Fg=mg
if mass decreases then the gravitational force would decrease
Answer:

Explanation:
In an ideal transformer, the ratio of the voltages is proportional to the ratio of the number of turns of the windings. In this way:

In this case:

Therefore, using the previous equation and the data provided, let's solve for
:

Hence, the number of loops in the secondary is approximately 41667.
