Explanation:
Height of object =5cm
Position of object, u=−25cm
Focal length of the lens, f=10cm
Position of image, v=?
We know that,
v

So,

That is,

So,
v=

=16.66cm
Thus, distance of image is 16.66cm on the opposite side of lens.
Now, magnification =

v
That is,
m=

16.66
=−0.66
Also,
m=

heightofimage
or
−0.66=
5cm
heightofimage
Therefore, Height of image =3.3cm
Answer:
A hockey puck having a mass of 0.30 kg slides on the frictionless, horizontal surface of an ... magnitude of 5.0 N, and the force F2 has a magnitude of 8.0 N. Determine both ... A large man and a small boy stand facing each other on frictionless ice. They ... A hockey puck on a frozen pond is given an initial speed of 20.0 m/s.
Large amounts of water do have a big impact on the weather: indeed, it takes less energy to warm/cool land than water.
Therefore, places near large amounts of water tend to have smaller differences in temperature between summer and winter than places far from waters.
Hence, during winter in Puerto Rico, alongside the coast, the temperature will be higher than in the innermost parts of the island.
Answer:
F = 1.099N
