Explanation:
The radius of curvature of the mirror R = 20 cm
then the focal length f = R/2 = 10 cm
(a) From mirror formula
1/f = 1/di + /1do
then the image distance
di = fd_o / d_o - f
= (10)(40) / 40-10
= 30.76 cm
since the image distance is positive so the image is real
ii) when the object distance d_0=20 cm
di = 10×20/ 20-10
= 20
Hence, the image must be real
iii)when the object distance d_0 = 10
di = 10×10 / 10-10 = ∞ (infinite)
the image will be formed at ∞
here also image will be real but diminished.
Answer:
Here is the answer.
Explanation:
Balanced forces- they are those forces that produce 0 resultant forces.
therefore, on applying a balanced force on the object, it wouldn't result in any change, as resultant force would be 0.
heat excites molecules at their "lattice" sites. Enough to break the lattice bonds set the molecules free of each other and ... melt.
Fission and fusion are two processes that release very little amounts of energy.
