Answer: d
Explanation:
Did you actually try to answer the question its obviously d they all have same miles per hour as 100 so there would be nothing different so it would be d.
Answer: QUANTUM MECHANICAL MODEL OF THE ATOM.
Explanation:Edwin Schrodinger is an Australian Physicist,who proposed the Quantum mechanical model of an Atom,this theory helped to give a better understanding of Bohr's model.
According to Bohr's model,it is believed that electrons are concentrated around the circular shell of the Nucleus of an Atom which Edwin Schrodinger improved by proofing that the Behaviors of electrons around an the Nucleus of an Atom can be explained by the Mathematical representation of their waves.
True is the correct answer
Answer:
Explanation:
Object distance = distance between object and lens
u = 50 - 12 = 38 cm
image distance v = 88 - 50 = 38 cm
i )
using lens formula
1 / v - 1 / u = 1 / f
1 / 38 - 1 / - 38 = 1/f
2 / 38 = 1 / f
f = 19 cm
ii ) So object is placed at 2 f or at the center of curvature of the lens .
If object distance is changed to 50 - 31 = 19 cm
using lens formula
1 / v - 1 / u = 1 / f
1 / v + 1 / 19 = 1/19
1 / v = 0
v = infinity
It is so because now the object is placed at the focal distance
iii )
If object further shifts towards the lens , then virtual image of object will be formed behind the lens which will be larger than object .
