Answer:
-2 m/s
Explanation:
The computation of the acceleration of the block is as follows:
The volume of the block is
V = 1kg ÷ 1,000 kg/m^3 = 1 ÷ 1,000 m^3
Now at the time of submerging in the oil
Net force is
= -2 m/s
Answer:
To identify the electron transition that has the highest frequency in the hydrogen atom.Answer: The frequency of light produced by electron transition is highest among the given electron transition, therefore, the option (a) is correct.Explanation:The energy of emitted light by the electron transition is given as: is the energy of the initial level. is the energy of the final level.The energy difference for the electron transition is highest among given electronic transition.The energy of the light is given as:Here, is the plank’s constant. is the frequency of the light.The energy of the light is directly proportional to the frequency of the light.Therefore the frequency of light by the electron transition is highest among given electronic transition.
