Its an inelastic collision because the force from the bat causes it to bounce back. It is also an elastic force because catching the ball call for the energy of the ball to be deformed and restored into the mitt.
Answer:
The least count of vernier calipers is 0.01 g.
(B) is correct option.
Explanation:
Given that,
The digit that would have to be estimated in reading this instrument,
According to figure,
We need to calculate the pitch
Using formula of pitch
Put the value into the formula
We need to calculate the least count of vernier calipers
Using formula of least count
Put the value into the formula
Hence, The least count of vernier calipers is 0.01 g.
(B) is correct option.
I can’t answer you but here have a meme
Answer: Near the Protons. The electron structure of bromine is illustrated above. In chemical reactions, how does the valence configuration of Bromine tend to change? ... It loses one electron.
Explanation:
btw i found that on google lol
Answer:
Kinetic energy of electron = -E₂ = 3.4 ev
Kinetic energy of electron = -E₄ = 0.85 ev
Explanation:
In case of hydrogen atom energy associated with nth state is,
En = -13.6/n²
For n = 2
E₂ = -13.6 / 2²
E₂ = -13.6/4
E₂ = -3.4 ev
Kinetic energy of electron = -E₂ = 3.4 ev
For n = 4
E₄ = -13.6 / 4²
E₄ = -13.6/16
E₄ = -0.85 ev
Kinetic energy of electron = -E₄ = 0.85 ev
