Answer:
D
Explanation:
Just had the same question and couldnt find and answer so i guessed. heres the answer no lol!
Answer:
C
Explanation:
C would make the most sense because the problem with fossil fuels is the fact that it emits greenhouse gases that warm up the earth over a long period of time as the climate has changed because of it.
This problem here is an example of inelastic collision where kinetic energy is not conserved but momentum is. We calculate as follows:
m1v1 + m2v2 = (m1 + m2)v3
v3 = m1v1 + m2v2 / m1 + m2
v3 = (30.2)(1000) + (5000)(0) / (30.2 + 5000)
v3 = 6.00 m/s
Answer:
Velocity of electron will be equal to 
Explanation:
We have given kinetic energy of electron 
Mass of electron 
We have to find velocity of electron
Kinetic energy of electron is equal to
, here m is mass and v is velocity
So 

So velocity of electron will be equal to 
The closest answer i would go with is b, I'm not completely sure because I'm not sure what the question actually means because there could be any meaning
