Answer:
Explanation:
Given that
Wavelength λ=192 nm
So energy of photon,E
Now by putting the values
We know that
Kinetic energy given as
Iron, and lack of red blood cells can cause anemia so you'd need those to prevent it.
All the 4 processes are correct answer to change the state of matter. Hope it helps.
Okay first you have to recognize that the maximum Gravitational potential energy will equal the maximum kinetic energy. The maximum GPE will equal when the stone is at its highest point and the max KE will be right before the stone hits the ground. So
GPE max = KE max
mgh = 1/2mv^2
Mass cancels as it is on both sides
gh = 1/2v^2
Multiply by 2
2gh = v^2
Square root
v = √2gh
Now plug in
v = √2(9.8)(4)
v = 8.85 m/s
Now use the mass to calculate the momentum just before it hits the ground as this is the speed right before it hits the ground
p = mv
p = (3)(8.85)
p = 26.55 kgm/s
