Answer:
they're more inclined to be violent so A
Answer:
-589.05 J
Explanation:
Using work-kinetic energy theorem, the work done by friction = kinetic energy change of the base runner
So, W = ΔK
W = 1/2m(v₁² - v₀²) where m = mass of base runner = 72.9 kg, v₀ = initial speed of base runner = 4.02 m/s and v₁ = final speed of base runner = 0 m/s(since he stops as he reaches home base)
So, substituting the values of the variables into the equation, we have
W = 1/2m(v₁² - v₀²)
W = 1/2 × 72.9 kg((0 m/s)² - (4.02 m/s)²)
W = 1/2 × 72.9 kg(0 m²/s² - 16.1604 m²/s²)
W = 1/2 × 72.9 kg(-16.1604 m²/s²)
W = 1/2 × (-1178.09316 kgm²/s²)
W = -589.04658 kgm²/s²
W = -589.047 J
W ≅ -589.05 J
Kinetic energy means fast move movement
Answer:
It [the diamond] would act like a prism, and make a rainbow, or, the light would break up and disappear
Explanation:
that's what I would think at least
Answer:
So wavelength in nm will be
Explanation:
We have given that the energy = 207 KJ/mol ![=207\times 10^3j/mol](https://tex.z-dn.net/?f=%3D207%5Ctimes%2010%5E3j%2Fmol)
Speed of light ![c=3\times 10^8m/sec](https://tex.z-dn.net/?f=c%3D3%5Ctimes%2010%5E8m%2Fsec)
Plank's constant ![h=6.6\times 10^{-34}J-s](https://tex.z-dn.net/?f=h%3D6.6%5Ctimes%2010%5E%7B-34%7DJ-s)
According to plank's rule energy of the photon is given by
![E=\frac{hc}{\lambda }](https://tex.z-dn.net/?f=E%3D%5Cfrac%7Bhc%7D%7B%5Clambda%20%7D)
![207\times 10^3=\frac{6.6\times 10^{-34}\times 3\times 10^8}{\lambda }](https://tex.z-dn.net/?f=207%5Ctimes%2010%5E3%3D%5Cfrac%7B6.6%5Ctimes%2010%5E%7B-34%7D%5Ctimes%203%5Ctimes%2010%5E8%7D%7B%5Clambda%20%7D)
![\lambda =0.956\times 10^{-28}m](https://tex.z-dn.net/?f=%5Clambda%20%3D0.956%5Ctimes%2010%5E%7B-28%7Dm)
So wavelength in nm will be ![\lambda =0.956\times 10^{-19}nm](https://tex.z-dn.net/?f=%5Clambda%20%3D0.956%5Ctimes%2010%5E%7B-19%7Dnm)
