Answer:
The energy used to reach the surface is 1.53 eV.
Explanation:
Given that, the work function of a certain metal is 6.6 eV.
Frequency of photon,
Kinetic energy of the electron,
The energy of the photon is:
Energy utilized by the photon is given by :
Used energy is given by the difference of energy given and the energy utilized. So,
So, energy used to reach the surface is 1.53 eV.
Answer:
The main connective tissue is blood which is found in <em><u>blood vessels</u></em> and capillaries.
It must be radio waves. That's the only electromagnetic wave
the cell towers are equipped to receive and process.
Your phone can pour out all the modulated heat, light or
X-rays it wants to, but the call will never connect, because
there is no cellular network operating at those wavelengths.
Given:
u = 0, initial velocity
v = 125 m/s, final velocity
s = 0.0800 m, distance traveled
9.20 g, the mass of the pellet
If the acceleration is a, then
0² + 2*(a m/s²)*(0.800 m) = (125 m/s)²
1.6a = 15625
a = 9765.625 m/s²
Calculate the force.
F = (9.20 x 10⁻³ kg)*(9765.625 m/s²) = 98.84 N
Answer: 98.8 N (nearest tenth)
