Answer:
v = 0.012 m/s
Explanation:
This is a problem of momnetun, to solve it we must define a system that includes both players. In this case the forces during the crash are internal forces and the momentum is preserved
Initial
p₀ = m₁ v₁₀ + m₂ v₂₀
Final
= (m₁ + m₂) v
Because the two players are united
p₀ =
m₁ v₁₀ + m₂ v₂₀ = = (m₁ + m₂) v
v = (m₁ v₁₀ + m₂ v₂₀) / (m₁ + m₂)
let's calculate
v = (110 4.20 - 135 3.40) / (110 + 135)
v = 3/245
v = 0.012 m/s
The positive sign indicates that they move to the right
1 mole of photons contain
photons (Avogadro number). This means that 3.0 moles of photons contain
photons.
The wavelength of the light in the problem is
, so the frequency is
The energy carried by a single photon is
where
is the Planck constant, while f is the frequency. Since this is the energy carried by a single photon, the energy carried by 3.0 moles of photons will be the energy of the single photon multiplied by the total number of photons:
which corresponds to E=536 kJ.
Answer:
<em>Is radiation of sufficient energy to produce ions.</em>
<em>Is radiation of sufficient energy to remove electrons from atoms.</em>
Explanation:
Ionization radiation is a radiation that travels at a high speed, and possesses sufficient speed to knock electrons off of an atom or a molecule, ionizing the atom. Ionization radiation can be made of travelling subatomic particles, or an electromagnetic wave with high energy, usually the types found at the end of the electromagnetic spectrum. Some subatomic particles that produce ionization are alpha particle, beta particles, and neutron. The electromagnetic waves with ionization abilities includes Gamma rays. -rays, and high energy ultraviolet rays.
Answer:
I (cylinder) = 1/2 M R^2
I (sphere) = 2/5 M R^2
The equation of motion shows
I * alpha = M g R sin theta = const
An increase in the moment of inertia will result in a smaller acceleration
The cylinder will have the smallest forward velocity because it will arrive at the bottom after the sphere
