Answer:
1. K.E = 11.2239 kJ ≈ 11.224 kJ
2.
3.
Solution:
Now, the kinetic energy of an ideal gas per mole is given by:
K.E =
where
m = no. of moles = 3
R = Rydberg's constant = 8.314 J/mol.K
Temperature, T = 300 K
Therefore,
K.E =
K.E = 11223.9 J = 11.2239 kJ ≈ 11.224 kJ
Now,
The heat capacity at constant volume is:
Now,
Required heat transfer to raise the temperature by is:
Answer:
Some object have less gravitational pull than other objects.
Explanation:
Answer:
15 m/s to the right
Explanation:
Let's say right is positive and left is negative.
Momentum is conserved:
m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂
(6.0 kg) (25.0 m/s) + (15 kg) (0 m/s) = (6.0 kg) (-12.5 m/s) + (15 kg) v₂
v₂ = 15 m/s
The energy of a single photon at the transmitted frequency is
Answer: Option b
<u>Solution:</u>
Energy of photon is given as
Where c is the velocity of Light
h is planck's constant
λ is the wavelength of photon
Energy of photon can be rewritten as
Where f is the frequency of photon
Frequency of photon is obtained by dividing velocity of light by wavelength of photon.
