A car tire is fully inflated to a pressure of 32 psi at 25 °C. After driving for 2 hours, the volume of the tire is unchanged, but pressure of the tire is now 36 psi. What is the new temperature of the gas inside the tire?What caused this change?
Answers
Answer:
50.5°C
Explanation:
Start with the ideal gas law:
PV = nRT
Rearranging:
P/T = nR/V
Since the right side is constant (volume and mass don't change):
P₁ / T₁ = P₂ / T₂
This equation is also known as Gay-Lussac's law. Plugging in the values (make sure to use absolute pressure and temperature):
(32 psi + 14.7 psi) / (25 + 273.15) K = (36 psi + 14.7 psi) / T
Solving for T:
T = 323.69 K
T = 50.5°C

The only thing we can calculate is the total energy in the pendulum.
When the pendulum is at the bottom of its swing, ALL of its energy
is kinetic.
Kinetic energy = (1/2) x (mass) x (speed)²
= (1/2) x (2 kg) x (4.1 m/s)²
= 4.1 kg-m²/sec²
= 4.1 Joules .
In principle, we can also calculate how HIGH the 'bob' is at the end of
its swing, because now we know how much total energy the pendulum
has, and at the ends of the swing, the energy is all potential.
Potential energy = (mass) x (gravity) x (height)
4.1 J = (2 kg) x (9.8 m/s²) x (height)
Height = (4.1 kg-m²/s²) / (19.6 kg-m/s²)
= 0.209 meter high
and that's as far as we can go. None of this points us toward
calculating the length of the pendulum.

Wave A will be faster than the wave B because
What is the frequency of the wave?
The frequency of the wave is defined as the cycle completed by the wave per second.
Now it is given in the question:
Frequency of wave A = 250 hertz
The wavelength of wave A= 30 cm
Frequency of wave B = 260 hertz
The wavelength of wave B= 25 cm
Now for finding which wave is faster we will calculate the velocity of the wave.
For Wave A
For wave B
We can see that the velocity of wave A is higher than the velocity of wave B.
Thus wave A will be faster than the wave B because
To know more about the frequency of waves follow
Wave A
250×30×10^-2=75 m/s
Wave B
260×25×10^-2=65 m/s
Therefore
Wave A is faster

The model of the atom that has electrons traveling in specific paths around the nucleus is Rutherford's model.
Therefore, the correct answer is option B
J. J Thomson proposed that the atom is a sphere of positively charged matter in which negatively charged electron are embedded.
In Rutherford's model of atomic structure, the electrons moves in orbits by electrostatic attraction to the positively charged nucleus.
According to Dalton's atomic theory, atom were indestructible and indivisible solid particle.
Bohr's model made assumption that electron can only exist in circular orbits of definite quantum energy.
According to the question, the model of the atom that has electrons traveling in specific paths around the nucleus is Rutherford's model.
Therefore, the correct answer is option B
