the guage pressure in a car tire is 30.0 psi when the air temperature is 0 C as the day warms up and brighten sun shines What is
Viktor [21]

Answer:

P_2 = 33.297\ psi

Explanation:

give,

Gauge pressure of car, P₁ = 30 psi

temperature,T₁ = 0° C = 0 + 273 = 273 K

Assuming temperature at the noon = 30° C

       T₂ = 30 + 273 = 303 K

 Pressure at this temperature, P₂ = ?

Using ideal gas equation

\dfrac{P_1V_1}{T_1}=\dfrac{P_2V_2}{T_2}

taking volume as in compressible  V₁ = V₂

\dfrac{P_1}{T_1}=\dfrac{P_2}{T_2}

\dfrac{30}{273}=\dfrac{P_2}{303}

P_2 = 303\times \dfrac{30}{273}

P_2 = 33.297\ psi

Hence, Pressure of the at 30°C is equal to 33.297 psi.

You and your friends are going on a picnic in a very small car. On your way, the car breaks down and you try to push it to get i
zaharov [31]

Answer:

The pushing of the car by you and your friends is the applied force and when the car moves, it means that the velocity has changed thus causing the movement or acceleration.

Explanation:

Newton's work on forces regarding motion can never be neglected by scientists. Sir Isaac Newton when he was alive, among several of his works he proposed the three laws guiding the forces of motion. In this question we are only going to be treating only one out of the three Newton's Law of motion and that is the second Law Of Newton's laws of motion.

The second Law Of Newton's laws of motion states that the acceleration of an object is directly proportional to the applied force and inversely proportional to the object's mass.

(1). Now, to the question: " How are you and your friends applying Newton's second law of motion here? "

The pushing of the car by you and your friends is the applied force and when the car moves, it means that the velocity has changed thus causing the movement or acceleration.

According to the law, the more the Force, the more the acceleration.

(2). For the second part of the question, " What if the car you were traveling in was a large SUV?"

From the law stated above we see that the acceleration is inversely proportional to the mass, thus if the car is a large SUV, It means that more force is needed to change the car's velocity.
