The gauge pressure of the air in the tires when its temperature rises to 27.0 degrees celsius and its volume increases to 1.67 x 10-2 m3 is 175 kPa.
What is temperature?Temperature is a measure of the average kinetic energy of the particles in a system. It is measured using a thermometer and is typically expressed in units of degrees Celsius (°C), Fahrenheit (°F), or Kelvin (K). Temperature is an important factor in determining the state of matter, as well as the rate of chemical reactions and the motion of particles within a system.
The ideal gas law states that PV = nRT, where P is the pressure, V is the volume, n is the number of moles of gas, R is the ideal gas constant, and T is the temperature. Therefore, we can rearrange the equation to solve for P:
P = (nRT) / V
We can plug in the given values to find the initial pressure:
P = [(1.67 x 10-2 m3)(1.01 x 105 pa) / (1.64 x 10-2 m3)] / (0.00 + 273.15)
P = 165 kPa
Now, we can find the new pressure when the temperature rises to 27.0 degrees celsius and the volume increases to 1.67 x 10-2 m3:
P = [(1.67 x 10-2 m3)(1.01 x 105 pa) / (1.67 x 10-2 m3)] / (27.0 + 273.15)
P = 175 kPa
Therefore, the gauge pressure of the air in the tires when its temperature rises to 27.0 degrees celsius and its volume increases to 1.67 x 10-2 m3 is 175 kPa.

it would take approximately years to receive light from a civilization on the opposite side of the galaxy. a. 100000 years. b. 10 yrs. c. 100 yrs. d. 1/4 of a year.
It would take approximately 100,000 years to receive light from a civilization on the opposite side of the galaxy. The correct answer is, therefore (a) "100,000 years".
This is because the distance between the Earth and the opposite side of the galaxy is approximately 100,000 light-years. Light travels at a speed of approximately 300,000,000 meters per second, so it would take approximately 100,000 years for light to travel from the opposite side of the galaxy to the Earth.
A light-year is a unit of distance that is equal to the distance that light travels in one year. Light travels at a very high speed, approximately 300,000,000 meters per second, so it is able to cover a large distance in a relatively short amount of time.

a 40cm diameter wheel accelerates uniformly from 240 rpm to 360 rpm in 6.5 seconds. how far will a point on the edge of the wheel have traveled in this time
Answer:
S = V1 t + 1/2 a t^2 distance traveled for linear acceleration
θ = ω1 t + 1/2 α t^2 equivalent angle for rotational acceleration
ω1 = 240 / min * 2 π * 240 / (60 s/min) = 8 π / s
ω2 = 360 rpm = 12 π / s
α = 4 π/ 6.5 s^2 = .62 π / s^2 angular acceleration
θ = 8 π / s 6.5 s + .62 π / 2 * 6.5^2
θ = 52 π + 13 π = 65 π = 65 * π / (2 π / rev) = 32.5 rev
1 rev = 2 * π * R = 2 * π * .4 m = 2.51 m / rev

Answer:
13) A student walks 20 m north, 10 m south, and 3 m north. To have a displacement of 0 m, the student should walk 13m toward the south.
Answer:
13 m towards the south
Explanation:
First, the student walks 20m North.
Then the student walks 10m South. This means that the student is now (20 - 10 m) north = 10m North
Now the student walks 3m North
Therefore the student is now ( 10 + 3m) north
= 13m North.
To return to starting position, the person should walk 13m south.

What is your average speed (a) from New Delhi to Agra, (b) from Agra to New Delhi, (c) for the entire trip? (d) What is your average velocity for the entire trip?
Answer:
below
Explanation:
d = distance from ND to A
Average speed = total d / total time
a) total distance = d
= 1/2 t * 55 + 1/2 t * 90 total time = t
average speed = d / t = (1/2 t *55 + 1/2 t*90) / t
= 1/2 *55 + 1/2 * 90 = 72.5 km/hr av
b) time at 55 = 1/2d /55 time at 90 = 1/2 d 90

What is Conservation of momentum?Conservation of momentum is a law of physics which states that the total momentum of a system remains constant over time. This means that when two or more objects interact, the total momentum of the system remains the same before and after the interaction. The law of conservation of momentum is applicable to both isolated systems and systems that interact with external forces. It is an important concept in a variety of applications ranging from collisions of particles to the motion of galaxies. Conservation of momentum also plays an important role in the field of quantum mechanics.
The initial speed of the bullet can be calculated using the conservation of momentum equation:
m₁v₁ + m₂v₂ = m₁v′₁ + m₂v′₂
where m₁ is the mass of the bullet, v₁ is the initial speed of the bullet, m₂ is the mass of the pendulum, v₂ is the initial speed of the pendulum, v′₁ is the final speed of the bullet, and v′₂ is the final speed of the pendulum.
In this problem, m₁ = 7.0 g, v₁ = ?, m₂ = 1.5 kg, v₂ = 0 m/s, v′₁ = 200 m/s, and v′₁ = 0 m/s.
Substituting this into the equation, we get:
7.0 g x v₁ + (1.5 kg)(0 m/s) = 7.0 g(200 m/s) + (1.5 kg)(0 m/s)
Solving for v₁, we get:
v₁ = 200 m/s

When the distance between two masses doubles, the strength of the gravitational force between them is decreased by a factor of 4.
Gravitational Force:
Any two mass-containing objects are attracted to one another by gravitational force. Because it consistently attempts to pull masses together rather than pushing them apart, the gravitational force is known as attractive. In reality, everything in the cosmos is tugging on everything else, including you! Newton's Universal Law of Gravitation is what it is known. Admittedly, you aren't pushing on those other objects all that much because you don't have a very large mass. Additionally, items that are very far apart from one another do not clearly tug on one another. However, we can calculate the force because it exists.
It is given by,
