Answer: When an object falls, its gravitational potential energy is changed to kinetic energy. You can use this relationship to calculate the speed of the object's descent.

Answer:

To solve this problem, we need to use the formula:

distance = initial velocity x time + 1/2 x acceleration x time^2

where:

initial velocity = 72 km/hour (we need to convert this to m/s to use it in the formula)

time = 5 seconds

acceleration = 10 m/s^2 (assuming this is the acceleration due to gravity)

Converting the initial velocity from km/hour to m/s:

72 km/hour = (72 x 1000 m) / (60 x 60 s) = 20 m/s

Now we can plug in the values into the formula:

distance = 20 m/s x 5 s + 1/2 x 10 m/s^2 x (5 s)^2

distance = 100 m + 1/2 x 10 m/s^2 x 25 s^2

distance = 100 m + 125 m

distance = 225 meters

Therefore, the distance traveled by the bus in 5 seconds is 225 meters.

Explanation:

If you were standing directly at the North Pole, you would see the orbit of the Earth as a flat plane. The closest point known as perihelion and the farthest point known as aphelion.

This is because the Earth's axis is tilted at an angle of 23.5 degrees relative to the plane of its orbit, so from the North Pole, you would be looking directly down onto the orbital plane. However, it's important to note that the orbit of the Earth is not a perfect circle, but rather an ellipse. This means that the distance between the Earth and the Sun varies throughout the year.

The closest point known as perihelion and the farthest point known as aphelion. Despite this elliptical shape, from the North Pole, the orbit would appear as a flat and circular plane, with the Sun appearing to move in a constant arc around the Earth throughout the day. Overall, viewing the Earth's orbit directly from the North Pole would give you a unique perspective on our planet's path through space.

The southern hemisphere's perihelion is when it experiences a summertime increase in light. The condition known as aphelion occurs when the Northern Hemisphere retains heat during the winter months. The spacecraft will create a new aphelion that will remain unaltered in the orbit as it is orbiting the sun.

The density of the substance is 0.913 grams per milliliter (g/mL).

Density is a measure of how much mass is contained in a certain volume of a substance. It is defined as the mass of a substance divided by its volume. In this problem, we need to calculate the density of a substance given its volume and the mass of the substance and the container it is placed in.

To calculate the density of the substance, we need to first determine the mass of the substance alone. We can do this by subtracting the mass of the empty graduated cylinder from the mass of the cylinder with the substance in it.

The mass of the substance can be calculated as follows:

Mass of substance = Mass of cylinder with substance - Mass of empty cylinder

Mass of substance = 15.57 g - 12.55 g

Mass of substance = 3.02 g

Now that we know the mass of the substance, we can calculate its density using the formula:

Density = Mass / Volume

We were given the volume of the substance as 3.31 mL, so we can plug this into the formula:

Density = 3.02 g / 3.31 mL

Simplifying this expression gives us the density of the substance:

Density = 0.913 g/mL

Therefore, the density of the substance is 0.913 grams per milliliter (g/mL). This means that for every milliliter of the substance, there is 0.913 grams of mass. Density is a fundamental property of a substance that can help us identify or classify it.

A graph of KE (kinetic energy) vs the mass of an object is a line, as we know that the kinetic energy depends linearly on the mass of the object.

For an object of mass M moving with velocity v, we define its kinetic energy as:

KE = (M/2)*v^2

We can rewrite it as:

KE = (v^2/2)*M

So, it is a "coefficient" (if we assume that the velocity is constant) times the mass. That gives a linear relationship.

Then we conclude that the kinetic energy depends linearly on the mass, which means that the graph of KE vs the mass of an object is a line.

FOR STEEL BARS:

Since,

where,

(σallow)st = maximum allowable stress of steel bar = 200 MPa = 2 x 10⁸ Pa

A = Cross-sectional area of steel bar = 450 mm² = 0.45 x 10⁻³ m²

(Pmax)st = Maximum allowable force for steel bar = ?

Therefore,

2 x 10⁸ Pa = (Pmax)st/0.45 x 10⁻³ m²

(Pmax)st = (2 x 10⁸ Pa)(0.45 x 10⁻³ m²)

(Pmax)st = 9 x 10⁴ N = 90 KN

FOR Aluminum BARS:

Since,

(σallow)al = (Pmax)al/A

where,

(σallow)al = maximum allowable stress of Al bar = 150 MPa = 1.5 x 10⁸ Pa

A = Cross-sectional area of Aluminum bar = 450 mm² = 0.45 x 10⁻³ m²

(Pmax)al = Maximum allowable force for Aluminum bar = ?

Therefore,

1.5 x 10⁸ Pa = (Pmax)al/0.45 x 10⁻³ m²

(Pmax)al = (1.5 x 10⁸ Pa)(0.45 x 10⁻³ m²)

(Pmax)al = 6.75 x 10⁴ N = 67.5 KN

Since,

(Pmax)al < (Pmax)st

Therefore,

The maximum allowable force will be:

In a piston-cylinder assembly, the gas undergoes a process where the relationship between pressure and volume is given by \(pV^2\) = constant. Given the initial pressure (p1 = 1 bar), initial volume (V1 = \(0.1 m^3\)), and final pressure (p2 = 9 bar), the task is to determine the final volume (V2) in \(m^3\)and the work for the process in kJ.

To find the final volume (V2), we can use the relationship between pressure and volume in the given process. According to \(pV^2\), we can write: \(p1V1^2 = p2V2^2\)\(.\)

Substituting the given values, we have:

\((1 bar)(0.1 m^3)^2 = (9 bar)V2^2.\)

Simplifying the equation, we find:

\(0.01 bar·m^6 = 9 bar·V2^2.\)

Dividing both sides by 9 bar, we get:

\(V2^2 = 0.0011 m^6.\)

Taking the square root of both sides, we obtain: V2 ≈ \(0.033 m^3\).

Therefore, the final volume is approximately \(0.033 m^3\).

To calculate the work for the process, we can use the equation:

Work = ∫(p dV), where p is the pressure and dV represents an infinitesimal change in volume. By integrating this expression over the initial and final volumes, we can determine the work done during the process.
