The kinetic energy of another body having three times the mass of the given object will be 108 J

Kinetic energy-In physics, the kinetic energy of an object is the energy  it has due to  motion. It is defined as the work required to accelerate a body from a given mass from rest to a specified speed.

The kinetic energy of a body is given by \(K.E= \frac{1}{2}Mv^{2}\) (first equation)

Given K.E= 36J

Now the mass of second body is m=3M

also the second body is moving with the same speed v

So kinetic energy of second body K.E₂= \(\frac{1}{2}mv^{2} =\frac{1}{2}(3M)v^{2}\)=36×3

=108J (from first equation)

the specimen will not fail because the stress intensity factor is below the critical value required for crack propagation. This means that the internal crack with a length of 0.30mm and a tip radius of curvature of 5×10-4 mm will not cause failure in the ceramic material.

The main answer to the question is that the specimen will not fail if its most severe flaw is an internal crack with a length of 0.30mm and a tip radius of curvature of 5×10-4 mm.

This is because the stress intensity factor, which determines whether a crack will propagate or not, is calculated using the formula K = Y * (σ * √(π * a)), where K is the stress intensity factor, Y is a geometric factor, σ is the stress applied, and a is the crack length.

In this case, the stress intensity factor is below the critical value needed for crack propagation.

To further explain, the stress intensity factor depends on the crack length, the applied stress, and the geometric factor, which accounts for the shape and orientation of the crack.

In this scenario, the crack length and the applied stress are provided, and assuming a typical value for the geometric factor, the stress intensity factor is calculated to be below the critical value for crack propagation. the specimen will not fail.

Answer: 170 Celsius = 338 Degree Fahrenheit

170 Celsius in Fahrenheit 340°F. Celsius (°C) is a temperature scale based on 0° for the melting point of ice and 100° for the boiling point of water.

What is Celsius?

It was devised by the Swedish astronomer Anders Celsius in 1742. Celsius is now the most widely used temperature scale, with the international standard metric definition being that 0°C is equal to 273.15K (Kelvin). Celsius is an absolute temperature scale, meaning that the zero point is the same everywhere. This makes it easy to compare temperatures in different locations. The degree Celsius is an important unit of temperature in many fields and is used to measure air temperature, ocean temperature, and many other temperatures.  170 Celsius in Fahrenheit 340°F.Fahrenheit = (Celsius × 9/5) + 32Fahrenheit = (170 × 9/5) + 32Fahrenheit = (1540/5) + 32Fahrenheit = 308 + 32Fahrenheit = 340°F

When you add air to a balloon, the pressure inside the balloon increases, causing it to expand.

This is because the air pressure outside the balloon is greater than the air pressure inside the balloon. On the other hand, when you add air to a steel tank, the pressure inside increases as well, but the steel tank is able to withstand much higher pressure than a balloon, so the pressure inside the steel tank will not increase as quickly.

Answer:

The car will take approximately 4.865 seconds to splash into the water.

Explanation:

Let suppose that car moves initially downwards. We must see the kinematics of the car after being thrown off the bridge, it is quite certain that car experiment a free fall, in which it is accelerated uniformly by gravity. The time spent by the car to splash into the water is obtained from this equation of motion:

\(y = y_{o}+v_{o}\cdot t +\frac{1}{2}\cdot g \cdot t^{2}\)

Where:

\(y\) - Current height, measured in feet.

\(y_{o}\) - Initial height, measured in feet.

\(v_{o}\) - Initial velocity, measured in feet per second.

\(t\) - Time, measured in seconds.

\(g\) - Gravitational acceleration, measured in feet per square second.

If we know that \(y = 0\,ft\), \(y_{o} = 624\,ft\), \(v_{o} = -50\,\frac{ft}{s}\) and \(g = -32.174\,\frac{ft}{s^{2}}\), this quadratic function is obtained:

\(-16.087\cdot t^{2}-50\cdot t +624 = 0\)

Now we get the roots of the polynomial by Quadratic Formula:

\(t_{1} \approx 4.865\,s\), \(t_{2} \approx -7.973\,s\)

Only the first root is physically reasonable. In a nutshell, the car will take approximately 4.865 seconds to splash into the water.

Answer:

Force = 304.5 Newton

Explanation:

Given the following data;

Initial velocity, u = 0m/s (since it started from rest).

Final velocity, v = 42m/s

Time, t = 0.02 secs

Mass = 0.145 kg

To find the force;

First of all, we would have to determine the acceleration of the ball;

Acceleration = (v - u)/t

Acceleration = (42 - 0)/0.02

Acceleration = 42/0.02

Acceleration = 2100 m/s²

Now, we solve for the force;

Force = mass * acceleration

Force = 0.145 * 2100

Force = 304.5 Newton

In a a camera equipped with a 55-mm-focal-length lens, what is the object distance if the image height equals the object height.The object is effectively located at an infinite distance from the camera lens.

To determine the object distance in this scenario, where the image height equals the object height, we can use the lens formula:

1/f = 1/d_o + 1/d_i

Where:

f is the focal length of the lens,

d_o is the object distance,

and d_i is the image distance.

Given that the focal length (f) is 55 mm, and the image height (h_i) equals the object height (h_o), we can assume that the image distance (d_i) is equal to the focal length (f) due to the nature of the scenario.

Substituting the known values into the lens formula, we have:

1/55 = 1/d_o + 1/55

Simplifying the equation, we get:

1/d_o = 1/55 - 1/55

1/d_o = 0

Since the equation results in 0, it implies that the object distance (d_o) is at infinity in this scenario. The object is effectively located at an infinite distance from the camera lens.

As for the distance between the object and the image on the film, it is not possible to determine it precisely without additional information, such as the specific type of camera and the positioning of the film plane relative to the lens. However, in typical camera setups, the image on the film is formed when the object is located at the focal point of the lens or at a significant distance from the lens, resulting in a sharp image on the film plane.

The density of a substance that has a mass of \(20 g\) and a volume of \(10 mL\) is \(2 g/cm^{3}\).

Density of substance is defined as its mass per unit volume. Density gives information about how tightly the substance is packed together. The formula for density is

\(d =\frac{m}{V}\)

Where,

\(d =\) density

\(m =\) mass

\(V =\) volume

Unit of density is grams per cubic centimetre.

One of the most common uses of density is in how different materials interact when mixed together.

Specific Gravity is the ratio of the substance's density to the density of water. An object having specific gravity less than one will float in water, while a specific gravity greater than one will sink.

Given
