A portion that has been severed or separated from another object is known as a fragment. The term "fragment" typically refers to a part that has broken off rather than one that has been softly or purposefully detached, as in The vase was smashed into a million fragments. A bone fragment is a piece of a bone that has been chipped off, often in a minor amount. Another definition of the word "fragment" is "a section or portion of something that is incomplete or separated from the total," such as a scene from a film or a musical composition. The word "fragment" can also refer to a portion, little, or scrap (regardless of whether it has been removed from a larger part).

The energy of a photon of Red light is found to be [tex]2.92 \times 10^{-19}J.[/tex]

Photons have momentum, which is determined by the equation p=h, where h is the planck's constant. The momentum and energy of photons are correlated by the formula p=Ec, where E=hf=hc.

A photon is a microscopic particle of electromagnetic energy that resembles a light particle. The photon's energy is influenced by its frequency. Photons are essentially electric fields traveling through space. Photons have no charge and no rest mass, and they move at the speed of light. Because a photon has no mass, its kinetic energy is the same as its total energy.

X-ray are electromagnetic waves, which are a type of radiation. Images of the inside of your body are produced by X-ray imaging. The images depict various parts of your body in black and white. This is due to the fact that different tissues absorb varying amounts of radiation. Because calcium in bones absorbs the most x-rays, they appear white. Fat and other soft tissues absorb less and appear grayer as a result. Because air absorbs the least amount, the lungs appear black.

Answer:

To find the direction and speed of the two cars after the collision, you need to perform a momentum analysis. The momentum of the two cars before the collision can be calculated as follows:

Momentum of car c = 1325 kg * 27.0 m/s = 35725 kg m/s (north)

Momentum of car d = 2165 kg * 11.0 m/s = 23815 kg m/s (east)

The total momentum of the two cars after the collision is equal to the sum of their momenta before the collision. This is a vector sum, which can be represented by an arrow pointing in the direction of the total momentum.

The final velocity of the two cars can be found by dividing the total momentum by the total mass.

Total momentum = 35725 kg m/s + 23815 kg m/s = 59540 kg m/s

Total mass = 1325 kg + 2165 kg = 3490 kg

Final velocity = Total momentum / Total mass = 59540 kg m/s / 3490 kg = 17.0 m/s

This velocity is directed somewhere between north and east. The exact direction and speed of the two cars after the collision depends on their initial positions and orientation, which are not specified in the question.

Answer:

each spring will extend 0.049 m / 2 = 0.024 m.

Explanation:

The total spring constant of the two springs in series is 150 N/m (50 N/m + 100 N/m). The extension of the two springs can be calculated using Hooke's law:

F = kx

where F is the force applied to the spring (in this case, the weight of the 0.50 kg mass), k is the spring constant, and x is the extension of the spring.

So, x = F / k = (0.50 kg * 9.8 m/s^2) / 150 N/m = 0.049 m

This is the total extension of the two springs combined. To find the extension of each spring, we need to divide the total extension by the number of springs. Since there are two springs in series, each spring will extend 0.049 m / 2 = 0.024 m.

The required statement about law of conservation of momentum is true.

According to the law of conservation of momentum, The overall momentum of two or more bodies acting on one another in an isolated system stays constant unless an external force is introduced. As a result, momentum cannot be gained or lost.

True. The law of conservation of momentum states that the total momentum of an isolated system remains constant, unless acted upon by an external force. This means that the total momentum of a system, consisting of multiple objects in motion, will remain the same unless a net force is applied to the system.

The law is a fundamental principle of classical mechanics and is widely used to explain the behavior of physical systems, including collisions and other interactions between objects.

The law of conservation of momentum is an expression of the fact that momentum is a conserved quantity in an isolated system, meaning that it cannot be created or destroyed, only transferred from one object to another.

The distance the child covered before catching up to his friend was 0.7 metres.

To find the distance the boy travels before he catches his friend,

we need to calculate the position of the boy as a function of time.

The velocity of the boy can be calculated as the sum of his initial velocity (0 m/s) and his acceleration multiplied by time:

v = at = (2.08 m/s^2) * (1.11 s)

= 2.3 m/s

The position of the boy as a function of time can then be calculated using the following equation:

x = x0 + v0t + (1/2)at^2

Where x0 is the initial position of the boy (assumed to be 0),

v0 is the initial velocity of the boy (0 m/s), and

t is the time elapsed (1.11 s).

Plugging in the values, we get:
