Answer:
It's best to also include the options since this is a multiple choice question! But the best answer would be D.

La conservación de la momentum lineal dicta que la momentum total antes y después de la explosión de la granada debe ser la misma, o sea, cero. Teniendo en cuenta la dirección de cada trozo post-explosión, puedes resolver para hallar la velocidad del segundo trozo.
Este problema se resuelve usando las leyes de conservación de la momentum lineal, que dice que la momentum total de un sistema de partículas permanece constante siempre que no actúen fuerzas externas. En este caso, la granada explota en dos trozos, pero como la granada estaba inicialmente en reposo, la momentum total inicial sería cero. Así que, tras la explosión, la momentum total debe seguir siendo cero.
Puedes escribir la ley de conservación de la momentum para este ejemplo como sigue:
0 = momentum del trozo de 2.5 kg + momentum del trozo de 1.5 kg
Como sabemos, la momentum es el producto de la masa por la velocidad, así que para el trozo de 2.5 kg, la momentum sería 2.5 kg * 120 m/s que va a la derecha (puedes tomarlo como positiva). Luego, mujeres definir la velocidad del trozo de 1.5 kg como 'v', su momentum seria -1.5 kg * v (porque va a la izquierda, lo tomas como negativo).
Por ende,
0 = 2.5 kg * 120 m/s - 1.5 kg * v
De esta ecuación puedes resolver para 'v' y hallarás la velocidad del segundo trozo. Lo negativo indica que va a la izquierda.

Taking $50 from an unattended purse is an example of larceny. The correct Option is B.
Larceny is a type of theft that involves the taking of someone else's property without their consent and with the intent to permanently deprive them of it. It is often referred to as "simple theft" and is considered a crime in most legal systems around the world.
Larceny can take many forms, including stealing money or goods from a store, taking personal property from an individual, or taking valuables from an unattended location. The key element of larceny is that the property is taken without the owner's consent, and the perpetrator intends to keep the property permanently.
The severity of the crime of larceny can vary depending on the value of the property stolen and the circumstances of the theft. In many legal systems, larceny is classified as a misdemeanor or a felony, with the latter carrying a more severe penalty.
In addition to criminal penalties, a person convicted of larceny may also be subject to civil lawsuits and may be required to pay restitution to the victim. Overall, larceny is a serious crime that can have significant consequences for both the perpetrator and the victim.
Here in the question,
Larceny is a type of theft that involves the taking of someone else's property without their consent, with the intent to permanently deprive them of it. It is often referred to as "simple theft."
Option A (taking a man's wallet while threatening him with a firearm) is an example of robbery, which involves the use of force or threat of force to take someone else's property.
Option C (stealing a man's car) is an example of grand theft auto, which is a specific type of larceny that involves the theft of a motor vehicle.
Option D (breaking into a home and stealing $10,000 cash) is an example of burglary, which involves unauthorized entry into a building with the intent to commit a crime, such as theft.
Therefore, the correct option that is an example of larceny is B (taking $50 from an unattended purse) as it involves the taking of someone else's property without their consent, with the intent to permanently deprive them of it.

Answer:
It is based on the principle of electromagnetic induction.
Explanation:
When a magnetic flux linked with a coil changes, an induced emf and induced current is developed in the coil. This phenomenon is called electromagnetic induction.
AC current is time varying sinusoidal current, but DC current is steady current.
When an AC current pass through the primary coil of transformer, the magnetic flux linked with the coil changes. This magnetic flux is linked with the secondary coil which is placed near to the primary coil. As the flux changes in the secondary coil, the induced voltage and current is produced in the secondary coil of transformer.
In case of DC current, there is no changing flux because DC current is steady current, so DC current would not work in case of transformer.
Answer: The correct answer is mechanical energy.
Explanation:
Mechanical energy is the sum of the both potential and kinetic energies.
M.E = P.E + K.E
Potential energy is due to the position of the object.
Kinetic energy is due to the motion of the object.
When the barbell is lifted then it will have potential energy with small amount of kinetic energy.
When the shot put is thrown then there will be both potential energy and the kinetic energy.
Therefore, the mechanical energy is present in a barbell being lifted or a shot-put being thrown.
