Matter becomes energy. Law of thermodynamics states that matter can't be created or destroyed, but can transfer to another form. If it was closed in with the form of energy, it would be transferred to the form of energy.

Answer:

The total amount of both matter and energy remains the same

Explanation:

The matter is defined as anything that has some weight and it occupies some volume.

On the other hand, energy is defined as the capacity/ability to do work.

According to the law of conservation, it says that energy can neither be created nor destroyed, but it transforms from one kind to another.

Also according to Einstein's mass-energy equation, it says that matter that is comprised of certain energy is equal to the product of their mass and square of its light speed.

Thus, in a closed system, both matter and energy can change its forms but their total amount remains the same.

dangina [55]

Answer:

The value of a is 150 and b is 4822.

Explanation:

First, you have to expand to remove brackets :

$(5372 + 100 {y}^{2} ) + 5(10 {y}^{2} - 110)$

$= 5372 + 100 {y}^{2} + 50 {y}^{2} - 550$

Next, you have to simplify :

$100 {y}^{2} + 50 {y}^{2} + 5372 - 550$

$= 150 {y}^{2} + 4822$

Next, you have to compare it :

$a {y}^{2} + b = 150 {y}^{2} + 4822$

$a = 150$

$b = 4822$

Given a chance to acquire one of rizal's capabilities, how would you apply it as a student.

lyudmila [28]

Given the capabilities that Jose Rizal had, as a student I would use such powers to fight for students rights and equality on campus.

Jose Rizal was one man that helped his nation to start a revolution against the Spanish. He did this in order for his country to have freedom and control from Spain.

One of his notable works was his letter to the Filipino youths were he stated that any one can begin to serve his country from any age that they wanted.

He is regarded as a national hero in the country because he fought for independence in the country without the use of violent force and aggression.
