Answer from: vkyles84

The correct answer is Option 2.

Explanation:

From the given options:

Option 1: This happens whenever there is a formation of covalent bond. This is a type of chemical reaction.

Option 2: This reaction is a type of nuclear reaction because here rearrangement of nucleus is taking place.

Option 3: This reaction is a type of reduction reaction because in reduction reaction one atom gains electrons from another atom.

Energy released during nuclear reactions is more than chemical reactions because huge amounts of energy is released at one time. The nuclei in a nuclear reaction undergoes a chain reaction which causes neutrons to move at a very fast rate and thus, it releases high amounts of energy.

Hence, the correct answer is Option 2.

Answer from: nayelimoormann

The correct option is 2 - The nucleus of an atom is divided.

Explanation:

Hello!

Let's solve this!

The process by which the nucleus of an atom is divided is called nuclear fission.

Nuclear fission occurs when a heavy nucleus divides. It releases a lot of energy.

Option one is the description of a covalent union.

Option three describes an ionic union.

The correct option is 2 - The nucleus of an atom is divided.

Answer from: Quest

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.

The scalar triple product computes the magnitude m of the moment of a force vector f about a specified line. it is m = (r × f) · n, where r is the position vector from the line to the point of application of the force and n is a unit vector in the direction of the line. use matlab to compute the magnitude m for the case where f = [12, −5, 4] n, r = [−3, 5, 2] m, and n = [6, 5, −7].
