Explanation

Kinetic energy formula: KE = ½ mv²

Let initial KE = ½ * m * v²  

New KE = ½ * (3m) * (2v)²  

= ½ * 3m * 4v²  

= 6mv²  

Now divide new KE by original KE:  

(6mv²) / (½mv²) = 12 times

Explanation

The work done on a unit charge against an electric field intensity is called electric potential.

It is also known as voltage or potential difference.

It is measured in volts (V) and represents the energy transferred per unit charge.

Electric potential (V) = Work done (W) / Charge (Q)

V = W / Q

Explanation

Counterclockwise is the positive rotation direction

and clockwise is the negative direction.

For example, a torque that rotates an object counterclockwise is a positive torque

Explanation

 joule is a scalar quantity.

SI base units: kg⋅m2⋅s−2

Symbol: J

joule, a unit of work or energy in the International System of Units (SI)

Explanation

Quantum numbers describe values of conserved quantities in the dynamics of a quantum system

Explanation

Escape velocity depends on the mass and radius of a planet.  

   - Mercury has the lowest mass and smallest radius, hence the least escape velocity.  

Explanation

During gastrulation, the upper layer formed is called the epiblast. 

During the early stages of embryonic development, a process called gastrulation transforms a bilaminar disk (consisting of the epiblast and hypoblast) into a trilaminar disk.

The epiblast is the upper layer, while the hypoblast is the lower layer.

The epiblast eventually develops into the ectoderm. 

Explanation

Myxospores are the spores produced by myxobacteria, specifically during a complex multicellular developmental process that occurs under conditions of nutrient starvation.

These spores are formed within a fruiting body, a three-dimensional structure that the myxobacteria aggregate to form when resources are scarce. 

Explanation

 - In a pure capacitive circuit, the current leads the voltage by 90°.

- In a pure inductive circuit, the current lags behind the voltage by 90°.

- In both cases, there is a 90° phase difference between current and voltage

Explanation

The compound with the most acidic proton is Thiol. 

Thiols (R-SH):

These are more acidic than alcohols due to the larger size of sulfur compared to oxygen, resulting in a weaker S-H bond and a more stable conjugate base.
