Electrical energy is used to turn the blades of a fan. The amount of energy transformed is seen here: 750 J electrical energy is

Alchen [17]

B) It was transformed into 350 J of heat energy.

Explanation:

The remaining 350J of energy must have been transformed into 350J of heat energy.

A fan works by converting electrical energy into heat energy.

According to the third law of thermodynamics "no system is 100% efficient". The conversion of the energy from one form to another involves a lost in energy.
Heat is one very familiar way by which energy can be lost.
Some component energy is used to heat the fan in the process and it is a wasted energy.
Friction surfaces a heat energy in this process.

COMPARE: Identify three ways that a biologist’s research is similar to an astronomer’s.

dalvyx [7]

Biologist and astronomer both use tools that magnify so they are able to view minute objects. Astronomers use telescopes while biologists use microscopes.
They both require data science due to the enormous data they are collecting that needs to be analyzed. Astronomers are collecting data on millions of stars and galaxies. Biologists require data science to analyze the enormous genomic data from populations.
Both fields involve making new discoveries due to the enormity of the scale in their scopes. Biologists and astronomy attempt to find new planets and those that could harbor extra-terrestrial life while biology attempts to find new undiscovered species of organisms on earth.
