Why are frying pans usually made out of metal?

Answers

Answer 1
Answer: We need heat to cook food. So, frying pans need to be a good conductor of heat. Since, metals are good (best) conductor of heat, frying pans are made out of metals.
Answer 2
Answer: Frying pans see usually made out of metal because metal is a great conductor of heat. The food can then cook faster. Why is metal a good conductor? it is because the molecules are tightly packed together, allowing the heat to travel through quickly

Plz help.How do ions form electrically neutral compounds?

Answers

They form electrically neutral compounds because the number of captions (positively charged ions) is equal to the number of anions (negativley charged ions) These ions are held together by strong electrostatic forces of attraction.

Where does the name "Black Hole" get it's name?

Answers

The "Black Hole" gets its name from the astronomical amount of gravitational force created by the black hole. This gravitational force is so great that even light cannot escape it, hence, it is completely black

nothing escapes them not even light therefore they are (dark) and  we see them be literally black holes

near the earth surface the amount of mass an object has does not affect its acceleration due to gravity

Answers

Answer:

True

Explanation:

As per the gravitational law, the gravitational force (F) can be expressed as

F = (GMm)/(r^(2) ) -------------  (1)

where,

F= Gravitational force

G= Gravitational constant

M= Mass of the Earth

m= Mass of the object

r= Distance between Earth and object

Also, the force due to gravity,

F=mg -------------  (2)

where,

F= Gravitational force

g= Acceleration due to gravity

m= Mass of the object

Deducing both the equations

mg = (GMm)/(r^(2) )\n g = (GM)/(r^(2) )\n

From the above equation it is clear that the acceleration due to gravity is independent of the mass of the object.

The rate at which work is done is called

Answers

Answer:

The rate at which work is done is called Power.

Explanation:

Power is work done per unit time. or it can also be defined as ratio of work done to time taken to complete the work.

Mathematically the power (P) is given as:

Power(Watts)=(W(Joules))/(T(seconds))

1 watt = 1 Joule/second

Where:

W = Work done in time T.

T = Time taken to complete the work

The rate at which work is done is called Power.
Power is the rate at which work is done, measured in Joules per second
