A 10kg mass is lifted to a height of 2m. What is it’s potential energy at this position

196J

Explanation:

From the question given, the following were obtained:

m = 10kg

h = 2m

g = 9.8m/s2

P.E = mgh

P.E = 10 x 9.8 x 2

P.E = 196J

the answer is d : ) have a good da

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance
