To measure gravitational mass one of the methods includes using a spring balance. a balance is a type of scale that is different because it uses known mass to measure the unknown mass. so technically the method measures the weight.
also if you just want to know normal mass then just weigh the object on the scales because technically speaking when you want to see your weight you are actually seeing your mass. because mass never changes whilst weight is from the result of gravity and always changes, so yeah. I hope thos actually makes some sort of sense
Answer: Option (D) is the correct answer.
Explanation:
An electric circuit works well when all the connections are complete but if any of the connections in the circuit is loose or disconnected then it is possible that current will not flow from the circuit.
Therefore, when Jenna removed one of the clips on the battery then circuit becomes incomplete and as a result there will no flow of current.
Thus, we can conclude that the electrical energy would stop because the circuit is incomplete.
Answer:
Explanation:
so u can work out the amount of moles in FeO3 by doing mr of fe3o3 is 55.8*3+16*3=215.4
moles= mass/mr so you do 15.5g/215.4=0.0719 moles
then using 1 to 1 ratio so O2 moles is 0.0719
then use the equation mass=mole*mr
so 0.0719*16=1.15g
hope this make sense :)
Calculate the food energy (joules/g) of one of your food
samples. one chemistry calorie is equal to 4.186 joules. convert the energy you
calculated to kilojoules (1 kj = 1000 j). since nothing is given, an example is
avocadoes have 160 cal/100 g serving
(160 cal/ 100 g)(4.186 J/ 1 cal) (1 kJ/1000 J) = 0.0067 kJ/g
