• ThankYOU, do think you would wanna explain any of the answers?

• Show All
• Electricity, magnetics and heat conduction are physical properties.

mili is unit of measurement 1000 times smaller than it's main measurement. Main measurement for mass is gram, this means 1000 miligrams is 1 gram. So 2500mg is 2,5 g.

Basic equation, if 300=C+273 then C=300-273.

Lenght is in meters, Density in kg/m3 , mass in kg and volume in liters (1dm3).

• by the way it's 27 not 17. 3) is b.
