1. Height of cube =9cm
mass of cube= 3645 g
volume= length ×breadth× height
as cubic volume so length breadth and heights are same so
volume =height ×height ×height
V =9cm×9cm×9cm= 729cm³
density =mass/ volume
density =3645g/729cm³
density= 5g/cm³
2. AS DENSITY = mass/volume
volume =mass/ desity
volume= 13.558g/(0.089g/l)
volume= 0.152L³
6 cubic feet I’m pretty sure that’s the answer
evaporation (if that's to fill in the blanks question)
Answer: hello your question is poorly written attached below is the complete question
answer :
TA = 1.6*10^-24 * 60 * 2, TB = 1.6*10^-24 * ( 60 + 30 ) * 2 -- ( option 1 )
Explanation:
a = 2m/s^2
Ta = m₁ a = 60 * 1.6 * 10^-24 * 2 ц
Tb - Ta = m₂ a
∴ Tb = m₂ a + Ta
= ( 30 * 1.6 * 10^-24 * 2 ) + ( 60 * 1.6 * 10^-24 * 2 )
= ( 30 + 60 ) * 1.6 * 10^-24 * 2 ц
