Answer:
290 N
Explanation:
Total downward force = Force applied on the door in bringing it down + weight of the door
Total downward force = 80 + 210
Total downward force = 290N
Ke=(1/2)mv^2, add up the mass of one carbon and two oxygen times it by velocity^2, divide by 2
CH2O3
C=19.36\12 = 1.61
H=3.25\1.008 =3.22
O=77.39\16=4.83
then dived the moles with the smallest mole
C=1.61\1.61=1
H=3.22\1.61=2
O=4.83\1.61=3
E.F
CH2O3
Yes the particles are larger than 10,000 Angstroms which allow it to be separated by filtration
Answer:
Explanation:
Given that,
The dimension of a square chunk of plastic is 5 cm × 5 cm × 5 cm
Mass, m = 200 g
We need to find its density
Density = mass/volume
It will form a cube. It volume = side³
So,
Hence density is
