Answer:
According to mass and volume, block density is 2 g/ml
Explanation:
Density is a measure, usually used in physics and chemistry, that relates the mass and volume of a solid or compound.
In general terms, the density is directly proportional to the mass, and inversely proportional to the volume, so increasing the mass will also increase the density.
The formula used to calculate the density is
ρ = 
Therefore, according to the mass and density of the block
ρ =
= 2g/ml
Being the density of the block equal to 2 g/ml.
<em>The other options are not possible, because the values given do not correspond to the result of the equation.</em>
Answer:
Yes
Explanation:
I just quickly looked it up. Cornstarch is extremely flammable.
Answer:
Its mass is measured on a scale.
It is measured on a balance.
Explanation:
The mass of an object can easily be determined using a balance or weighing scale.
Mass is the amount of matter contained in a substance. it is has the same value every where and will not vary by geography or location.
Weight is the force on body due to gravity. It is a function of mass and acceleration due to gravity.
Both mass and weight are different.
They can both be measured using a weight device.
