The density of sodium is 968 g/cm3. Suppose you need 250 gm of sodium for an experiment. Which volume of sodium do you need?
Masja [62]
The formula for the density of a substance expressed in mass and volume is rho = mass/volume or p = m/v. Rearranging the formula to isolate volume gives the formula v = m/p. To solve for the problem given, this formula must be used. This gives a solution of:

v = m/p = 250 g/ 968 g/cm^3 = 0.258 cm^3 of sodium

7 Consider two homogeneous bodies of
kupik [55]

Answer:

No, it is not necessary for them to have same mass.

Explanation:

Let both bodies have a density d1 and d2 respectively.

Since their volumes are equal V1 = V2

we know that,

density = \frac{mass}{volume}

Hence, d1 = \frac{m1}{V1} and d2 = \frac{m2}{V2}  

Taking the ratio of densities,we get

\frac{d1}{d2} = \frac{m1}{m2}

This implies that unless the bodies have same densities, the mass of the two bodies will not be same.

Which of Newton’s laws explains why your hands get red when you press them hard against a wall.
ANTONII [103]

Answer:

Newton's third law, if i'm not mistaken.

Explanation:

Any action that occurs will have a opposite and equal action. The greater the force u apply to the wall, the greater the force the wall exerts back at you, hence why ur hands become red if u try pushing extremely hard on the wall.
