Suppose we could shrink the earth without changing its mass..?At what fraction of its current radius would the free-fall acceler

Drupady [299]

Answer:

at R/ $\sqrt{3}$

Explanation:

The free-fall acceleration at the surface of Earth is given by

$g=\frac{GM}{R^2}$

where

G is the gravitational constant

M is the Earth's mass

R is the Earth's radius

The formula can be rewritten as

$R=\sqrt{\frac{GM}{g}}$ (1)

We want to shrink the Earth at a radius R' such that the acceleration of gravity becomes 3 times the present value, so

g' = 3g

Keeping the mass constant, M, and substituting into the equation, we have

$3g=\frac{GM}{R'^2}$

$R'=\sqrt{\frac{GM}{3g}}=\frac{1}{\sqrt{3}}\sqrt{\frac{GM}{g}}=\frac{R}{\sqrt{3}}$

The lower the temperature of the solvent, the faster the solute will dissolve. True False

denis23 [38]

Answer:

false.

Explanation:

Since temperature and kinetic energy of molecules are proportional, the more we increase the temperature of the solvent, the faster the solute will dissolve.

This increase of kinetic energy allows the solvent molecules to more effective break apart the solvent molecules that are held together by intermolecular forces.
