Many physical quantities are connected by inverse square laws, that is, by power functions of the form f(x)=kx^(-2). In particul

goldenfox [79]

Answer:

4 times

Explanation:

Since the equation for the illumination of an object, i.e. the brightness of the light, is inversely proportional to the square of the distance from the light source, the form of the function is:

f(x) = k.x⁻²

Where x is the distance between the object and the light force, k is the constant of proportionality, and f(x) is the brightness.

Then, if you move halfway to the lamp the new distance is x/2 and the new brightness (call if F) is :

$F=k(x/2)^{-2}=\frac{k}{(x/2)^2}= \frac{k}{x^2}. 4=f(x).4$

Then, you have found that the light is 4 times as bright as it originally was.

SCORPION-xisa [38]

Answer:

$F=\rho_LAdg$

Explanation:

The buoyant force F is equal to the weight of the displaced fluid. The weight of the displaced fluid is $W=m_dg$ , where $m_d$ is the mass of the displaced fluid. The mass of the displaced fluid is $m_d=\rho_LV_d$ , where $\rho_L$ is the density of the fluid and $V_d$ is the displaced volume, which is equal to the submerged volume of the cilinder $V_d=V_s=Ad$ .

Putting all together we have:

$F=W=m_dg=\rho_LV_dg=\rho_LAdg$
