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 <em>inversely proportional to the square of the distance from the light source</em>, 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
