Andreyy89
Hello!

The garbage patchs are a site with high concentrations of trash. They are formed by the ocean gyre, where the ocean have convergences zones forming a circle of currents. When the garbage join the circle, it can't go out, cause the currents make a kind of a permanent "wall".

We can locate garbages patchs in the South Atlantic Gyre, Indian Ocean Gyre and the South Pacific Gyre.

Hugs!

2. If both the mass and radius of the earth, each decreases by 50%, the acceleration due to gravity would (a) remain same (b) de
Scrat [10]

Answer:

(d) increase by 100%

Explanation:

m_{i} = initial mass of earth = m

m_{f} = final mass of earth = (0.5) m

R_{i} = initial radius of earth = R

R_{f} = final radius of earth = (0.5) R

g_{i} = initial acceleration due to gravity of earth = g

g_{f} = final acceleration due to gravity of earth

initial acceleration due to gravity of earth is given as

g_{i} = \frac{Gm_{i}}{R_{i}^{2}}                             Eq-1

Final acceleration due to gravity of earth is given as

g_{f} = \frac{Gm_{f}}{R_{f}^{2}}                             Eq-2

Dividing eq-1 by eq-2

\frac{g_{i}}{g_{f}} = \frac{m_{i}}{m_{f}}\frac{R_{f}^{2}}{R_{i}^{2}}

inserting the values

\frac{g}{g_{f}} = \frac{m_{i}}{(0.5)m_{i}}\frac{(0.5)^{2}R_{i}^{2}}{R_{i}^{2}}

g_{f} = 2 g

So there is 100% increase
