Will give brainliest! Please help me :( How does the melting of ice caps near the North Pole affect the salinity of the ocean?
Salinity decreases because freshwater flows into the ocean.
Salinity increases because of the stored pockets of air and salt.
Salinity increases because salt from the ice caps flows into the ocean.
There is no change in the ocean’s salinity with this process.

What is the mass of the same rock on the earth

An object resting on a table weighs 100 n. with what force is the object pushing on the table? with what force is the table pushing on the object? explain how you got your answer.

Antireflective coatings on solar cells are often made by applying a thin film of silicon nitride (sinx), which has an index of refractive of 1.2, on the top of the silicon solar cell, which has a refractive index of about 3.5. however, the sun emits radiation of various wavelengths which the solar cell absorbs, and the antireflective coating can only absolutely minimize the reflection of one of these wavelengths. the coating thickness is chosen to reduce the reflection of green/yellow light (e = 2.2 ev), which is the most intense color in the solar spectrum (shown below). which of the following coatings would minimize reflection of green/yellow light? the answer is 820 nm how? what is the angular width of the central maximum of an electron traveling at 2 x 108 m/s going through a single slit of width 1 mm.
