Astudent designed an experiment to demonstrate the interaction between earth systems. the steps of the experiment are given below. take a pot full of dry soil. keep the pot in direct sunlight. do not water the soil for a week. observe cracks in the soil after a week. the student's experiment demonstrates the select one: a. interactions between the geosphere and hydrosphere during a tornado b. interactions between the atmosphere and geosphere during a drought c. interactions between the hydrosphere and atmosphere during a hurricane d. interactions between the hydrosphere and cryosphere during a thunderstorm

Wavelength,frequency,and energy are related.what happens to a wave as it’s wavelength gets shorter?

Which statement correctly describes the current in a circuit that is made up of any two resistors connected in parallel with a battery? a. the current in the battery and in each resistor is the same b. the current the battery equals to the sum of the currents in the resistors c.the current in the battery is less than the current in either resistor d. the current in the battery equals to the product of the currents in the resistors

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.
