<h3><u><em>Answer:</em></u></h3><h3><u><em>Ok, here we go...</em></u></h3><h3><u><em>Explanation:</em></u></h3><h3><u><em>Astronauts perform many tasks as they orbit Earth. The space station is designed to be a permanent orbiting research facility. Its major purpose is to perform world-class science and research that only a microgravity environment can provide. The station crew spends their day working on science experiments that require their input, as well as monitoring those that are controlled from the ground. They also take part in medical experiments to determine how well their bodies are adjusting to living in microgravity for long periods of time.</em></u></h3><h3><u><em></em></u></h3><h3><u><em>Working on the space station also means ensuring the maintenance and health of the orbiting platform. Crew members are constantly checking support systems and cleaning filters, updating computer equipment: doing many of the things homeowners must do to ensure their largest investment stays in good shape. Similarly, the Mission Control Center constantly monitors the space station and sends messages each day through voice or email with new instructions or plans to assist the crew members in their daily routines.</em></u></h3><h3><u><em></em></u></h3>

A physicist is calibrating a spectrometer that uses a diffraction grating to separate light in order of increasing wavelength (λ
cluponka [151]

Answer:

Explanation:

Given

N=3680 cm^{-1}

therefore slit spacing d=\frac{1}{N}=\frac{1}{3680}=2.717\times 10^{-4}\ cm

since d\sin \theta =n\lambda

for n=1

d\sin \theta =\lambda

Now,at \theta _1=12.9^{\circ},\Rightarrow \lambda _1=6.0657\times 10^{-7}\ m=606.57\ nm

at \theta _2=14.2^{\circ}\Rightarrow \lambda_2=666.5\ nm

at \theta _3=15^{\circ}\Rightarrow \lambda_3=703.21\ nm

The capacity of the air to hold water vapor: Group of answer choices 1. decreases with an increase in temperature.2. increases w
Nezavi [6.7K]

Answer:

3. increases with an increase in temperature.

Explanation:

The air more water vapor at higher temperatures because at higher temperatures the air expands and the inter-molecular space increases so the room for water molecules increases.

Warm air keeps the water molecules warm and prevents them from condensing.

The air can hold the moisture only upto its saturation quantity after which the precipitation occurs in the form of rain, snow, hail, sleet etc.
