An electric current through hydrogen gas produces several distinct wavelengths of visible light. What are the wavelengths of the hydrogen spectrum, if they form first-order maxima at angles of 24.2-degrees, 25.7 degrees, 29.1 degrees, and 41.0 degrees. when projected on a diffraction grating having 10,000 lines per centimeter.

explanation:

wind is defined by the direction it blows from.   for example, a wind blowing from north to south is called a northerly wind.

the area between the graph and the t axis

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
