While the frequency increases, the wavelength decreases
Start here:
1. White light undergoes
when it passes through a prism.
2.
is also considered as a luminous body (an object capable of producing its own light).
3.
that which is detectable by the human eye consists of wavelengths ranging from
approximately 780 nanometer (7.80 x 107 m) down to 390 nanometers (3.90 x 107 m).
4. The long-wavelength end of the spectrum corresponds to light that is perceived by humans to be
and the short-wavelength end of the spectrum corresponds to light that is perceived to be
5. The product of frequency and wavelength in all color lights is constant and equal to the
6. The speed of all color light in air is constant and is equal to the​

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.

explanation:

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
