The definition of speed is (distance covered) / (time to cover the distance) .
So a unit of speed has to be (a unit of length) / (a unit of time) .
Here are several perfectly fine units of speed:
-- miles per hour
-- feet per second
-- meters per second
-- kilometers per hour
-- inches per second
-- centimeters per minute
-- yards per Century
-- furlongs per fortnight
-- nanometers per microsecond
-- Smoots per week
-- parsecs per millenium
Answer:
Shorter the wavelength, the higher the frequency of the electromagnetic wave, and greater is the energy of the waveform or the photon. Frequency is always inversely related to the wavelength.

Answer:
Technician A
Explanation:
It is seen that a tire pressure will increase or decrease 1 psi for each change in temperature.
For Technician B vehicle pressure should not be adjusted after tire has been warmed as the warm air may increase the pressure but it will be auto adjusted as the temperature falls to normal .
Answer:
The period of the orbit is 12163.649 seconds.
Explanation:
What quantity are you looking for? I'll assume it's the orbital period.
The period, P, of an orbit in seconds is found from
P = 2π √[a³/(GM)]
where
a = the semimajor axis of an elliptical orbit, or the radius of a circular orbit
G = 6.67428e-11 m³ kg⁻¹ sec⁻²
M = the sum of the masses of Mars and the satellite
The mass of the satellite is presumably negligible.
M = 6.4191e+23 kg
a = 1.6 Rmars = 1.6 (3.397e+6 meters) = 5435200 m
Therefore,
P = 12163.649 sec
An atom is defined as having the same number of electrons (negative charge), protons (positive charge) and neutrons (no charge). This means that it will have the same amount of negative and positive charge, giving it a net zero charge. On the other hand, an ion has different amount of electrons and protons.
