if a metal object was cut on half how much heat will be required to raise both half to a specific temperature
il63 [147K]

suppose the mass of a metal object be m and its specific heat capacity be s, and, H joules of heat is required to raise its temperature by t degrees Celsius

Than H is given by relation, H = mst

Now if this object is cut in two half's, than mass of half part will also be half <em>i.e. </em>M/2

So heat required to heat the half part will be = (\frac{m}{2}) st =\frac{mst}{2} = H/2  

Hence, the heat required to raise the half object to a specific temperature will also become half.

Given the frequency of an electromagnetic wave, what else can you find immediately?
Oksana_A [137]

Answer:

wavelength

Explanation:

An electromagnetic waves is produced due to interaction of oscillating electric and magnetic field when they interacts perpendicular to each other. For example, Gamma rays, X rays , ultraviolet rays, visible radiations, infrared rays, micro waves, radio waves.

All the electromagnetic waves have velocity equal to velocity of light.

If the frequency of electromagnetic wave is unknown then we find the wavelength of wave. the formula used is

Wave speed = wavelength x frequency
