Answer:
it increases by a factor 1.07
Explanation:
The peak wavelength of an object is given by Wien's displacement law:
(1)
where
b is the Wien's displacement constant
T is the temperature (in Kelvins) of the object
given the relationship between frequency and wavelength of an electromagnetic wave:
where c is the speed of light, we can rewrite (1) as
So the peak frequency is directly proportional to the temperature in Kelvin.
In this problem, the temperature of the object changes from
to
so the peak frequency changes by a factor
Answer:
Thermal and internal energy is equal to the sum total kinetic energy possessed by the the molecules whereas the heat energy is the transfer of thermal energy from high temperature to low temperature.

Answer:
The incidence angle is 27°
Explanation:
As the complete question is not given, the complete question is given here
<em>The angle between the Sun and a rescue aircraft is 54 degrees. What should be the angle of incidence for sunlight on a plane mirror so that the rescue pilot sees the reflected light?</em>
From the question, the total angle between the Sun and the aircraft is 54 degrees which is the sum of the incidence and the reflected angle so
Also from the law of reflection
So now the equation becomes
So the incidence angle is 27°
