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:
Explanation:
It is given that,
The planet Mercury travels in an elliptical orbit with eccentricity 0.206, e = 0.206
The minimum distance from the sun,
The relation between the minimum and the maximum distance from the sun is given by :
a is the maximum distance from the sun
or
So, the maximum distance from the sun is . Hence, this is the required solution.
Answer:
<h3>
steam point</h3>
The upper fixed point, or steam point, is the temperature of pure boiling water at normal atmospheric pressure. Note that the fixed points are defined using common physical phenomena so that they can be easily reproduced.
Answer: Reflection is the only process in which the wave does not continue moving forward.
Explanation:
Reflection is a process in which the direction of the wave changes when it is exposed to a bounce off barrier. Refraction can be defined as the change in the direction of the wave when the wave passes through one medium to another. Diffraction is a process in which the direction of the wave changes when the wave passes through a particular opening near the barrier.
Answer:
A. Drag
Explanation:
This is because, since friction tends to oppose the motion of an object, and drag affects an object moving in a fluid, the more the friction, the more the drag on the object.
