So, the temperature of a wave that has a wavelength of 5 m is
<h3>Introduction</h3>
Hi ! Here, I will help you to explain about The relationship between temperature and electromagnetic wavelength uses the principle of Wien's Constant. According to Wien, <u>if we multiply temperature with the electromagnetic wavelengths will always got the same number (constant)</u>. Therefore, The relationship is expressed in this equation :
With the following condition :
- C = Wien's constant ≈
- = wave at its longest point (m)
- T = absolute temperature (K)
<h3>Problem Solving</h3>
We know that :
- C = Wien's constant ≈
- = wave at its longest point = 5 m
What was asked :
- T = absolute temperature = ... K
Step by step :
<h3>Conclusion :</h3>
So, the temperature of a wave that has a wavelength of 5 m is
Wavelength =(speed)/(frequency)
Wavelength =(20 m/s) / (20/s)
Wavelength = 1 meter
If the speed<span> of the </span>object<span> becomes </span>double<span>, </span>its kinetic energy<span> changes to four times the initial </span>kinetic energy<span>. Hope it help!</span>
Answer:
Explanation:
It is given that,
Mass of the loop, m = 10 g = 0.01 kg
Resistance of the loop, R = 0.02 ohms
Dimension of square loop, 7 cm × 7 cm
Area of the loop,
At time t = 0 s, the magnetic field increases from 0 to 1 T in 0.01 s
(a) Due to change in magnetic field, an emf is induced in the loop. Using the formula for induced emf as :
Now using Ohm's law to find the induced current in the loop. It is given by :
I =24.5 A
(b) A magnetic force acting on the loop is given by :
F = 0.8575
Since,
v = 0.8575 m/s
Hence, this is the require solution.
The speed is 0.956 m / s.
<u>Explanation</u>:
The kinetic energy is equal to the product of half of an object's mass, and the square of the velocity.
K.E = 1/2 m
where K.E represents the kinetic energy,
m represents the mass,
v represents the velocity.
K.E = 1/2 m
1.10 10^42 = 1/2 3.26 10^31
= (1.10 10^42 2) / (3.26 10^31)
v = 0.956 m / s.
