FMRI creates the images or brain maps of brain functioning by setting up and utilizing an advanced MRI scanner in such a way that increased blood flow to the activated areas of the brain shows up on the MRI scan. The MRI scanners do not actually detect blood flow or other metabolic processes.
Q= mcΔT
Where Q is heat or energy
M is mass, c is heat capacitance and t is temperature
You have to convert Celsius into kelvin in order to use this formula I believe
Celsius + 273 = Kelvin
21 + 273 = 294K
363 + 273 = 636K
Now...
Q= (0.003)(0.129)(636-294)
Q= 0.132 J if you are using kilograms, in terms of grams which seems more appropriate the answer would be 132J of energy.
The wavelength of the wave which is travelling along right with speed of 0. 5 m/s time 4 second point is 2.
<h3>What is the speed of wave?</h3>
Speed of wave is the rate by which the wave travels. It can be described as the distance cover by the crest or thrust of it per unit of time. It can be calculated with the following formula,

Here, (f) is the frequency and (λ) is the wavelength.
The frequency is inverse of time. Thus, the value of frequency in time t is,

The speed of the wave is 0.5 m/s. Put the values in the formula,

Thus, the wavelength of the wave which is travelling along right with speed of 0. 5 m/s time 4 second point is 2.
