Explanation:

It is known that the specific heat capacity of Liver (C_{p}) is 3.59 kJ kg^{-1}.K^{-1}

It is given that :

Initial temperature of Liver = Body temperature = 37^{o}C = 310 K

Final temperature of Liver = 180 K

Relation between heat energy, mass, and change in temperature is as follows.

                        Q = m \times C_{p} \times \Delta T

Now, putting the given values into the above formula as follows.

                    Q = m \times C_{p} \times \Delta T

                    Q = 1.5 kg \times 3.59 kJ/kg.K \times (310 - 180) K

                         =  700.05 kJ

Therefore, we can conclude that amount of heat which must be removed from the liver is 700.05 kJ.

What is the speed of a man that travels 2 meters in 6.5 seconds?
sergij07 [2.7K]

Answer:

0.305556 m / s

Explanation:

Speed = distance / time

2 metres = 0.002 km

6.5 sec = 0.00180556 hrs

Therefore,

Speed = 0.002 / 0.00180556

           =  1.1 km / hr

           = <u>0.305556 m / s</u>

Do radio waves and microwaves have longer or shorter wavelengths than visible light?
lesya [120]
Radio and microwaves have longer wavelengths than visible light.

If you go take a look at the electromagnetic spectrum, you will be able to see that visible light waves have a higher frequency and a shorter wavelength (10^{-6}).
