Answer:
a) -35.6°C
b) 237.4 K
Explanation:
To convert temperature from degree celsius to degree fahrenheit, use the formula below:

a) Therefore to convert -32°F to celsius, substitute it into the celsius

b) To covert to the Kelvin scale, use the formula below
A blackbody curve represents the relation between <u>intensity of radiation with wavelength.</u>
Here in this curve we can see that all ideal blackbody radiates almost all wavelength of radiations and these radiations are of different intensity.
here intensity will be maximum for a given wavelength of radiation and the relation of this wavelength with the temperature of the object is given by Wein's law
It is given by

now if we increase the temperature the maximum intensity for which wavelength is given will shift to the left.
Using this all we can also compare the temperature of two blackbody for which radiation graph is given to us.

It is important to wear protective equipments during games and practices.
Explanation:
Practice is a review of what is about to happen in some time to come and with practice ,the future can be trusted.
During practice it is very important to use protective gears or equipments because without them, injuries and accidents are liable to occur.

Answer:
C.
Explanation:
If there are the same number of protons (+) as electrons (-) they will cancel out and make the atom neutral.
Answer:
0.82 MPa
Explanation:
the change in pressure 'σ'=160kPa
K= σ/∈
=> σ/3∈
K= 160/(3 x 0.065)
K=820 kPA=0.82 MPa
Thus,the bulk modulus of the tissue 'K' is 0.82 MPa
