Explanation:
a) 7.5= 111.1×2°= 0.1111×2^3
which can also be written as
(1/2+1/4+1/8+1/16)×8
sign of mantissa:=0
Mantissa(9 bits): 111100000
sign of exponent: 0
Exponent(5 bits): 0011
the final for this is:011110000000011
b) -20.25= -10100.01×2^0= -0.1010001×2^5
sign of mantissa: 1
Mantissa(9 bits): 101000100
sign of exponent: 0
Exponent(5 bits): 00101
the final for this is:1101000100000101
c)-1/64= -.000001×2^0= -0.1×2^{-5}
sign of mantissa: 1
Mantissa(9 bits): 100000000
sign of exponent: 0
Exponent(5 bits): 00101
the final for this is:1100000000100101
Answer: leftover radiation from the big bang
Microwave background radiation is a form of electromagnetic radiation that is present in the whole universe and completely fills it.
Its frequency belongs to the microwaves range and is one of the main demonstrations of the of the Big Bang theory model.
It is important to note the Big Bang occurred 400,000 years before the events related to the microwave cosmic radiation, this means the Big Bang occurred first.
The heat (energy) needed to raise the temperature of the water is given by
The wavelength of the radiation of the oven is
, so the energy of a single photon of this radiation is
So, the number of photons required to heat the water is the total energy absorbed by the water divided by the energy of a single photon:
photons
Those are all "acceleration", caused by
unbalanced forces acting on the object.
