The amount of Protein intake is 900 kilocalorie.
We have - 2000 Kilocalories of diet and 45 Percent of calories come from Proteins.
Wе have to find out the amount of protein intake.
<h3>If ' x ' students out of total ' n ' students in a class are infected by virus. Then, what percentage of students are infected.</h3>Percentage of students affected are -
In the question given -
Let the amount of Protein intake be y.
Then -
45 = y % of 2000
45 =
y =
y = 900 Kilocalorie
Hence, the amount of Protein intake is 900 kilocalorie.

The dP/dt of the adiabatic expansion is -42/11 kPa/min
<h3>How to calculate dP/dt in an adiabatic expansion?</h3>An adiabatic process is a process in which there is no exchange of heat from the system to its surrounding neither during expansion nor during compression
Given b=1.5, P=7 kPa, V=110 cm³, and dV/dt=40 cm³/min
PVᵇ = C
Taking logs of both sides gives:
ln P + b ln V = ln C
Taking partial derivatives gives:
Substitutituting the values b, P, V and dV/dt into the derivative above:
1/7 x dP/dt + 1.5/110 x 40 = 0
1/7 x dP/dt + 6/11 = 0
1/7 x dP/dt = - 6/11
dP/dt = - 6/11 x 7
dP/dt = -42/11 kPa/min
Therefore, the value of dP/dt is -42/11 kPa/min
