Answer:
final volume = 640 ml
Explanation:
To answer this question, we will use Boyle's law which states that:
"At constant temperature, the product of the pressure and the volume of a given mass of gas will be constant"
Thereore:
P1V1 = P2V2
800*560 = 700*V2
V2 = 640 ml
Hope this helps :)
Answer:
Isentropic compression in a pump, Constant heat addition in a boiler, Isentropic expansion in a turbine, constant heat rejection in a condenser
Explanation:
Ideal rankine cycle schematic diagram and T-S diagram is shown in below figure
The process 1-2 is isentropic compression is taking place in pump.
The process 2-3 is constant heat addition, heat addition takes places at boiler.
The process 3-4 is isentropic expansion, is taking place is turbine.
The process 4-1 is constant heat rejection , takes place in condenser.
Answer:
a)801KJoules
b)The woman must climb stairs for an equivalent of 1.57km
Number of stairs=7850 stairs
Explanation:
a)We use the conversion between Joules and Kcal:
4184Joules=1Kcal
540Kcal*(1484Joules/1Kcal)=801KJoules
b)The physical Work must be equal to the food energy
The woman must climb stairs for an equivalent of 1.57Km
For example if an stair measure 20cm=0.2m
Number of stairs=1.57km/0.2m=7850 stairs
Answer:
Velocity will be
Explanation:
We have given mass of alpha particle m = 4 u
Charge on alpha particle
Charge on thorium particle
Diameter is given as d = 15 fm
So radius
Potential energy is given by
From energy conservation
WARMER AND WETTER BIOMES GENERALLY HAVE MORE PLANTS, WHICH NEED MORE SUNLIGHT. THE SUNLIGHT CONTRIBUTES TO THE HIGHER NET PRODUCTIVITY
