Answer:
Explanation:
Here by ideal gas equation we can say
now we know that pressure is kept constant here
so we will have
since we know that number of moles and pressure is constant here
so we have
now we know that initial temperature is 17.8 degree C
and finally volume is doubled
So we have
so final temperature will be
Answer:
Gravitational attraction is caused by the mass of an object. Since Earth is far more massive than the Moon, the gravitational force exerted on the Moon is far greater than that of the Moon on the Earth. An example of the difference: while the Moon causes tides on the Earth, the Earth has the Moon locked so that the same face (minus some wobbling) is always visible from the Earth
Explanation:
Answer:
1. Mass
2. Height
3. Gravitational Force Field
Explanation:
The three factors that decide how much gravitational potential energy a body has are: 1) The mass of the body itself, 2) The relative height at which the body is, because gravitational force varies with height i.e distance away from earth surface. 3) and finally the strength of the gravitational field the body is in.
Pressure = total force/total area
Total force = 660 Newton's
Total area:
Each leg contacts the floor with an area of πr^2=π(0.025m)^2=0.002m^2.
Total contact area for all 3 legs = 0.006 m^2.
Pressure = (660N) / (0.006 m^2)
= 110,000 N/m^2 = 110,000 Pascal's.
Answer:
C. The number of shells increases from top to bottom
Explanation:
There are some trends about the periodic table, one of them is that in the vertical columns of periodic table, the number of shells increases from top to bottom.
From top to bottom in a periodic table, the number of electrons increases, thus more number of shells are needed to fill these electrons and the number of shells increases or we can say the atomic radius increases from top to bottom.
Hence, the correct option is "C".
