Answer:
Explanation:
First of all, we have to calculate the heat released by the steam whem it turns into liquid water. This is given by:
where
is the mass of steam
is the latent heat of vaporization
Substituting,
Now we find the heat absorbed by the ice when it turns into liquid water:
where
is the mass of ice
is the latent heat of fusion
So,
Then, we call:
the heat absorbed by the ice (now liquid water) till reaching the equilibrium temperature T, where
is the specific heat capacity of water
the heat released by the steam (now liquid water) till reaching the equilibrium temperature T
Since the total heat absorbed must be equal to the total heat released, we have:
And now we can solve to find T:
Work= F times d so force x distance
25(.5) is 12.5
Answer:
Explanation:
Let four particles are placed on X axis symmetrically about the origin and M is placed on y axis.
According to the diagram, the x component of forces balances each other and the net force acting on the particle of mass m is acting in the direction of negative Y axis.
Answer:
9833333.33 years
Explanation:
Speed of the land = 6 cm/y = v
Convert the speed to km/y
1 km = 10000 m
⇒1 m = 1/10000 km
⇒1 m = 10⁻⁵ cm
So,
6 cm/y = 6×10⁻⁵ km/y
Distance the land will travel = 590 km = s
Time taken
∴ Time taken by the land to move 590 km is 9833333.33 years.
