Answer: 270 km
Explanation:
3 cm/80 km :: 10 cm/(x)km
cross multiply
3x = 80(10)
x = 800/3 = 266.66666... ≈ 270 km
Answer:

Explanation:
Given that the temperature of
of water and
of water are
at
and
respectively.
Let
, 
and
,
.
The specific heat capacity of water is,
.
Let the final temperature of the mixture be
.
As there is no energy loss, so, the energy loss by the water at higher temperature, i.e.
, will be equal to the energy gain by the water at lower temperature, i.e.
.

[ both sides divided by
]



Now, putting the given value in the above equation, we have


Hence, the temperature of the mixture will be
.
Answer:
a)The volume is reduced to one-third of its original value.
Explanation:
For a gas at constant temperature, we can apply Boyle's law, which states that the product between pressure and volume is constant:

where p is the pressure and V the volume.
In our case, this law can also be rewritten as

where the labels 1 and 2 refer to the initial and final conditions of the gas.
For the gas in the problem, the pressure of the gas is tripled, so

And re-arranging the equation we find what happens to the volume:

so, the volume is reduced to 1/3 of its original value.
