Answer:
Explanation:
Given:
- mass of aluminium,
- initial temperature of the aluminium cylinder,
- mass of coffee,
- initial temperature of coffee,
- specific heat of coffee (assuming water),
- specific heat of aluminium,
When the coffee and the aluminium cylinder come in contact then heat released by the coffee is equal to the heat gained by the aluminium.
<u>Mathematically:</u>
is the final temperature of agreement.
Yes. because if there is a direction taken positive and the object is accelerating negatively it can bounce of a wall and change its direction so through an obstruction can it do that
Answer:
They must have been traveling at 5333.33 km/h to cover that distance in 3 days.
That speed are 6,66 times higher than the speed of an aircraft jet.
Explanation:
d= 384000 km
t= 3 days = 3*24hr = 72hr
V= 384000km/72hr
V= 5333.33 km/h
comparison:
V1/V2= 5333.33/800
V1/V2= 6.66
The volume of the gas is
Explanation:
At standard temperature and pressure (stp), the volume occupied by 1 mole of an ideal gas is always equal to
In this problem, we have an amount of moles of gas of
n = 0.034 mol
Since 1 mol of gas occupies a volume of 22.4 L, we can set up the following ratio:
where V is the volume occupied by 0.034 mol of gas. Solving for V, we find
Or, in cubic metres,
