Answer:
Since the wire is not splitting at any point in the circuit,
the resistors are in series
Hence, Equivalent resistance = 10 + 20 + 30
Equivalent Resistance = 60 Ω
The heat moves from the hot chocolate to the handle of the spoon by a process called thermal conduction.
It is the transfer of heat energy from one object to another when they are in contact with eachother.
Hope this answers your question.
Answer: 271.4 s
Explanation:
We are told the top speed (maximum speed) 
the car has is:
taking into account 
And the car's average acceleration 
is:
Since:
(1)
Where:
is the car's final speed (top speed)
because it starts from rest
is the time it takes to reach the top speed
Finding this time:
(2)
(3)
(4)
Now we have to find the distance 
the car traveled at this maximum speed with the following equation:
(5)
Isolating :
(6)
(7)
(8)
On the other hand, we know the total distance 
traveled by the car is:
Hence the remaining distance is:
(9)
(10)
So, we can calculate the time 
it took to this car to travel this remaining distance 
at its top speed , with the following equation:
(11)
Isolating :
(12)
(13)
(14)
With this time and the value of 
calculated in (4) we can finally calculate the total time 
:
(15)
(16)
Without condensation, the water vapor could not turn into clouds and liquids then which means it could not fall back down through things like rain or hail. Eventually, all water on earth would then become water vapor and we wouldn't have any water in liquid form.
