Radiator. A radiator puts warm air out at the top and draws in cooler air at the bottom. steaming cup of hot tea - The steam you see when drinking a cup of hot tea indicates that heat is being transferred into the air. ice melting/Ice melts because heat moves to the ice from the air
A.) more weight lighting weights
If you've ever seen the formula from Celsius to Fahrenheit...
As you can see, if you put in some number of Celsuis C your answer is going to be multiplied by 5/9...meaning that 1°C = 5/9°F.
As for Kelvin, it's literally just Celsuis, but about 273.15° more.
B. 5/9°F
Answer:
The answer is: 212.3112
Explanation:
-First we need to know that if we want to push in order for the sled to move with constant velocity so there is no acceleration and hence the sum of forces is equal to 0.
-Second we need to know:
Friction force = Normal Force x kinetic friction
Normal force = Weight x cos(21°)
-Third:
Finally:
Answer:
Explanation:
The flow entering the first segment will be the same as the flow exiting the second segment, and in both cases it will be equal to the velocity multiplied by the area of the segment. If and Flow = VxA, then you have:
(1)
You can also calculate the transversal area of each segment, because blood vessels are cylinders and you know each segment's diameter. The formula to calculate this is:
Replacing d for each segment you have:
Now, replacing these values on (1), you have:
This means that velocity in the second segment is 15.4 times the velocity in which blood entered the first segment.
