Answer:
A)
B)
C)
Explanation:
For this case we want to create a function like this:
Where Z represent the degrees for the Z scale C the Celsius grades and tha valus a and b parameters for the model.
The boiling point of nitrogen is -195,8 °C
The melting point of iron is 1538 °C
We know the following equivalences:
-195.8 °C = 0 °Z
1538 °C = 1000 °Z
Let's say that one point its (1538C, 1000 Z) and other one is (-195.8 C, 0Z)
So then we can calculate the slope for the linear model like this:
And now for the slope we can use one point let's use for example (-195.8C, 0Z), and we have this:
And if we solve for b we got:
So then our lineal model would be:
Part A
The boiling point of water is 100C so we just need to replace in the model and see what we got:
Part B
For this case we have Z =100 and we want to solve for C, so we can do this:
Part C
For this case we know that
And we can use the result from part B to solve for K like this:
Answer:
time = 8.3333 minutes.
Explanation:
distance between earth and sun = 1.5 *
speed of light = 3*
convert the distance unit from km to m so we can have uniform units.
distance between earth and sun = 1.5 *m
distance between earth and sun = 1.5 * m
speed = distance /time
time = distance / speed
time =
time =500 sec
time = 500/60 minutes
time = 8.3333 minutes.
The current passing through a circuit consisting of a battery of 12 V and resistor of 2 ohms is 6 Ampere .
Explanation:
- Assume the wires are ideal with zero resistance.
- The current passing through the circuit will be
I = V/R = 12/2 = 6.000 A.
