Answer:
it loses its momentum. In simpler ways it is really slow
Explanation:
Answer:
a. C(F) = (5/9).F - (160/9)
b. They both readings are equal at C = F = - 40
Explanation:
They are telling us that we are looking for a linear function
If C(F) = a.F + b is the linear function, we use the data to find a and b
C(32) = a.32 + b
0 = a.32 + b
b = - (a.32) (1)
And then
C(212) = a.212 + b
100 = a.212 + b (2)
replacing (1) in (2) we obtain
100 = a.212 + [-(a.32)]
100 = a.212 - a.32
100 = 180.a
a = 100/180
a = 5/9
If a = 5/9 then b = -(a.32)
b = - (5/9).32
b = - (160/9) and the linear function is
C(F) = (5/9).F - (160/9)
For b. they are asking us for a X reading. We must equalize C and F
X = (5/9).X - (160/9)
(4/9).X = - (160/9)
X = -40
C = F at temperature X = - 40
Answer:
a) 
b)
Explanation:
First we convert our minutes to hours so we work always in the same units.
Where we used the fact that 1 hour are 60 min, thus the multiplying factor is equal to 1 (not altering the time, just changing the units).
a) On the first part the motorist travels a distance 
, and on the second part he travels 
.
The total displacement is 
b) The average velocity is the relation between the total displacement and the time taken to cover it. Our total time is t=0.6h+0.25h+2.2h=3.05h, thus we have:
Answer:
The induced current will be counterclockwise.
Explanation:
Magnetic field lines always begin on north poles and end on south poles. This means that there is an increase of magnetic field lines going into the plane of the loop. The induced current will be counterclockwise to oppose this change.
