Answer: (a) The magnitude of its temperature change in degrees Celsius is .
(b) The magnitude of the temperature change (change in T = 15.1 K) in degrees Fahrenheit is .
Explanation:
(a) Expression for change in temperature is as follows.
= 15.1 K
=
=
=
Therefore, the magnitude of its temperature change in degrees Celsius is .
(b) Change in temperature from Celsius to Fahrenheit is as follows.
F = 1.8C + 32
C =
Since, K = C + 273
or,
= 1.8 (15.1)
=
or, =
Thus, we can conclude that the magnitude of the temperature change (change in T = 15.1 K) in degrees Fahrenheit is .
Explanation:
Speed is the rate of change of distance with time. It is a scalar quantity with magnitude both no direction.
Speed =
The unit is m/s or km/hr or mile/hr
Distance covered is simply the length of the path traveled.
The unit is m or km or miles
