Answer:
Consciousness at its simplest is "sentience or awareness of internal or external existence" Well as unconsciousness is not being awake.
Ex: asleep, knocked out, ect.
Answer:
51.82
Explanation:
First of all, let's convert both vectors to cartesian coordinates:
Va = 36 < 53° = (36*cos(53), 36*sin(53))
Va = (21.67, 28.75)
Vb = 47 < 157° = (47*cos(157), 47*sin(157))
Vb = (-43.26, 18.36)
The sum of both vectors will be:
Va+Vb = (-21.59, 47.11) Now we will calculate the module of this vector:
Answer: 5289 joules
Explanation:
The quantity of Heat Energy (Q) required to heat a substance depends on its Mass (M), specific heat capacity (C) and change in temperature (Φ)
Thus, Q = MCΦ
Since, Mass of ice = 20 g
C is not provided (Recall that the specific heat capacity of ice is 2.010J/g°C)
Φ = (Final temperature - Initial temperature)
(120°C - (-25°C) =
120°C + 25°C = 145°C
Thus, Q = 20g x 2.010J/g°C x 145°C
Q= 5829J
Thus, 5829Joules of heat energy is required to heat ice
