Determine Heat flux due to convection
answer : 16 w/m^2
Explanation:
Room temperature = 24°c
Room temperature during summer = 26°c
Room temperature during winter = 16°c
surface temp of person = 32°C
emissivity = 0.90
coefficient ( h ) = 2 W/m2.K
Determine Heat flux due to convection
Q" = h ( Δ T ) = coefficient * ( surface temp of person - room temperature )
= 2 * ( 32 - 24 ) = 16 w/m^2

Explanation:
A communications system transmits a message. The probability that the message will be received is p. To be confident that a message is received at least once, the system transmits it n times. If a message is received, the receiver turns off and does not turn back on.
a. Assuming all transmissions are independent, what is the PMF of K, the number of times the pager receives the same message?
b. Assume p=0.8. What is the minimum value of n that produces a probability of 0.95 of receiving the message at least once?
Answer:
Follows are the solution to the given points:
Explanation:
In point a:
In the PMF of K, that pager receives its same message number of times, that is [tex]=\tiny \binom{n}{k}p^{k} (1-p)^{n-k}[/tex]
In point b:
The possibility of getting number of cultural at least once in x:
[tex]\to 1-P(\text{not receiving it at all})\\\\\to 1-(0.2)x\\\\\to 1-(0.2)x>0.95\\\\\to (0.2)x<0.05 \\\\[/tex]
appling the [tex]\log[/tex]:
[tex]\to x>0.25[/tex]
The value x is equal to 3.

True or False; If I was trying to find the Voltage of my computer, and I was given the Watts and Amps it uses, I would use Watt's Law.
Answer:
true
Explanation:
An automobile having a mass of 1100 kg initially moves along a level highway at 120 km/h relative to the highway. It then climbs a hill whose crest is 80 m above the level highway and parks at a rest area located there. Use a reference with kinetic and potential energy each equal to zero for the stationary highway before the hill. Let g = 9.81 m/s^2.
For the automobile, determine its change in kinetic energy and its change in potential energy, both in kJ. For the automobile, determine its change in kinetic energy, in kJ.
a. -8594
b. -663.1
c. -6.63x10^5
d. 663.1
Answer:
[tex]-6111.11\ \text{kJ}[/tex]
[tex]863.28\ \text{kJ}[/tex]
Explanation:
m = Mass of automobile = 1100 kg
v = Velocity of car = 120 km/h = [tex]\dfrac{120}{3.6}\ \text{m/s}[/tex]
h = Height of hill = 80 m
g = Acceleration due to gravity = [tex]9.81\ \text{m/s}^2[/tex]
Change in kinetic energy
[tex]KE=\dfrac{1}{2}m(u^2-v^2)\\\Rightarrow KE=\dfrac{1}{2}\times 1100\times (0-(\dfrac{120}{3.6})^2)\\\Rightarrow KE=-611111.11\ \text{J}[/tex]
Change in kinetic energy is [tex]-6111.11\ \text{kJ}[/tex]
Change in potential energy is given by
[tex]PE=mgh\\\Rightarrow PE=1100\times 9.81\times 80\\\Rightarrow PE=863280\ \text{J}[/tex]
The change in potential energy is [tex]863.28\ \text{kJ}[/tex].

Merchandise without an expiration date like electronics, tools and home goods typically have a longer
Answer:
Shelf life.
Explanation:
In Business, an inventory is a term used to describe a list of finished goods, goods still in the production line and raw materials that would be used for the manufacturing of more goods in a bid to meet the unending consumer demands.
Simply stated, an inventory can be classified into three (3) main categories; finished goods, work in progress, and raw materials.
An inventory is recorded as a current asset on the balance sheet because it's primarily the most important source of revenue for a business entity.
Also, the three (3) main cost concept associated with an inventory are;
1. First In First Out (FIFO).
2. Last In First Out (LIFO).
3. Weighted average cost.
Shelf life can be defined as a measure of the length of time that a particular product could be kept or stored without it getting bad or becoming unsuitable for use by the consumers. Thus, the shelf life of a product is largely dependent on its expiration date.
Hence, merchandise without an expiration date like electronics, tools and home goods typically have a longer shelf life.
