First of all, this is the chemistry section, while your question is a physics question. Anyway I'll tell you how to solve it.
First we need to find the rate that the truck moves in a second.
1km = 1000m
40km = 40000m
40000m/hr
1 hour = 60 minutes
40000m/hr ÷ 60 = 666.66(repeating)/minute
1 minute = 60 seconds
666.66m/min ÷ 60 = 11.11(rep)m/s
Next we simply multiply the speed of the truck by the number of seconds it travels.
11.11 × 5 = 55.55
Make sure to round it unless you indicate the repeating decimal.
The truck moved 55.56m in 5 seconds.
Answer:
B). Allow efficient gathering of unobservable phenomena.
Explanation:
Surveys are described as the method of gathering information from a specified group of respondents for purposes like research or assessment of the truth of thoughts or opinions associated with a process.
As per the question, one of the most considerable benefits of the survey is that 'it allows the efficient gathering of unobservable phenomena'. The data associated with phenomena like stated preferences, behaviors, beliefs, and factual information are unobservable and can not be collected through observation but surveys help in doing so as well as in the assessment of the validity or reliability of the existing propositions about such phenomena. Thus, <u>option B</u> is the correct answer.
Answer:
= -4.2°C
= 49.4°C
Explanation:
A Carnot cycle is known as an ideal cycle in thermodynamic. Therefore, in theory, we have:
|
| = 
Similarly,
|
| = |
| + |
|
During winter, the value of || = 20°C = 273.15 + 20 = 293.15 K and || = 1.5 kW. Therefore,
|| = 0.75( - )
Similarly,
|
| = 1 -
1.5/0.75*(293.15-) = 1 - (/293.15
Further simplification,
= -4.2°C
During summer, = 25°C = 273.15+25 = 298.15 K, and || = 1.5 kW. Therefore,
|| = 0.75( - )
Similarly,
|
| = 
- 1
1.5/0.75*( - 298.15) = (/298.15
Further simplification,
= 49.4°C
