Answer:
17.0 m s^-1
Explanation:
This question can be answered using suvat equations: (I'm assuming you know what these are)
s = 34.0 m
u = 0
v = ?
a = N/A
t = 4.00s
The only suvat equation that doesn't contain "a" is s = (u+v/2)t.
Make "v" the subject so v = 2s/t.
v = (2 x 34.0)/4.00 = 17 m/s
Knowing the distance may only give you the relative locations between two points, but not the exact location. So, the answer to his question is no. Knowing the distance does not give enough information. If perhaps the coordinates of both points were given, then that would be considered enough information.
Answer:
433.15K
Explanation:
(320°F − 32) × 5/9 + 273.15 = 433.15K
Answer:
a) 3170 kw
b) 377 km^2
Explanation:
Estimate of electric power
a) Given :
Average power consumption for a family of 3 = 108.4 * 106 BTU per year = 0.0317 kw = 31.7 watts
<u>The power requirement for a city of 300000 people </u>
= 31.7 watts * 100000 = 3170000 watts = 3170 kw
b) Given :
Average solar panel insulation = 8.4 W /m^2
<u>Estimate the area of silicon solar cells required to satisfy community power requirement</u>
= (1 * 3170) * (1000/8.4 )
= 377.380 * 10^3 m2 = 377 km^2
