Answer: True
Explanation: The amount of natural gas supplied in the residential area has lesser cost as compared with the electric power industry. The cost is lesser for the natural gas because it is abundantly available resource in the environment and electricity is generated by several methods and thus supplied so there is more effort and resources required and this costs more .Therefore, natural gas is cheaper as compared with electric power .
Answer:
Is it part of a computer?
Explanation:
Answer:
43248 newtons.
Explanation:
Force = mass x accelerations and units of force are newtons which are given in the question.
here mass = 125 of air and 2.2 of fuel, total = 125+2.2=127.5kg/s and the velocity of the exhaust is 340m/s.
force = 340m/s * 127.5kg/s = 43248 newtons technically this is wrong (observe units) but i will expalin how i have taken acceleration as a velocity here and mass/unit time as simply mass.
see force is mass times acceleration or deceleration, here our velocity is not changing therefore it is constant 340m/s but if it were to change and become 0 in one second then there would be -340m/s^2 (note the units ) of deceleration and there would be force associated with it and that force is what i have calculated here. similarly there would be mass in flow rate of mass per second, which is also in that one second of time.
let's calculate error.
error = (actual-calculated)/actual. = (43248-60000)/43248= -38.734% less is ofcourse greater than 2%.
So the load cell is not reading correct to within 2% and it should read 43248newtons.
Volume=Hh(b1+b2)/2. b1 and b2 are the base of the trapezoid
