Answer: Separately derived system
Explanation: A separately derived system is used to describe a premise wiring system whose power is derived from a source of electrical energy such as transformer, solar photovoltaic cell or generator. A separately derived system has no direct connection to any conductor from another system or doesn't generate it's power from any direct connection to a conductor from another system or source except those from established from bonding or grounding connections. Separately derived systems usually generate it's power on it's own.
F = force applied to hold the weight of the bowling ball = weight of the bowling ball = 75 N
d = distance through which the bowling ball is moved horizontally = 10 meter
θ = angle between the force in vertically upward direction and displacement in horizontal direction = 90
W = work done on the bowling ball
work done on the bowling ball is given as
W = F d Cosθ
inserting the values
W = (75) (10) Cos90
W = (75) (10) (0)
W = 0 J
Answer:B
Explanation:
For work to be done, the object must move some distance as a result of a force
To solve the problem it is necessary to apply the concepts related to Byle's Law and Avogadro's Law.
The ideal gas equation would help us find the final solution to the problem, defined by
![PV = nRT](https://tex.z-dn.net/?f=PV%20%3D%20nRT)
Where,
T= Temperature of the gas
R = Universal as constant
n = number of moles
V = Volume
P = Pressure
For our case we have that the mass of Zn is 2.2g in moles would be
[/tex]
![Zn = 0.0338](https://tex.z-dn.net/?f=Zn%20%3D%200.0338)
We know that 1 mole of hydrogen gas is proceed by 1 mole of zinc and the result is
, then Hydrogen can produce the same quantity,
![H_2 = 0.0338](https://tex.z-dn.net/?f=H_2%20%3D%200.0338)
Applying the previous equation we have that
![V= \frac{nRT}{P}](https://tex.z-dn.net/?f=V%3D%20%5Cfrac%7BnRT%7D%7BP%7D)
![V = \frac{0.0338*0.08206*293.15}{0.98}](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%7B0.0338%2A0.08206%2A293.15%7D%7B0.98%7D)
![V = 0.829L](https://tex.z-dn.net/?f=V%20%3D%200.829L)
Therefore the volume of hydrogen gas is collected is 0.829L
