Answer:
B
Explanation:
Under process costing, costs assigned to goods sold are transferred to the Cost of Goods Sold account from the Finished goods inventory account
The simple reason can be that Earlier than they are transferred to cost of goods sold account and being sold, they are finished goods right before it. So, they are actually transferred from finished goods inventory account only.
Answer:
(a.) 4z
(b.) 4w
Explanation:
From the equation y=4zcos(8πwt), where z and w are positive constants.
Comparing this equation to the equation of a wave y = Acos(Wt), where A is the amplitude (largest distance from equilibrium) and W is the angular frequency (W=2πf)
(a.) Comparing our wave equation with the given equation, we see that A = 4z in this case (furthest distance of the mass from equilibrium)
(b.) Comparing similarly we can see from our given equation that angular frequency W =8πw we also know that W = 2πf from our wave equation, therefore 2πf = 8πw
Solving for f we have f = 8πw÷2π
f = 4w (Proves our second answer because the frequency is the number of oscillations completed per second)
Answer:
Electrons.
Explanation:
Electricity was discovered before the discovery of electrons by J.J Thompson in 1896. Before the electron, it was thought that it is the positive ions that move through the wire and carry current—that's why today the conventional current represents the flow of positive charges.
After J.J Thompson's discovery of the electrons, it was realized that it is the electrons that actually carry the current through the conductor. But changing the direction of the conventional current didn't seem appropriate, and that's why the convention continues to be used to this day—reminding us that once it were the positive ions that were thought to carry the current.
