we know that
the speed is equal to
The slope of the line on the graph is equal to the speed of the car
so
during the segment B the slope of the line is equal to zero
that means
the speed of the car is zero
therefore
<u>the answer is the option B</u>
The car has come to a stop and has zero velocity
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:
309 m
Explanation:
time apart = 0.8 s
speed of sound in air = 343 m/s
speed of sound in concrete = 3000 m/s
lets assume it time it takes to travel trough concrete = T
the time it takes to travel through air = T + 0.8 since they are 0.8 s apart
the distance traveled by both waves is the same, so we can equate the distance for both waves
distance = speed x time
- for concrete, distance = 3000 x T
- for air, distance = 343 x (T + 0.8)
now equating the two distance together we have
3000 x T = 343 x (T + 0.8)
3000T = 343T + 274.4
3000T - 343T = 274.4
T = 0.103 s
recall that distance = 3000 x T = 3000 x 0.103 = 309 m
6.6 miles I think hope this is the right answer.
