Answer:
Explanation:
The speed of hare = .15 x 25 = 3.75 m /s . Let tortoise took t second to complete the race .
Distance traveled by it = .15 t
Distance traveled by hare = .15 t - .35 m
Time taken by hare to complete this distance
= t - 5 x 60 s
Speed of hare
= Distance / time
( .15t-.35 ) / t - 300 , so
t = 312.40
= 5 minutes 12.4 seconds
Distance of race
312.4 x speed of tortoise
= 312.4 x .15
= 46.85 m
He had their masses and reactivity. I hope this helps.
Answer: shorter/longer developing time.
Explanation:
Ideally, the time to process a radiographic image in the developer is 680 F for 5 minutes. But films may be removed from the fixing solution after 5 minutes (and fixed back) for viewing, only at emergencies like if the temperature of the developing solution is slightly above normal.
If the temperature of the developing solution is slightly above normal, the radiographic images of the required density may be produced by permitting a shorter/longer developing time.
Explanation:
The table is level and there are no other forces on the book, so the normal force is equal to the weight.
N = mg
N = (2.3 kg) (9.8 m/s²)
N = 22.5 N
