Answer:
n = 18 cycles
Step-by-step explanation:
To know how many times does the current oscillates in the given time, you take into account that the number of oscillation can be calculated by using the following expression:
(1)
f: frequency of the oscillation of the current
t: time = 0.30s
The frequency is the number of cycles per second, that is, f = 60 cycles/s
You replace the values of f and t in the equation (1):
In 0.30s the current oscillates 18 times
Answer:
(600 miles) / (3 hours) = 200 miles/hour
= 321.8 km/h
18/6
18= the number of trucks
6= the number of hours
18/6= 3 trucks per hour
<u>Answer:</u>
<u>Step-by-step explanation:</u>
To find the solution to the equation, we have to rearrange the equation to make the subject:
⇒ [Subtracting 2 from both sides]
⇒
⇒ [Subtracting from each side]
⇒
⇒ [Diving both sides by 213]
⇒
Answer:
51/40
Step-by-step explanation:
2/5+7/8
(2*8/5*8)+(7*5/5*8)
16/40+35/40
=>51/40
