I believe the answer is the second one
Answer:
16
Step-by-step explanation:
50-2= 48
48 divide by 2 is 16
Answer B
There are 16 oz in a pound. 16(2)=32 and there are 4 oz leftover.
Answer:
The correct answer is b.
Step-by-step explanation:
The wave equation is given generally as:
c(x, t) = Acos(kx - wt)
Where A = amplitude
k = wave number
w = angular frequency.
x = horizontal distance moves by the wave.
t = time
The options show to us that the wave depends only on t and not (x, t).
Hence, the wave equation becomes:
c(t) = Acos(wt)
Given that:
A = 5 V
f = 1 * 10⁶ Hz
Angular Frequency, w, is given as:
w = 2πf
w = 2 * π * 1 * 10⁶ Hz
w = 2π(1 * 10⁶)
The wave equation becomes:
c(t) = 5cos(2*π*1*10⁶)
The correct answer is b.
Step-by-step explanation:
Since we have given that
By using logarithmic on both sides we get,
(∵ 
)
Now, differentiating on both sides ,we get,
