Answer:
THANKS I NEEDED THIS SOOO MUCH!!!$
Answer:
A. 0.0450
B. 4
C. 0.25
D. 37.68
E. 6Hz
F. -0.523
G. 1.5m/s
H. vy = ∂y/∂t = 0.045(-37.68) cos (25.12x - 37.68t - 0.523)
I. -1.67m/s.
Explanation:
Given the equation:
y(x,t) = 0.0450 sin(25.12x - 37.68t-0.523)
Standard wave equation:
y(x, t)=Asin(kx−ωt+ϕ)
a.) Amplitude = 0.0450
b.) Wave number = 1/ λ
λ=2π/k
From the equation k = 25.12
Wavelength(λ ) = 2π/25.12 = 0.25
Wave number (1/0.25) = 4
c.) Wavelength(λ ) = 2π/25.12 = 0.25
d.) Angular frequency(ω)
ωt = 37.68t
ω = 37.68
E.) Frequency (f)
ω = 2πf
f = ω/2π
f = 37.68/6.28
f = 6Hz
f.) Phase angle(ϕ) = -0.523
g.) Wave propagation speed :
ω/k=37.68/25.12=1.5m/s
h.) vy = ∂y/∂t = 0.045(-37.68) cos (25.12x - 37.68t - 0.523)
(i) vy(3.5m, 21s) = 0.045(-37.68) cos (25.12*3.5-37.68*21-0.523) = -1.67m/s.
Answer:
The correct answer to the given question is option D) Any or all of the above.
Explanation:
A posting error is a type of error which is related to ledger and would include the errors like -
Posting wrong amount on the right side of account
Posting right amount on the wrong side of right account
Posting an amount twice and posting omission
Posting wrong amount to wrong side of right account
Posting correct amount on wrong account on right side
So by knowing all the given above points, it is quite clear that the correct option is D.
Answer:
The answer is "Actual products".
Explanation:
The key purpose of this research is to better analyze the concepts, which is done to establish customer buying expectations and perceptions of the item. The key point is to assess the consumers ' initial response to the product idea.
- This concept testing is also known as a creation, it is an advantage, which can be conveyed to the user to test their reactions.
- In conceptual testing, it is a quality check between the design definition and the actual production of the product.
