.2 (simplified from 0.20)
2/10 (simplified from 20/100)
Answer:
4 x (1 x 4) = 16
Step-by-step explanation:
1 x 4 = 4
4 x 4 = 16
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.
The answer to your question is about 9 times so ya that your answer about 27 times
Answer:
As there is one math problem over there.
Lets see the question first:
It says that "A hair dryer is rated 
,if you use the dryer for 
.How much electric energy do you use ?"
Final answer = Electic energy 
Step-by-step explanation:
Electrical Energy 
.
The total amount of electrical energy used depends on the total power used by the electrical device and the total time they are used for.
So we have been given the power of the hair dryer 
Now the time it has been use for 
To calculate electric energy we will multiply both the terms.
Electric energy 
So electric energy used for the hairdryer is =
