The aliased frequency that is due to small sampling frequency is 675 Hz.
The proposed sampling frequency is 2f = 120
How to solve for the aliased frequencyThe signal frequency that is given in the question is 60Hz
The sampling frequency is 90Hz
a. Using Nyquist frequency,
fn = 0.5*90Hz = 45Hz
The aliased frequency = |n*fn - fs|
aliased frequency = |n*fn - fs|
We have n >= 1/Fs = 17ms
Then the aliased frequency is = 17 x 45 - 90
= 675 Hz
b) The Nyquist sampling theoremIn order to avoid aliasing the sampling frequency, this has to be at least two times the highest frequency.
Therefore Fs =
2xF = 120Hz

Steering and suspension question
Answer:
I would say only A
Explanation:
steering dampeners are applied to heavy-duty and off-road vehicles in order to help stabilize and balance out your steering in rough terrain. luxury cars won't have them because, well, they are cars, and cars are not used for off-roading. trucks and SUVs and sometimes vans are though, which makes sense more than just a random luxury car with dampeners just sitting there for no reason at all when heavy-duty vehicles need them more than the car.
What is the wavelength of a photon with an energy of 3. 38 x 10^-19 j
The photon has a wavelength of 588 nm
what is a wavelength?Wavelength is the distance between two points along the path of the wave.
it is usually represented by λ
Energy of a photon, E = ( h c ) / λ
where:
h is Planck's constant = 6.626 × 10 -34 Js
c is speed of light = 3.0 * 10^8 m/s
λ = ( h c ) / E
λ = ( ( 6.626 × 10 -34 ) * ( 3.0 * 10^8 ) ) / 3.38 * 10^-19
λ = 5.88 * 10^-7 m
λ = 588 * 10^-9 m = 588 nm
λ = 588 nm = 588 nanometers

In python
Write an expression that executes the loop body as long as the user enters a non-negative number.
Note: If the submitted code has an infinite loop, the system will stop running the code after a few seconds and report "Program end never reached." The system doesn't print the test case that caused the reported message.

Answer:
inputed = input("Choose some numbers, each separated with a space: ")
chosen = list(inputed)
chosen = chosen.remove(' ')
for value in chosen:
if '-' not in value:
