We can import Scanner from Java.utils.Scanner to pull in text entered in the console.
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
String password = "";
do {
System.out.print("Enter your password: ");
password = sc.nextLine();
if(!password.equals("pals") {
System.out.println(\nIncorrect Password. Try again.");
}
} while(!password.equals("pals");
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:
For Simple AAA. title games you can get a gtx 1050 ti which can run games decent about 60 fps on med to low settings i my self am running a r7 370 and i play FiveM at 40 fps or gta5 at 60 csgo at 120 fps if you want to go higher go with the best graphics and fps go with something cheap but extreme a RTX 2070 or 2080 and with ram it help the computer run smoother basically imagin what a plate is ram so more plates you have the more food you can store in it untill someone (the computer) uses it all its a quick storage for limited time the more the better usually for gaming a 16gb should be enough
Explanation:
Device management is the process of managing the devices in your computer.
In your computer you have the so-called device manager, in which all the drivers of your devices are installed. Device Manager allows you to monitor and manage each of its devices. You can also uninstall and update your devices in device manager. And the process of doing it is called device management. It is very simple to do this kind of stuffs as long you are familiar with your devices like mouse, printer, keyboard, etc.
Answer:
The code to calculate the area of a circle is:
from math import pi
def circleArea(radius):
if radius > 0:
return pi * (radius ** 2)
else:
return None
if __name__ == '__main__':
radius = 5
print("Radius: {} Area: {}".format(radius,circleArea(radius)))
Explanation:
A detailed explanation of each line of code is given below.
#Define the number pi used to calculate the area
from math import pi
#We define a function that calculates the area of a circle
def circleArea(radius):
#Check if the radius is valid ( radius > 0) since there aren´t negative radius
if radius > 0:
#Compute the area formula for a circle 
return pi * (radius ** 2)
else:
#Return None if the radius is invalid
return None
#Run the function we´ve defined
if __name__ == '__main__':
#Define a radius
radius = 5
#Call the function and parse the radius through it, then print the result
print("Radius: {} Area: {}".format(radius,circleArea(radius)))
