Images help tell a story where describing with words is either too lengthy, or practically impossible. For instance, you could have a map of a location and various arrows and other markings to describe movements of troops during a battle of the civil war. This is one example of many that you could have as an image on a website. Describing the troop movements with words only may be really difficult to do. Plus many people are visually oriented learners, so they benefit with images every now and then. Of course, it's best not to overdo things and overload the site with too many images. A nice balance is needed.
Answer:
t= 8.7*10⁻⁴ sec.
Explanation:
If the signal were able to traverse this distance at an infinite speed, the propagation delay would be zero.
As this is not possible, (the maximum speed of interactions in the universe is equal to the speed of light), there will be a finite propagation delay.
Assuming that the signal propagates at a constant speed, which is equal to 2.3*10⁸ m/s (due to the characteristics of the cable, it is not the same as if it were propagating in vaccum, at 3.0*10⁸ m/s), the time taken to the signal to traverse the 200 km, which is equal to the propagation delay, can be found applying the average velocity definition:
If we choose x₀ = 0 and t₀ =0, and replace v= 2.3*10⁸ m/s, and xf=2*10⁵ m, we can solve for t:
⇒ t = 8.7*10⁻⁴ sec.
Answer:
Intel produces a series of unlocked CPU's that can be overclocked. These CPUs are from the "K" or "X" series. Example: Intel Core i9-9900K, Intel Core i9-10940X.
These are the few things that are to be kept in mind while overclocking:
-Motherboard: Motherboard should support overclocking. Example: Intel Z series, most AMD motherboards.
-Cooler: Boosting the clock speed increases the temperature. The cooler has to be upgraded to keep the temperatures low. Example: Water-cooled. Also, the heat sink has to be checked if it's working properly.
-Be ready to test your system in BIOS. Make sure the temperature, voltage, memory speed is stable for the set clock speed.
Explanation:
Answer:
scanf() function is used to get a input from keyboard.This function is in the stdio.h library.To use this function we must include the stdio.h library first in the code. Then only we can use the scanf() function in any code.printf() function is used to print anything .this function is from stdio.h library.
Code to read voltage drop across the register.
#include <stdio.h>
// main function
int main(void) {
// variable
double vr1;
printf("Enter voltage drop:");
// read voltage drop from user
scanf("%lf",&vr1);
// print voltage drop
printf("voltage drop is:%0.2lf",vr1);
return 0;
}
Output:
Enter voltage drop:200.4
voltage drop is:200.40
Answer:
item = "quesadilla"
meat = "steak"
queso = False
guacamole = False
double_meat = False
base_price = 4.5
if item == "quesadilla":
base_price = 4.0
elif item == "burrito":
base_price = 5.0
if meat == "steak" or meat == "pork":
base_price += 0.50
if meat == "steak" and double_meat:
base_price += 1.50
elif meat == "pork" and double_meat:
base_price += 1.50
elif double_meat:
base_price += 1.0
if guacamole:
base_price += 1.0
if queso and item != "nachos":
base_price += 1.0
print(base_price)
Explanation:
- Use a conditional statement to check if meat is steak or pork then add 0.50 to base_price
.
- Check if the meat is steak or pork, then double_meat adds 1.50 or 1.0 otherwise
.
-
Check if meat is steak and its double_meat
, then add 1.50 and if its for guacamole, then add 1.00 to base_price
. If queso is there and item is not nachos, add 1.00 to base_price
.
- Finally when item is nachos, no need to add any money to base_price
.
