<h3>How to code?</h3>
- We connect with computers through coding, often understood as computer programming.
- Coding exists similar to writing a set of instructions because it instructs a machine what to do.
- You can instruct computers what to do or how to behave much more quickly by learning to write code.
class ICalculator {
int currentValue;
int add(int value) {
this.currentValue = currentValue + value;
return currentValue;
}
int sub(int value) {
this.currentValue = currentValue - value;
return currentValue;
}
int mul(int value) {
this.currentValue = currentValue * value;
return currentValue;
}
int div(int value) {
this.currentValue = currentValue / value;
return currentValue;
}
}
public class ICalculator2 extends ICalculator {
int negate() {
if (currentValue != 0)
this.currentValue = -currentValue;
return currentValue;
}
public static void main(String[] args) {
ICalculator2 ic = new ICalculator2();
ic.currentValue=5;
System.out.println(ic.add(2));
System.out.println(ic.sub(5));
System.out.println(ic.mul(3));
System.out.println(ic.div(3));
System.out.println(ic.negate());
}
}

Answer:
The maximum theoretical height that the pump can be placed above liquid level is 
Explanation:
To pump the water, we need to avoid cavitation. Cavitation is a phenomenon in which liquid experiences a phase transition into the vapour phase because pressure drops below the liquid's vapour pressure at that temperature. As a liquid is pumped upwards, it's pressure drops. to see why, let's look at Bernoulli's equation:
(
stands here for density, 
for height)
Now, we are assuming that there aren't friction losses here. If we assume further that the fluid is pumped out at a very small rate, the velocity term would be negligible, and we get:
This means that pressure drop is proportional to the suction lift's height.
We want the pressure drop to be small enough for the fluid's pressure to be always above vapour pressure, in the extreme the fluid's pressure will be almost equal to vapour pressure.
That means:
We insert that into our last equation and get:
And that is the absolute highest height that the pump could bear. This, assuming that there isn't friction on the suction pipe's walls, in reality the height might be much less, depending on the system's pipes and pump.
Answer:
The answer is not in the options. It is one-fourth.
Explanation:
As of 2017, it was recorded that nuclear power supplies 25% of electricity in Europe. That's 1/4 of the total electrical power supply.
Answer:
diesel engine
Explanation:
because diesel is stronger than petrol
The right components for gsm architecture that consists of the hardware or physical equipment such as digital signal processors, radio transceiver, display, battery, case and sim card is the Mobile station.
<h3>What are the 4 main components?</h3>
In GSM, a cell station includes 4 fundamental additives: Mobile termination (MT) - gives not unusualplace features consisting of: radio transmission and handover, speech encoding and decoding, blunders detection and correction, signaling and get right of entry to to the SIM. The IMEI code is connected to the MT.
Under the GSM framework, a cell tele cell smartphone is called a Mobile Station and is partitioned into wonderful additives: the Subscriber Identity Module (SIM) and the Mobile Equipment (ME).
