Answer:


Explanation:
Given
--- Initial altitude
-- Altitude after 16.5 seconds
--- Acceleration (It is negative because it is an upward movement i.e. against gravity)
Solving (a): Final Speed of the rocket
To do this, we make use of:

The final altitude after 16.5 seconds is represented as:

Substitute the following values:
and 
So, we have:



Collect Like Terms


Make u the subject



Solving (b): The maximum height attained
First, we calculate the time taken to attain the maximum height.
Using:

At the maximum height:
--- The final velocity

So, we have:

Collect Like Terms

Make t the subject


The maximum height is then calculated as:

This gives:





Hence, the maximum height is 1141.07ft
The maximum height that the water can rise above the jet is: 35 meters.
<h3>Maximum height that the water can rise above the jet</h3>
Given:
P = 350 kPa = 350000 Pa
We would use pressure(p) formula to determine the maximum height that the water can rises above the jet by solving for h (height).
Using this formula
Pressure(P) = P₀ + ρgh
Where;
P₀ represent Pressure at the fluid's surface
ρ represent Density of the fluid = 1000 kg/m³
g represent acceleration due to gravity = 10 m/s².
h represent height
Solving for h (height)
350000 = 0 + (1000 × 10 ×h)
350000 = 10000h
Divide both side by 10000h
h = 350000/10000
h = 35 meters
Therefore the maximum height that the water can rise above the jet is: 35 meters.

Answer:
import java.util.Scanner;
public class AssigningNumberToVariable {
public static void main (String [] args) {
int numPeople;
int numPeople_inc;
numPeople = 10;
/* solution */
numPeople_inc=numPeople+5;
System.out.print("There are ");
System.out.print(numPeople_inc);
System.out.println(" people.");
}
}
Explanation:
1. Declare a new variable called: numPeople_inc
2. Add 5 each time: numPeople_inc=numPeople+5;
3. Print the answer: numPeople_inc=numPeople+5;
Optional, just write the line in the place where says: " your solutions goes here":
numPeople = numPeople+5;
Answer:
your answer for this question would be D
Explanation:
the purpose of structural components such as frames, bearings, and mounts is to transfer input energy from the power source throughout the machine.
the structure such as bearings, frames, and mounts support input or in other words signals (energy) components within the machine can be more functional
