Answer:

the force of gravity (Fgrav) and the normal force (Fnorm).

Explanation:

Neglecting friction and air resistance, a roller coaster car will experience two forces:the force of gravity (Fgrav) and the normal force (Fnorm). The normal force is directed in a direction perpendicular to the track and the gravitational force is always directed downwards.

Answer:

Gravity force (g-force) and normal force

Explanation:

Neglecting friction and air resistance, a roller coaster will experience two forces which are the force of gravity (Fgrav) and the normal force (Fnorm).

Question 5 of 10

Angelina_Jolie [31]

The cubic inch space that is required inside a box for 4 #6 XHHN current carrying conductors will be D. 8 cubic inches.

<h3>What is a conductor?</h3>

It should be noted that a conductor simply means a substance or material that simply allows electricity to pass through it.

From the information given, the cubic inch space that is required inside a box for 4 #6 XHHN current carrying conductors is yo be computed.

This will be:

= (4 × 6)/3

= 24/3

= 8

In conclusion, the cubic inch space that is required inside a box for 4 #6 XHHN current carrying conductors will be 8 cubic inches.

A 2-kW pump is used to pump kerosene ( rho = 0. 820 kg/L) from a tank on the ground to a tank at a higher elevation. Both tanks

Alborosie

The maximum volume flow rate of kerosene is 8.3 L/s

<h3>What is the maximum volume flow rate?</h3>

In fluid dynamics, the maximum volume flow rate (Q) is the volume or amount of fluid flowing via a required cross-sectional area per unit time.

In fluid mechanics, using the following relation, we can determine the maximum volume flow rate of kerosene.

Power = mass flow rate(m) × specific work(w) --- (1)
Specific work = acceleration due to gravity (g) × head (h) ---- (2)
Mass flow rate (m) = density (ρ) × volume flow rate (Q) --- (3)

By combining the three equations together, we have:

The power gained through the fluid pump to be:

P = ρ × Q × g × h

Making Q the subject, we have:

$\mathbf{Q = \dfrac{P}{\rho \times g \times h}}$

where:

P = 2 kW = 2000 W
ρ = 0.820 kg/L
g = 9.8 m/s
h = 30 m

$\mathbf{Q = \dfrac{2000 \ W }{820 \ kg/m^3 \times 9.8 m/s \times 30 \ m}}$

Q = 0.008296 m³/s

Q ≅ 8.3 L/s

Fix the code so the program will run correctly for MAXCHEESE values of 0 to 20 (inclusive). Note that the value of MAXCHEESE is

GarryVolchara [31]

Answer:

Code fixed below using Java

Explanation:

<u>Error.java </u>

import java.util.Random;

public class Error {

public static void main(String[] args) {

final int MAXCHEESE = 10;

String[] names = new String[MAXCHEESE];

double[] prices = new double[MAXCHEESE];

double[] amounts = new double[MAXCHEESE];

// Three Special Cheeses

names[0] = "Humboldt Fog";

prices[0] = 25.00;

names[1] = "Red Hawk";

prices[1] = 40.50;

names[2] = "Teleme";

prices[2] = 17.25;

System.out.println("We sell " + MAXCHEESE + " kind of Cheese:");

System.out.println(names[0] + ": $" + prices[0] + " per pound");

System.out.println(names[1] + ": $" + prices[1] + " per pound");

System.out.println(names[2] + ": $" + prices[2] + " per pound");

Random ranGen = new Random(100);

// error at initialising i

// i should be from 0 to MAXCHEESE value

for (int i = 0; i < MAXCHEESE; i++) {

names[i] = "Cheese Type " + (char) ('A' + i);

prices[i] = ranGen.nextInt(1000) / 100.0;

amounts[i] = 0;

System.out.println(names[i] + ": $" + prices[i] + " per pound");

}
