Greece
Poland
i will mark u brainliest mf

Answers

Answer 1
China in 1100 AD, if I am wrong I'm sorry.
Answer 2

Answer:

Greece

Explanation:

It is believed that the reaction principle, the physical law of rocket motion, was first demonstrated about 360 B.C. by a Greek named Archytas. Far from demonstrating the reaction principle in a weapon, Archytas simply filled a hollow clay pigeon with water. He then suspended the clay pigeon by string over a fire. The heating of the water produced steam, and the clay pigeon could move under its own power as steam escaped through strategically placed holes. Archytas could hardly have imagined that the same basic principle would one day carry men to the Moon.

write 3 things that can't be done without technology. write your opinion?

Answers

Answer: Call a theater to get movie times, Use a phone book to find a company to do work around your house, and Park your used car on the street with a sign that says it’s for sale.

Explanation: my opinion is that it's fine to do each of those things without technology. Because technology is supposed to help the limited capacity of the human brain and improve things that make every day life quicker, easier, leaves more time to do something else.

Answer:

1) Filming, depending on the camera it is still technology that everyone uses on a daily bases with no hesitation for use.

2) Vehicles, I'm not sure if they are a type of technology but for this case lets just say they are. With vehicles we can get to places much faster then walking or taking a carriage.

3)Records, in this case music. Without records or anything of the sort we wouldn't exactly be able to listen to our favorite music at all times.

1.Menciona tres factores o variables que consideras influirán en el oscurecimiento del alimento cortado o pelado expuesto a la intemperie

Answers

La respuesta correcta para esta pregunta abierta es la siguiente.

A pesar de que no se incluyen opciones o incisos para responder a la pregunta, podemos comentar lo siguiente.

Los tres factores o variables que considero influyen en el oscurecimiento del alimento cortado o pelado expuesto a la intemperie son los siguientes.

1.- La exposición al elemento "oxígeno" cuando están a la intemperie.

2.- La temperatura del medio ambiente que afecta directamente al alimento.

3.- Los minerales y los metales que constituyen al alimento cuando tienen contacto con el medio ambiente.

En estos momentos, las sustancias que componen al alimento comienzan a tener reacciones químicas y se empiezan a oxidar cuando permanecen abiertas a temperaturas ambiente.

Es por eso que los expertos recomiendan que una vez abierta la comida -la fruta, la verdura- tiene que refrigerarse lo más pronto posible para poderse conservar un poco más de tiempo.

Using cell references enter a formula in B6 to calculate monthly payments for the loan described in this worksheet Omit the optional arguement use a negative value for pv

Answers

Answer:

= PMT(B4/B2, B2 * B3, B1)

Explanation:

The syntax to use is:

= PMT(Rate,NPER, PV)

To answer this question, the following assumptions will be made.

B1 = Present Value i.e. PV

B2 = Number of Payment Period i.e n

B3 = Duration (in years)

B4 = Rate

So, the formula to enter in B6 is:

= PMT(B4/B2, B2 * B3, B1)

The above formula will return the monthly payment in cell B6

Write a program in Java that asks the user to enter four weighted assessment grades, calculate the average, then display the average with the message: "Student Pass" if the average is greater than or equal 60 or the message "Student Fail" otherwise. The details of the assessments and weights are as follow: Homeworks: 20% Labs: 15% Midterm: 25% Final: 40%

Answers

Answer:

Explanation:

In order to calculate the weighted average, the grade itself is multiplied by the percentage of the category and then these values are summed. This sum is then divided by the total percentage of the portfolio.

import java.util.Scanner;

class Main {

   public static void main(String[] args) {

       double sumOfWeights = 100;

       

       

       Scanner in = new Scanner(System.in);

       

       System.out.println("Please Enter Homework Grade: ");

       double homework = in.nextDouble() * 20;

       System.out.println("Please Enter Labs Grade: ");

       double labs = in.nextDouble() * 15;

       System.out.println("Please Enter Midterm Grade: ");

       double midterm = in.nextDouble() * 25;

       System.out.println("Please Enter Final Grade: ");

       double finals = in.nextDouble() * 40;

       

       double average = (homework + labs + midterm + finals) / sumOfWeights;

       System.out.println("The Average of these Weighted Grades is " + average);

A video streaming website uses 32-bit integers to count the number of times each video is played. in anticipation of some videos being played more times than can be represented with 32 bits, the website is planning to change to 64-bit integers for the counter. which of the following best describes the result of using 64-bit integers instead of 32-bit integers? a. 2 times as many values can be represented. 32 times as many values can be represented. 2^32 times as many values can be represented. 32^2 times as many values can be represented. I know the answer is 2^32 but can someone explain it to me?

Answers

Answer:

2³² times as many values that can be represented

Explanation:

A 64 bit register can hold 2⁶⁴ different values, while a 32 bit register can hold 2³² different addresses

Therefore, a 64 bit can represent 2⁶⁴ ÷ 2³² = 2³² times as many values as can be represented by 32-bit

Therefore, the 64 bit can represent 2³² times as many values that can be represented by a 32 bit integer

The scale needs to be calibrated to ensure accuracy.

Answers

Answer: Use data from the previous steps because they show better results

Explanation:

A scientific bias occurs when there's a deviation between the observations of a researcher and the accurate representation of data and results.

In this case, the use of data from the previous steps because they show better results will bring about a data bias as it'll lead to inaccuracies of the data being represented.
