Answer:

C. A rubber rod and a glass rod charged this way have opposite charges on them.

Explanation:

When a rubber rod is rubbed against cat fur, it acquires a negative charge, it becomes negatively charged.

When you then try to bring two rubber rod's together, they repel because like charges repel.

Meanwhile, when you rub a glass rod against silk, it loses electrons to the silk material and becomes positively charged.

When you bring two positively charged glass rod's together, they repel, because like charges repel.

However, when you bring the rubber rod and a glass rod together, the attract each other because unlike/opposite charges attract.

What was the total weight (lbf) of chocolate in the vat? the specific gravity of chocolate is approximately 1.24?
8_murik_8 [283]
I believe this question is missing some information, but I'll just tell you how to solve it and you can apply using the information you have.

First, we have the specific gravity which is the ratio between the density of the substance to the density of water at 4 degrees celcius (1000 kg/m^3)
specific gravity of milk = density of milk/density of water
1.24 = density of milk/1000
density of milk = 1240 kg/m^3

Then we have:
density = mass/volume
I believe the question should have any information regarding the volume.
You will use this information to calculate the mass of milk in kg.

Then, you will change the kg to pound (lb) using cross multiplication. 
(1 kg = 2.2 lb).

The last step is to calculate the weight in lbf. To do this, you will simply multiply the mass (in lb) by the gravity (9.8 m/s^2)

14) Modify the method that calculates the sum of the integers between 1 and N. Have the new version match the following recursiv
Setler [38]

Explanation:

Let solve the program using Java programming language

Method: method means group of statements to perform some operation.

             let call the method sum.

Parameters: list of variables that are use in the method for declaration.

<u>The code</u>

public int sum (int number)

int answer;

if (number == 1)

answer = number;

else

{

int half = number/2;

int span = number - half;

answer = sum(half) + sum(span) + (half * span);

}

answer result;

}

Firstly we defined the method called sum(), the method takes only one parameter which is number and return the answer(sum of  the integers 1 and N).

if the number is equal to 1, so it will return the number and if the number is not equal to 1 it will divide the number by 2 and get the span(span used to shift upper range).And result will add sum of half, sum of span and product of half span.

A ____fault forms as a result of horizontal compression.
kirill [66]

Answer:
