Which one of the following parenting factors is associated with improved IQ scores in children? A. Strict discipline
B. Lenient discipline and fewer rules
C. A stable home and varied activities
D. Early instruction in reading

Answers

Answer 1
Answer:

Answer: Option (C) is the correct answer.

Explanation:

The term IQ stands form intelligent quotient. When a child is provided with stable home environment in which there are less or rare conflicts, happy environment, understanding between individuals etc will lead to a stable growth of child.

Also, varied activities will help child to learn quickly and develop various skills.

Thus, a stable home and varied activities is the one parenting factor which is associated with improved IQ scores in children.

Answer 2
Answer: The correct answer is C. A stable home and varied activities.

Hope this helps! xoxo

How many nitrogen atoms are in one molecule of (NH4)2SO4?

Answers

15 nitrogen atoms are in one molecule

Final answer:

In one molecule of (NH4)2SO4 or ammonium sulfate, there are two nitrogen atoms.

Explanation:

The molecule (NH4)2SO4 is known as ammonium sulfate. This molecule is composed of two ammonium ions (NH4) and one sulfate ion (SO4). The ammonium ion consists of one nitrogen atom (N) and four hydrogen atoms (H). Because the formula indicates there are two ammonium ions (as shown by the subscript '2'), this means the overall molecule of ammonium sulfate contains two nitrogen atoms.

what variables affect the acceleration of an object and in what matter do they affect the acceleration?

Answers


The variables that affect the acceleration of an object are

-- the object's mass
and
-- the net force acting on the object.

            Acceleration = (net force) divided by (mass) .

The more mass an object has, the less acceleration it will have
in response to the same net force.

The more net force acts on an object, the more acceleration
the object will have.

When we say that an object wants to maintain its state of motion, we’re talking about inertia. Which term determines the quantity of inertia for an object?

Answers

Inertia is determined by the mass of the object. greater the mass an object has, greater will be its inertia. smaller the mass an object has, smaller will be its inertia. Greater mass enables an object to resist change in its state of motion or rest while on the other hand smaller mass object can be easily made to change its state of motion or rest.

and object has mass, so if moving, has a momentum value.

Answer:

stupid question

Explanation:

A child lifts a 5.0-newton toy to a height of 0.50 meters. How much work is done on the toy?

Answers

you can use the formula

Work = force x distance

therefore, 

W= (5.0)(.50)
W = 2.5 joules

hope this helps :)
Work done=mgh
W=force*height
W=5N*0.50mts
W=2.5joule

How does the concentration of a hydrogen ion affect the ph levels of a substance?

Answers

Acidic and basic are two extremes that describe chemicals, just like hot and cold are two extremes that describe temperature. Mixing acids and bases can cancel out their extreme effects, much like mixing hot and cold water can even out the water temperature. A substance that is neither acidic nor basic is neutral. 

The character of acidic, basic and neutral is defined by the concentration of hydrogen ions [H+](mol/L). A solution with a concentration of hydrogen ions higher than 10-7mol/L is acidic, and a solution with a lower concentration is alkaline (another way to say basic). Using the formula, pH=-log[H+], a pH of 7 is neutral, a pH less than 7 is acidic, and a pH greater than 7 is basic. As one can see from this formula, ten times a given concentration of hydrogen ions means one unit lower in terms of pH value (higher acidity), and vice versa. 

Pure water is neutral, with a pH of 7.0. When chemicals are mixed with water, the mixture can become either acidic or basic. Vinegar and lemon juice are acidic substances, while laundry detergents and ammonia are basic. 

Chemicals that are very basic or very acidic are called "reactive." These chemicals can cause severe burns. Automobile battery acid is an acidic chemical that is reactive. Automobile batteries contain a stronger form of some of the same acid that is in acid rain. Household drain cleaners often contain lye, a very alkaline chemical that is reactive.
