Answers:

1. a flowerpot sitting on a table

2. a leaf falling to the ground

3. The object's motion does NOT change.

4. change speed, direction, or both.

5. True

Explanations:

1. Net force is the sum of the forces acting upon an object. Often, this will be shown through diagrams with arrows pointing in certain directions and a certain amount of Newtons. A net force of zero means that the object is steady and stable in its motion (whether moving or staying still). With zero net force, an object will not change its speed nor direction. A football in the air is not the answer as gravity pulls it back down towards Earth, creating a change in both speed and direction. A cat running after a mouse is likely not the answer as well. Realistically, the cat and mouse will not continue at a constant speed in the exact same direction forever. Thus, a cat running after a mouse does not make sense. A flowerpot sitting on a table is not moving at all. It is not changing speed or direction; therefore, it does have a net force of zero. A speeding car is, well, speeding. Its speed is changing, just as the answer claims. Since a flowerpot sitting on a table is the only answer choice that has a net force of zero, it is the answer.

2. Unbalanced forces are unequal forces acting on one another from/in different directions. Unbalanced forces must be moving in some way. If they are not, then the forces are equal and balanced instead. They have to be changing direction and/or changing speed. A sweater sitting on a store shelf does not move at all; it never changes direction nor speed. It is an example of balanced, not unbalanced, forces. A letter sitting in a mailbox is just like the sweater - it doesn't change speed or direction, so it can't be an unbalanced force. A fence around a garden is planted firmly into the ground, thus unable to move in the first place. With no change, it is a balanced force, rather than an unbalanced one. A leaf falling to the ground is, according to the wording of the answer choice, currently falling. Gravity is acting upon it and pulling it towards the ground.  Since the leaf falling is in motion, or moving, there are unbalanced forces acting on it (specifically gravity pulling the leaf down). Therefore, the falling leaf is an instance of unbalanced forces.

3. Balanced forces are the opposite of unbalanced ones - they are equivalent forces that act in opposite directions in order to contradict/cancel each other. Since balanced forces are, well, balanced, neither one will overpower the other. No chance will occur as long as the forces remain balanced (ones). This lines up directly with Isaac Newton's first law of motion, which states that an object will continue to be at rest, or continue in a constant speed and direction, unless acting on by an external force. The external force will unbalance the forces, thus causing a change in speed and/or direction. Therefore, since balanced forces are forces that will not change speed nor direction, the answer should be that the object's motion does not change.

4. As stated earlier, unbalanced forces act in different directions with different amounts of power/Newtons. One must be/is more powerful than than rest; this is so that the unbalanced forces can be, you know, unbalanced. Unbalanced forces can cause a change in speed and a change in direction (it can be both or only one). Thanks to this information, we can conclude that the answer to this question is to change speed, direction, or both.

5. Balanced forces and a net force of zero are both included in the first law of motion. Both of these forces will continue at a consistent speed and direction until acted upon by another force. Since both of these terms have the same definition, it is reasonable to say that they are synonyms (which they are). Balanced forces and zero net force mean the same thing (and are the same thing). So, it is true that balanced forces is when the net force is zero.

The object has a net force of zero acting on it is  a flowerpot sitting on a table. A leaf falling to the ground  has unbalanced forces acting on it.The object's motion does not  change when the forces acting on it are balanced.When unbalanced forces act on an object that is in motion, the object can change speed, direction, or both.The statement a balanced forces is one in which the net force is zero is true.

Force is defined as a cause which is capable of changing the motion of an object. It can cause an object which has mass to change it's velocity. It is also simply a push or a pull . It has both magnitude as well as direction.Hence, it is a vector quantity.

It has SI units of Newton and is represented by'F'.Newton's second law states that force which acts on an object is equal to momentum which changes with time. If mass of object is constant, acceleration is directly proportional to net force acting on an object.

The concepts which related to force are thrust and torque .Thrust increases the velocity of an object and torque produces change in rotational speed of an object.

Explanation:

Concentration of NaOH will you place into the leaf jar to absorb the carbon dioxide at 0.75 M concentration.

Concentration is calculated by dividing a constituent's abundance by the mixture's total volume. Mass concentration, molar concentration, number concentration, and volume concentration are four different categories of mathematical description.

The amount of solute that has dissolved in a specific amount of solvent or solution is measured as solution concentration. A concentrated solution is one that has a significant amount of dissolved solute in it. A diluted solution is one that has a little amount of dissolved solute in it.

Concentration is the ratio of the volume of the solution ( V ) to the mass of the solute ( m ) that is dissolved in it. C = m / V. Molality, mole fraction, and molarity are the three methods for calculating the concentration of a solution.

Molarity, molality, mass percentage, parts per thousand, parts per million, and parts per billion are examples of quantitative units of concentration.

Thus, option C is correct.

Answer:

Option B

Explanation:

Remember that the products are on the right side of a chemical equation while the reactant is on the left.

In this case we have...

C2H6 + O2 ⇒ CO2 + H2O

Since C2H6 and O2 are on the left side that would mean they're the reactants, while CO2 + H2O are the products. Which means your answer is option B or "C2H6 + O2 are the reactants, CO2 + H2O are the products."

Explanation:

Answer:

A. Turn the volume up for more energy.

Explanation:

The reason why this is the correct answer is because the louder the music gets the more energy it puts out therefore the answer is option A.

The students increase the amplitude of the sound waves of the music turn the volume up to create more energy. Hence option A is correct.

Energy is defined as a quantitative quality that is conveyed to a person or a physical system and is discernible in the way work is done as well as in the way heat and light are produced. A conserved quantity is energy. According to the law of conservation of energy, energy can change its form but cannot be created or destroyed.

Sound waves are defined as the pattern of disruption brought on by energy's passage through a medium when sound travels away from its source. Pressure waves are produced by the vibration of objects and are known as sound waves. A sound source, such as the vibrating speaker's diaphragm in a stereo, produces the sound waves.

Thus, the students increase the amplitude of the sound waves of the music turn the volume up to create more energy. Hence option A is correct.
