some of the characteristics described apply to both living and some nonliving things. Other characteristics are unique to living things. Which one characteristic do you think makes it most clear that a car is not a living thing?
Answer:
A car can not reproduce
Explanation:
MRS GREN is the acronym you use to classify if something is living or not
Movement
Respiration
Sensitivity
Growth
Reproduction
Excretion
Nutrition
If something can do all of these things then it is a living thing. If it can't do even one then it isn't living.

A student puts a beaker of boiling water where it touches a block of ice. Which two statements are true? A. Thermal energy will move from the boiling water to the ice. B. Thermal energy will move from the air to the ice. O C. Thermal energy will move from the ice to the air D. Thermal energy will move from the air to the boiling water.
A student puts a beaker of boiling water where it touches a block of ice. The two true statements are that the thermal energy will move from the boiling water to the ice and the thermal energy will move from the air to the ice. Therefore the correct options are options A and option B.
What is the boiling point?
It is a temperature at which the pressure exerted by the external atmosphere is equal to the vapor pressure of the substance.
The boiling point depends on atmospheric pressure, temperature, bond strength, and vapor pressure of the liquid.
As the water is boiling it means it has more thermal energy contained in it than the surrounding air and the ice is present at zero degrees.
As we know that heat is always transferred from the higher thermal potential to the lower thermal potential and as the boiling water has the higher thermal potential among the ice and the surrounding air thermal energy will move from the boiling water to the ice and the thermal energy will move from the air to the ice. Therefore the correct options are options A and option B.

Lila is a track and field athlete. She must complete four laps around a circular track. The track itself is a 400 meter track and it took her 6 minutes total to complete.
Which best describes her speed and velocity? (There are 60 seconds in 1 minute.)
Her speed is 4.4 m/s, and her velocity is 0 m/s.
Her speed is 1.1 m/s, and her velocity is 0 m/s.
Her speed is 0 m/s, and her velocity is 2400 m/s.
Her speed is 4.4 m/s, and her velocity is 4.4 m/s.
Answer:
v (speed) = S / t = 4 * 400 m / (6 * 60 sec) = 4.4 m/s
The average velocity is zero because there is no net vector displacement.
Answer:
A- Her speed is 4.4 m/s, and her velocity is 0 m/s.

Why does water that is frozen in an ice cube tray stay in the shape of a cube when it is
taken out of the tray?
A. The water particles can only slip past one another.
B. The water particles become locked in place.
C. The water particles stop moving completely.
D. The water particles grow bigger to fill the space.
Water freezes to form ice cubes. In this solid structure, particles are strongly bonded each other thus, the water particles become locked in place.
What is freezing point?Freezing point is the temperature at which the substance converts from liquid state to solid state. In solid state, all particles are strongly bonded together.
In water, particles in liquid state are free to flow and they are not locked at all. In gaseous state no definite shape or volume are there and particles are away from each other and they diffuse easily.
In solid state particles are not at all free to flow and thus they are locked in place. That's why water molecules are locked in place in a cube until they melt completely.

A rope exerts a 35N force on an object at an angle of 12N degrees above the horizontal. What horizontal and vertical components of the force?
Answer:
The horizontal component of the force, [tex]F_x= 34.24 \ N[/tex]
The vertical component of the force, [tex]F_y=7.28 \ N[/tex]
Explanation:
Given;
Force on the rope, F = 35 N
angle between the rope and the horizontal = 12 °
The horizontal component of the force is given by;
[tex]F_x = Fcos \theta\\\\F_x = 35cos(12^0)\\\\F_x = 34.24 \ N[/tex]
The vertical component of the force is given by;
[tex]F_y = Fsin\theta\\\\F_y = 35sin(12^0)\\\\F_y = 7.28 \ N[/tex]

A 50 kg boy runs and jumps with a forward velocity of 1.5 m/s into a 125 kg stationary boat.
What is the final velocity of the boy/boat system?
0.43 m/s, forward
0.43 m/s, backward
1.1 m/s, forward
1.1 m/s, backward
Answer:
0.43 m/s, forward
Explanation:
i just took the test
A 50 kg boy runs and jumps with a forward velocity of 1.5 m/s into a 125 kg stationary boat, then the final velocity of the boy boat system would be 0.43 meters per second in the forward direction, therefore the correct answer is option A.
What is momentum?It can be defined as the product of the mass and the speed of the particle, it represents the combined effect of mass and the speed of any particle, and the momentum of any particle is expressed in Kg m/s unit.
As given in the problem A 50 kg boy runs and jumps with a forward velocity of 1.5 m/s into a 125 kg stationary boat, then the final velocity of the boy boat system,
By using the conservation of the momentum for the boy boat system,
50 × 1.5 + 0 = 175 × v
v = 75/175
v = 0.43 meters / second
Thus, the final velocity of the boy boat system would be 0.43 meters / second in the forward direction.

Choose the statement that is a misconception about a system in chemical equilibrium. (2 points) The rate of the forward reaction is equal to the rate of the backward reaction. The concentrations of the products and reactants dont change. The values of the products and reactants do not have to match each other. The reactions stop once equilibrium is reached.
Answer:
The correct answer is "The reactions stop once equilibrum is achieved"
Explanation:
A system is said to have attained equilibrium when the rate of forward reaction is the same/equal to the rate of backward reaction. The reaction below shows a chemical reaction that is at equilibrium
2N₂O₅ (aq) ⇄ 4NO₂ (aq) + O₂ (aq)
An equilibrium reaction is always a reversible reaction. When the system is at equilibrium (when there is a balance), the concentration of the reactants and products do not change despite the fact that reaction does not stop; what happens however is that the rate at which the reactant(s) are formed (backward reaction) will be equal to the rate at which the product(s) are formed (forward reaction).
From the explanation above, it can be deduced that "The reactions stop once equilibrum is achieved" is a misconception about a system in chemical equilibrium.

Consciousness is still a controversial issue among psychologists and philosophers is a true statement.
What is Consciousness?You experience everything as consciousness. It is the song that keeps playing in your head, the sweetness of chocolate mousse, the agonizing pain of a toothache, the passionate love you have for your child, and the painful realization that these emotions eventually pass.
From the earliest ages of antiquity till the present, the origin and nature of these experiences, also referred to as qualia, have remained a mystery.
Many contemporary analytic philosophers of mind, probably most notably Daniel Dennett of Tufts University, claim that consciousness is an illusion because they find it to be such an awful affront to what they feel should be a meaningless cosmos of matter and the void.
Therefore, Consciousness is still a controversial issue among psychologists and philosophers is a true statement.

Explanation:
When an electric magnet is brought near a cord with an electric current, the cord will most likely deflect away from the magnet because electric fields flowing through a wire generates its own magnetic field.
