Do you think a moving skateboard has energy? Why or why not?
PLEASEEEEEE HURRY
Answer:
"Yes," a moving skateboard has energy.
When the skater seems to be in motion or throughout a movement, the potential energy converts itself into the kinetic form of energy, and then it becomes potential energy again.
Furthermore, somewhere after every movement, the same skateboarder was around a similar height, — in other words thus every time it is equally powerful.
The response is thus the right one.
Explanation:
Use the table of observed changes to answer the question.
Which changes shown in the table are physical changes?
2 and 4
2 and 3
1 and 4
1 and 2
Answer: 2 and 4
Explanation:
The way to find if a chemical change happened is if something major like a new substance is created, or if it is mixed with another chemical. If the structure of the chemical has changed, it is a chemical change. Gas, sound, or light as well as a temperature change is not affecting the structure of a chemical substance, meaning it is 2 and 4 which doesn't have anything that could cause its chemical structure to change.

When an organism uses chemical energy to move, some of it is lost as (blank) energy.
(science middle school answer pls)
Answer:
When an organism use chemical energy to move, some of it is lost as metabolic heat.
The term chemical energy is defined as the energy which is stored in the bonds of chemical compounds. It is given in the chemical reaction and mostly produces heat as a by-product, known as an exothermic reaction.
Energy changes as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are taken by organisms from the next level.
Thus, Metabolic heat is lost when an organism uses chemical energy to move.
...
Answer:
When an organism use chemical energy to move, some of it is lost as metabolic heat.

1. unimportant details
2. chemical properties
3. incorrect facts
4. physical properties
Answer:
Chemical properties
Explanation:
Water has a boiling point of 100°C or 373 KWater has melting point of 0°C or more exactly 273.16KThe density of water at 4°C is 1000kg/m^3Individual organisms have a variety of traits that make them different from each other. Traits such as fur color and eye color vary from one individual to another. What determines the traits of an individual organism?
Answer:
Traits can be determined mostly by genes but can be by environmental factors, or a combination of both. Traits can be qualitative (such as eye color) or quantitative (such as height or blood pressure) A given Trait is part of an individual's overall phenotype.

Who first discovered the phenomenon of radioactivity?
Answer:
Antoine Henri Becquerel
Explanation:
Though it was Henri Becquerel that discovered radioactivity, it was Marie Curie who coined the term. Using a device invented by her husband and his brother, that measured extremely low electrical currents, Curie was able to note that uranium electrified the air around it.

1. Using D10W and a vial of NaCl 4 mEq/mL, how many mL of NaCl are needed to prepare 250 mL of a
D10/NS solution?
a. 4.8mL
b. 9.6ml
c. 19.6mL
d. 154mL
To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.
