Write a word problem involving potential energy using the following variables: Potential Energy = 16 J
Acceleration due to gravity on Earth = 9.8 m/s^2
Mass = 7 kg
Think about what information you are missing and what the problem could be asking you to solve. Make sure to include the solution to your problem. (Potential energy = 9.8 x mass x height)

Write a word problem involving kinetic energy using the following variables: (Kinetic energy = 0.5 x mass x speed^2)

•Kinetic energy = 316 J
•Speed = 10 m/s

Think about what information you are missing and what the problem could be asking you to solve. Make sure to include the solution to your problem.

Answers

Explanation:

1st.

potential energy = 16 j

acceleration d t gravity = 9.8 m/s²

mass = 7 kg

we know

pe = m×g×h

16 = 7 × 9.8 × h

16 = 68.6h

16/68.6 = h

h = 2.16

2nd :

ke = 316 j

s = 10

we have

ke = 0.5×m×s²

316 = 0.5 × m × 10²

316 = 0.5 × m × 100

316 = 50m

316/50 = m

6.32 = m

m = 6.32 kg

may be check it once cuz I'm also not perfect at numericals too . I'm just 14 yo girl lol.

hope this helps :)

A group of students is tasked with developing a checklist for determining whether a material undergoes a chemical or physical change. The students make a preliminary list of properties that they can test and classify each as either a chemical or physical property.

Chemical Property Physical Property
bubbles when treated with acid color
burns when placed in a candle flame odor
density hardness
boiling point mass
dissolves in water melting point
Several other students in the class claim that the checklist is incorrect.

What change should the group make to the checklist to correct their mistake?


Boiling point and density should be moved to the physical property side of the list, and color and odor should be moved to the chemical property side of the list.


Boiling point and density should be moved to the physical property side of the list, and hardness and mass should be moved to the chemical property side of the list.

Taylor created the following table to compare the three types of rocks. What correction needs to be made to the information in the table?

Examples of igneous rock are sandstone and limestone and examples of sedimentary rock are granite and basalt.

Examples of igneous rock are granite and marble and examples of metamorphic rock and basalt and gneiss.

Metamorphic rocks are made from the cooling and hardening of sediment and igneous rock is made from high heat and pressure causing chemical change.

Igneous rocks are the cooling and hardening of magma or lava and sedimentary rock is made of sediment cemented together.

Answers

Igneous rocks are the cooling and hardening of magma or lava and sedimentary rock is made of sediment cemented together.

Igneous rocks are formed by cooling and hardening of sediment. The examples of igneous rocks include granite and basalt. Metamorphic rocks are formed by the treatment of high heat and pressure. The examples of metamorphic rocks are marble and gneiss.

What are Igneous rocks?

Igneous rock or magmatic rock, is one of the three main rock types, and the other rocks being sedimentary and metamorphic rocks. Igneous rock is formed through the cooling and solidification of the magma or lava in the volcano. The magma can be derived from partial melts of existing rocks in either a planet's mantle or the crust.

Metamorphic rock are formed from other type of rocks, however they have been substantially changed from their original igneous, sedimentary, or earlier metamorphic forms. Metamorphic rocks form when the rocks are subjected to high temperature, high pressure, hot mineral-rich fluids or, more commonly, some of the combination of these factors.

Does a tree falling over in a forest make a sound if there is no receptor (human or animal ear) to hear it? In your answer, describe why you think it does or does not. Describe how you would test your hypothesis. Use relevant terms.

Answers

It does make sound, just because there are no receptors does not mean that an object does not make sound. For example, whales communicate ona frequency higher then our ears can hear, however, we know that they still make sound. Another example is thunder; If you were far away to see thunder but not hear it, does it make sound? It does. Objects make sound by vibrating, there is no connection to sound and the presence of a receptor.

Yes. A tree falling over in a forest makes a sound even there is no receptor (human or animal ear) to hear it.

What is sound?

In terms of physics, sound is a vibration that travels through a transmission medium like a gas, liquid, or solid as an acoustic wave. Sound is the reception of these waves and the brain's perception of them in terms of human physiology and psychology. Only acoustic waves with frequencies between roughly 20 Hz and 20 kHz, or the audio frequency range, can cause a human to have an auditory sensation.

If sound is defined as air vibrations, then the falling tree most definitely creates sound because it causes air vibrations. A recorder with a microphone could undoubtedly capture those vibrations as sound even if no one or any other animal was around to hear it.

Answer:

Explanation:

The potential energy for the car would be low as it is on the flat bottom of the hill. Since it is still driving, it does have some kinetic energy. I'm assuming that it is currently moving at a constant velocity, so the kinetic energy would remain high (remember, the kinetic energy of an object is the energy that it possesses due to its motion).
