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.
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.

You must use all of the tools in your design: lamp, tennis ball, golf ball, and yarn.
When the Moon passes between Sun and Earth, the lunar shadow is seen as a solar eclipse on Earth. When Earth passes directly between Sun and Moon, its shadow creates a lunar eclipse. Lunar eclipses can happen only when the Moon is opposite the Sun in the sky, a monthly occurrence we know as a full Moon.

Data just came in about the space pod's mission and the thrusters fired for exactly the same about of time and at the same force as they have in past missions. Nothing about the pod's thruster force was different. Based on this new evidence, neither of our previous claims could be true!
We are left with the same question: why didn't the pod dock like it was supposed to do?
What new theories do you have?
Answer:
: WHY DIDN'T THE POD DOCK LIKE IT WAS SUPPOSED TO DO?
ANSWER;
The force exerted by the thrusters caused the pod to change direction.
WHAT NEW THEORIES DO YOU HAVE?
ANSWER;
This pod moved differently because it was more massive.

if you dig a hole through the earth, from one hemisphere to the other, and drop a tennis ball into it, would it get stuck at the center, since thats where gravity's at, or would it pop up out the other side??
Answer:
Depending on which hemisphere it is, like western to eastern, It would most likely get stuck at the center. You would also have to put more things into thought like acceleration, velocity, and speed.
BUT since the question asked "would it pop out the other side?", I'm assuming it's talking about northern to southern hemisphere. so in that case it would pop out the other side since gravity makes things go downwards.
Answer:
We drop a tennis ball into the hole. The stone is pulled down towards the center of the earth. It falls all the way to the middle of the earth once it reaches the middle, theres no more pull of gravity. ... It would go up a ways, then (due to the pull of gravity) fall back in the other direction, back towards the center

A car that is driving at the flat bottom of the hill would have ______ potential energy and _______ kinetic energy.
- High
- Low
- Equal
Answer:
Low Potential energy and High Kinetic energy
Explanation:
Hope this helps and have a good day! Apologies if it's wrong.<3
Answer:
Low, high
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).

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.
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.
