Answer:
D) liquid and gas
Explanation:
The three main states of matter are:
- Solid: in solids, the molecules are bond together by strong intermolecular forces, so the molecules are not free to move. Therefore, a solid has a definite shape, so it does not take the shape of its container.
- Liquid: in liquids, molecules are not bond together, so they are free to move (still, there are some weak intermolecular forces which keep them close to each other). Since in liquids molecules can slide past each other, they take the shape of the container.
- Gas: in gases, molecules are totally free to move, so gases take the shape (and also the volume) of the container.
Based on the definitions above, we can conclude that the correct answer is
D) liquid and gas
True. Weight can change with the amount of gravity but mass will always stay the same.
<span>To find the gravitational potential energy of an object, we can use this equation:
GPE = mgh
m is the mass of the object in kg
g = 9.80 m/s^2
h is the height of the object in meters
GPE = mgh
GPE = (0.700 kg) (9.80 m/s^2) (1.5 m)
GPE = 10.3 J
The gravitational potential energy of this can is 10.3 J</span>
Answer:
A. Objects 1 and 2 will not move, and objects 3 and 4 will accelerate
upward.
Explanation:
A is correct as the weight in Objects 1, and 2 is greater than the person's push force; however it is on the ground meaning it is at it's stable state meaning the box couldn't be moved downwards anymore. And The newtons in 3 and 4 are the same
B is incorrect as Object 3 and 4 has a less Newton weight than newton force
C is incorrect as Object 1 and 2 has a greater Newton weight than newton force
D is incorrect as Object 1 and 2 wouldn't move downwards
Hope this helps!
The correct answer among all the other choices is 4. This is the number of the lowest energy level that contains an f sublevel. Thank you for posting your question. I hope that this answer helped you. Let me know if you need more help.
