Answer:
A physical change is a change to the physical—as opposed to chemical—properties of a substance. They are usually reversible. The physical properties of a substance include such characteristics as shape (volume and size), color, texture, flexibility, density, and mass.

Hold on and let's discuss this realistically.
Because of gravity, there are two forces between the Earth and me. One draws me toward the Earth. The strength of that force is what I call my "weight". The other force draws the Earth toward me, and has the same strength.
The strength of these forces depends on the masses of the Earth and me. If the strength just tripled, that means that at least one of us just picked up a lot more mass. If the Earth suddenly became three times as massive, then the weight of everything and everybody on it would suddenly triple, and I'm pretty sure it would be the end of all of us before too long.
If it was only MY mass that suddenly tripled, that would mean that I had gone tearing through my house and the neighbour's house, eating everything in sight including the 2 couches, 3 dogs, and 6 TVs. Naturally, just as you would expect, my weight changed from 207 to 621, and my skin is stretched really tight.
ooohhh
The statement that indicate the examples of resource depletion that can occur due to technology is option B which is Certain chemicals are released into the air by cars, leading to acid rain.
<h3>What is resource depletion?</h3>
Resources depletion is the process in which resources or raw materials are been destroyed or been exhausted due to several human activities or technologies thereby by leading to harmful effects on the health and livelihood of humans.
Therefore, The statement that indicate the examples of resource depletion that can occur due to technology is option B which is Certain chemicals are released into the air by cars, leading to acid rain.

Answer:
1.6 s
Explanation:
To find the time in which the potential difference of the inductor reaches 24V you use the following formula:
V_o: initial voltage = 60V
R: resistance = 24-Ω
L: inductance = 42H
V_L: final voltage = 24 V
You first use properties of the logarithms to get time t, next, replace the values of the parameter:
hence, after 1.6s the inductor will have a potential difference of 24V
Answer:
The amount of potential energy stored in the magnetic field depends on both the strength of the magnet and the distance that another magnet or magnetic object is from it. ...
Explanation:
All objects have a gravitational force, no matter how small, but only some objects such as iron objects can have a magnetic force.
