Answer:
Hey
I am sure from what i know that your answer should be the following:
Modern technology is deeply tied to efficiancy and speed. Think of the knew 5G network it gives us very fast internet, or perhaps our very nessisitys such as our phone or cumputer. On a phone you have so much (thats to say you can acces alot easly); pictures videos dictionarys video games etc etc.
Answer:
when the center of gravity is within the washing area, the torque returns in the body to its initial position and is in a stable equilibrium
Explanation:
The concept of center of gravity is equivalent to the concept of center of mass, in this place all external forces applied can be considered.
When we analyze the balance of a body that is the torque it is the one that defines the balance
τ = F xd
If the torque tends to restore the body to the initial position the balance is stable, but if the torque has to increase the body's rotation the balance is unstable
. When the body tends to rotate the torque with respect to the pivot point at the base it decreases because the distance from the center of gravity to the end of the base decreases in value, but it has to return it to the initial position, the balance is stable. The critical point of this process is when the center of gravity is at the limit of the body base area in this case the torque is zero; If the body rotates a little more the center of gravity is outside the base, the torque changes sign and has to increase the turn, going to an unstable balance.
In summary, when the center of gravity is within the washing area, the torque returns in the body to its initial position and is in a stable equilibrium.
Mario Molina helped to bring about the 1987 Montreal Protocol on substances that result in depletion of the Ozone Layer.
<h3>What is ozone layer?</h3>
The topmost layer of the atmosphere which protect the harmful UV rays from the Sun to reach the Earth surface.
Mario Molina has the great contribution in science field. He tried hard and succeeded in passing an international agreement to eliminate CFCs also called as Chloro Fluoro Carbons and other ozone-depleting chemicals.
These CFCs were used in jet planes which depleted the ozone layer and a hole was observed over Antarctica.
