Answer:
"Emerging technologies, such as industrial robots, artificial intelligence, and machine learning, are advancing at a rapid pace. These developments can improve the speed, quality, and cost of goods and services, but they also displace large numbers of workers."
Explanation:
This means in the furture we will have many technologies doing our day to day life things.
Answer:
exothermic
Explanation:
An exothermic reaction is a chemical reaction that releases energy through light or heat. It is the opposite of an endothermic reaction. Expressed in a chemical equation: reactants → products + energy.
Answer:
below the horizontal.
Explanation:
This is a projectile motion problem. So we are going to use uniform motion and free-fall formulas.
Since what we want is the angle of the diver when hitting the water, we are going to search for the components of the final velocity and with them compute the angle.
For the free-fall part we know:
- ,
- ,
- (remember that the initial velocity in the vertical component is zero because at the begining he only has horizontal velocity).
For the uniform motion part:
Notice that we already have the final velocity in the x coordinate (uniform motion means that the velocity is constant).
For the final velocity in y coordinate we are going to use:
,
since we get
,
,
,
.
Now we can find the angle using the tangent function and the components of the final velocity. Remember that they are related as follow:
,
where is the angle below the horizontal (the angle we are searching for).
We have that
.
Answer: A Answers. Assuming that the terminal velocity doesn't change during the fall, then the kinetic energy would remain constant. However the terminal velocity decreases during the fall since the air becomes denser at lower altitudes.
Explanation:
What happens to the KE of an object when it slows down and heats up? - Quora. The kinetic energy goes down and the loss of the kinetic energy is through the production of heat energy. In real world this is due to friction, or an opposing force that decelerates the object, or a combination of both.
