Answer:
The difference is in who or what is observing the speed.
Explanation:
Giving that speed is relative between the objects and the reference point from which it is being observed.
It is concluded that speed alone has no direct effect on a moving object, hence it is just a determining unit for the difference in distance between two objects.
Therefore, in this case, the difference is in who or what is observing the speed.
The answer is photosynthesis. The plant converts CO2, Sunlight, and H2O (water) into sugars which acts as their "food" and oxygen which we use to breathe.
Temperature is only a measure of the average heat. It doesn't measure the quantity of heat. Even if a small cup of tea is really hot, it's so small. An iceberg is huge, and although cooler, will have much more heat, even if it's temperature is low
Answer:
A concave lens is exactly the opposite with the outer surfaces curving inward, so it makes parallel light rays curve outward or diverge. That's why concave lenses are sometimes called diverging lenses.
To solve this problem it is necessary to apply the concepts related to Newton's second Law and its definition of density.
By Newton's second law we understand that,
F = ma
Where,
m = mass
a = acceleration (at this case the gravity acceleration)
In the case of density, we know that it is described as the proportion of mass versus volume, that is,
Where,
m = mass
V = Volume
The total tension of the AB cable would be given by the tension exerted upwards by the water and the tension exerted by the weight, therefore,
Mass can be expressed as,
Therefore the tension in cable AB is 6103.94N
