Answer: The crust of the Earth has some permanent magnetization, and the Earth's core generates its own magnetic field, sustaining the main part of the field we measure at the surface. So we could say that the Earth is, therefore, a "magnet."
Explanation:
Answer:
A hypothesis. In science, a hypothesis is an idea or explanation that you then test through study and experimentation. Outside science, a theory or guess can also be called a hypothesis. A hypothesis is something more than a wild guess but less than a well-established theory. My hypothesis was right because although it was n educated guess it was still correct
The viscosity value decreased with the increase of temperature. The effect caused by temperature in the range studied was more important in the low range of temperature, whereas at high temperature, the viscosity showed less variation.The studies carried out in the present work indicated that the effect of temperature upon the viscosity of Galician honeys was prominent, and it is necessary to take into account this variable when the operation temperature is under 25°C, since below this value a small variation in temperature produces high changes in the viscosity value. On the other hand, different models to fit experimental values of viscosity/temperature have been proved. The glass transition temperature was determined necessarily since several models include this parameter in the equation, because it provides important information related to the viscosity value. All the models show a good behaviour but the best results were obtained using the Arrhenius one.
Answer:
The change of energy is 60J
Explanation:
We have a closed system, which receives 80 J of energy. It means this energy is entering the system. And also we have 20 J that is dissipating in the shape of heat.
Therefore the amount remaining in the system will be 80 - 20 = 60 J
It is recommended to change or service the automatic transmission fluid for every 30,000 miles. This is the ideal schedule for the average driver and will allow your transmission to run on well fluid continuously, which ultimately means a longer lasting and more efficient transmission. Even though there isn’t any damage in regular fluid changes, they recommend getting it changed every 30,000 to 60,000 miles for better outcomes on your transmission. But there are circumstances where a fluid change should be done sooner, and it will all rest on on your driving routines and other various factors. If you see to do some heavy towing, carrying, common stop-and-go driving, live in a very hot climate, or snow plowing, you should ponder getting your fluid changed sooner, perhaps every 15,000 miles
