Check the explanation
Explanation:
![\omega _{0} = 82\ rad/s](https://tex.z-dn.net/?f=%5Comega%20_%7B0%7D%20%3D%2082%5C%20rad%2Fs)
![\alpha = - 1.4\ rad/s^{2}](https://tex.z-dn.net/?f=%5Calpha%20%3D%20-%201.4%5C%20rad%2Fs%5E%7B2%7D)
![\Theta = ?](https://tex.z-dn.net/?f=%5CTheta%20%3D%20%3F)
![\omega _{f} = 0\ rad/s](https://tex.z-dn.net/?f=%5Comega%20_%7Bf%7D%20%3D%200%5C%20rad%2Fs)
![2*\alpha *\Theta = \omega _{f}^{2}-\omega _{0}^{2}](https://tex.z-dn.net/?f=2%2A%5Calpha%20%2A%5CTheta%20%3D%20%5Comega%20_%7Bf%7D%5E%7B2%7D-%5Comega%20_%7B0%7D%5E%7B2%7D)
![2*-1.4*\Theta = -82^{2}](https://tex.z-dn.net/?f=2%2A-1.4%2A%5CTheta%20%3D%20-82%5E%7B2%7D)
![\Theta = 2401.429\ radian = 2401.429*\frac{\pi }{180}\ degree = 41.91\ degree](https://tex.z-dn.net/?f=%5CTheta%20%3D%202401.429%5C%20radian%20%3D%202401.429%2A%5Cfrac%7B%5Cpi%20%7D%7B180%7D%5C%20degree%20%3D%2041.91%5C%20degree)
Each number in the wheel spans 360/12 = 30 degree
Therefore 41.91 degree corresponds to the number 29 on the wheel when the wheel spins clockwise.
Answer:
The correct answer is: macronutrients.
Explanation:
Nutrients are chemical substances found in food that, when consumed, allow the development, maintenance and functioning of our body.
Every time you eat a food, your body assimilates, transforms and takes advantage of its nutrients in order to live.
No single food can provide us with all the nutrients that the body needs. Only a healthy, varied and balanced diet will do it.
Types of nutrients
:
Nutrients can be essential (the body cannot synthesize them on its own and we must acquire them through food) or non-essential (our body produces them from other components). According to their proportion they are divided into
:
- macronutrients: they occupy most of the food and are consumed in grams. They are carbohydrates or carbohydrates (sugar, vegetables, fruit, cereals, etc); proteins (meat, fish, eggs, milk, etc.), fats or lipids (oils, seeds, nuts, milk and derivatives).
- micronutrients: we take them in micrograms. In this group we find vitamins and minerals. The main source is fruits and vegetables, although we also get them from most foods.
Water is another essential nutrient, without which we could not live and that helps all the physiological processes of the body to take place.
Nutrients are classified into:
-Energy nutrients: provide the energy the body needs to function. Macronutrients are the main source of energy. Among these are carbohydrates and fats and to a lesser extent proteins.
-Plastic nutrients: involved in the construction of body structures, maintenance and repair of tissues. Proteins and mineral salts belong to this group.
-Regulatory nutrients: participate in the body's regulatory processes. They are vitamins and minerals.
Answer: a.troposphere
Explanation: Most of the mass (about 75-80%) of the atmosphere is in the troposphere. Almost all weather occurs within this layer. Air is warmest at the bottom of the troposphere near ground level. Higher up it gets colder. Air pressure and the density of the air are also less at high altitudes.
In a balanced system, the total energy should always stay the same. The total energy is the sum of the potential and the kinetic energies. If the potential energy increases, then the kinetic energy should decrease. This happens to keep the system under a state of balance.
Develop a new technology to mitigate some of the environmental impacts associated with using the resource.
Reduce the rate at which the resource is consumed.
