Answer:
Explanation:
Given,
After two revolutions, angular speed = 0.5 rev/s
Angular speed after 8 revolution = ?
Using equation of circular motion
Now, Angular speed after 8 revolution
Hence, the angular speed after 8 revolution is equal to 1 rad/s.
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.
You have a point on a rectangular graph with coordinates (6, 8).
You want to describe the same location in polar coordinates ... R and Θ .
-- 'R' is the distance from the origin to the point.
-- 'Θ' is the angle you'd need to turn the x-axis counterclockwise
around the origin to make it pass through the point.
To change rectangular coordinates to polar coordinates:
R = √(x² + y²)
Θ = the angle whose tangent is (y / x) .
(6i + 8j) is the [Cartesian] vector that takes you from the origin to (6, 8) .
R = √(6² + 8²) = √(36 + 64) = √100 = 10
Θ = tan⁻¹ (8/6) = 53.13° (rounded)
In polar coordinates, the same point is 10 ∠53.13° .

Answer:
d = 18 m
Explanation:
Given that,
The speed of a baseball, v = 36 m/s
We need to find the distance from the mound to home plate if the ball takes 0.5 seconds to leave the pitcher's hand and cross the plate.
Let the distance be d. We can find it using the formula,
Speed = distance/time
or
So, the required distance is equal to 18 m.
