A natural system is formed when components are grouped together so as to perform a more specific function or use. In addition, this system is bound to exist without any human interference. Biological and non-biological components work hand-in-hand as they do nature processes.
I believe the answer is convection!
Answer: 272.82 drop/tile
Explanation:
Given that the Rain drops fall on a tile surface at a density of 4638 drops/ft2. There are 17 tiles/ft2. How many drops fall on each tile?
Tiles/ft^2 × drop/tiles = drop/ft^2
Tiles will cancel out. Leaving the answer to be drop/ ft^2
Substitutes all the magnitude of the above units.
17 × drop/tiles = 4638
Make drop/tiles the subject of formula
Drop/tiles = 4638/17
Drop/tiles = 272.82
Therefore, 272.82 drop/tile drops fall on each tile?
Answer:
The correct answer is:
Cardio exercise (B)
Explanation:
The frequency, intensity, time and type (FITT) model is a model is planning exercises that incorporate the four elements to be considered when choosing a personal goal and fitness level. Cardiovascular exercises mainly involves aerobic exercises that are aimed at strengthening the heart and lungs and making the working muscles more efficient at the use of oxygen. They also increase stroke volume (volume of blood pumped per minute) and resting heart rate. The following are what the model entails and how they fit best with cardio exercises:
- Frequency: This has to do with how often exercises will be done. Depending on the goal cardio exercises are normally recommended as moderate exercises for five or more days a week, and intense cardio for three days a week
- Intensity: This has to do with how hard you work during exercises. For cardio exercises, the heart rate monitor, perceived exertion and talk test are done to measure the intensity of the exercise
- Time: This has to do with how long each exercise session will last. For cardio exercises, the recommendation is 30 to 60 minutes for each session.
- Type: This is the actual activity that is chosen during the sessions, and it is chosen to avoid overuse injuries or weight loss plateus. The type of actvities for cardio includes exercises that are aimed at increasing the heart rate, like running, walking, cycling dancing etc.
The masses of the children may not be taken into account since these are towards the ground and directly affecting the bear. The net force is the difference of the forces since they are acting on opposite sides. The magnitude of this net force is equal to 2N and the sign is to where the greater force is from. Therefore, the force is directed towards the left.
