Answer:
i belive 1 m/s
Explanation:
dividing displacement from time it should be 1 cuz 5/5 is 1
please tell me if right!
Answer:
Explanation:
let t be time since the second diamond is released
a) y = ½g(t + 1)²
b) y' = ½g(t)²
c)
25 = ½g(t + 1)² - ½gt²
25 = ½g(t² + 2t + 1) - ½gt²
25 = ½gt² + gt + ½g - ½gt²
25 = g(t + ½)
t + ½ = 25 / g
t = (25 / g) - ½
t = (25 / 9.8) - ½
t = 2.05102... ≈ 2.1 s
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.
When hot metal plate is placed in air at room temperature
Then due to temperature difference heat flow will start from higher temperature to lower temperature
Here heat flow is from hot plate to room
The heat flow here is of two types
1. Convection flow of heat
In this phenomenon the thermal energy is transferred from plate to room by the thermal motion of air molecules in the room
2. Radiation heat flow
In this phenomenon the thermal energy is transferred by electromagnetic waves which transmits from the plate
This flow of heat will continue till the temperature of room and plate will become equal
