Answer:
The bigger balloon will have a larger area and would experience a greater buoyant force exerted on it which would make it even lighter than a smaller balloon and will have higher payload capacity than a smaller one.
Answer:
- magnitude : 1635.43 m
- Angle: 130°28'20'' north of east
Explanation:
First, we will find the Cartesian Representation of the and vectors. We can do this, using the formula
where its the magnitude of the vector and θ the angle. For we have:
where the unit vector points east, and points north. Now, the will be:
Now, taking the sum:
This is
Now, for the magnitude, we just have to take its length:
For its angle, as the vector lays in the second quadrant, we can use:
Answer A: It will rotate to the right
Answer B: it will rotate to the left
Answer C: 17.5 N
Answer D: 2.25 m
Answer:
BMI = 20.98 [kg/m^2]; Normal or Healthy Weight
Explanation:
Body mass index (BMI) is a person’s weight in kilograms divided by the square of height in meters. Therefore we must convert the height from centimeters to meters.
BMI = 68 / (1.8)^2
BMI = 20.98 [kg/m^2]
BMI Weight Status
Below 18.5 Underweight
18.5 – 24.9 Normal or Healthy Weight
25.0 – 29.9 Overweight
30.0 and Above Obese
So the weight status is Normal or Healthy Weight
