Answer:
The number of minutes in an hour - constant
Systolic blood pressure - variable
Freezing temperature of water in degrees Kelvin - constant
Ratings of daily anxiety - variable
Explanation:
A variable speaks of something that change while a constant is something that doesn't change.
The number of minutes in an hour is always constant which is 60.
Systolic blood pressure refers to the amount of pressure in your arteries during the contraction of your heart muscle and this changes base on the work done by the heart thus will be a variable.
Freezing temperature of water in degrees kelvin is always constant and it is 273.2 K.
Ratings of daily anxiety will be a variable because daily anxiety differs for different challenges of life.
The fountain is 5.213m high.
- Any shape's perimeter, or route around it, may be described by its circumference. In other words, the perimeter is another name for the circumference, which makes it easier to determine how long a shape's boundary is. The measurement of the circle's boundaries is known as the circumference or perimeter of the circle.
- circumference of pool = 23.8m
- 2πr = 23.8m
- r = 3.788m
- The angle formed between the horizontal line and the line of sight of a certain observer is known as the angle of elevation. The angle of elevation, as implied by its name, refers to the angle created when an item is viewed from below by the observer and their line of sight.
- angle of elevation of fountain = 54°
- let height of fountain be "h"
- Tan(54°) = h/r
- h = Tan(54°)*r
- h = 1.37638192 * 3.788
- h = 5.213m

<span>The density of air is about 1.29 kg/m^3, of helium .169 kg/m^3, and of carbon dioxide 1.98 kg/m^3. So the pitch would be highest for helium, in the middle for air, and lowest for CO2.</span>
Explanation:
Given that,
(a) Work done by the electric field is 12 J on a 0.0001 C of charge. The electric potential is defined as the work done per unit charged particles. It is given by :
(b) Similarly, same electric field does 24 J of work on a 0.0002-C charge. The electric potential difference is given by :
Therefore, this is the required solution.
"Though a force, or a resulting sum of forces, may be centripetal, there is not an actual "Centripetal Force" that would appear on an FBD. Since an FBD is a diagram of physical forces at work upon a body, and a centripetal force is not the reaction of some physical object upon another, it would not be proper to show it. You might have a tension force, a weight force, a normal force, electric forces, magnetic forces, or any number of reactions, but actually labeling any of them "centripetal" would be unconventional".
