Answer:
Explanation:
reactance of inductor = wL = 2 X 3.14 X 60 X 1.2 X 10⁻³ = .45 ohm.
reactance of capacitor = 1/wC = 1/( 2 X 3.14 X 60 X 1.8 X 10⁻⁶ ) = 1474.4
Impedence of the circuit =[ R² + ( I/wC - wL) ]¹/² = [250² + ( 1474.4-.45 )]¹/²
Impedence = 1495 ohm.
RMS Voltage = 120/ 1.414 = 84.86 V
current = 84.86 / 1495 = 0.0576
Potential over resistance = 0.0576 x 250 = 14.2 V.
Answer: 7.734 m/s
Explanation:
We have the following data:
The angle at which the water ballon was thrown
The horizontal distance of the water ballon
The acceleration due gravity
We need to find the initial velocity at which the water ballon was thrown, and we can find it by the following equation:
(1)
Where is the total time the water ballon is on air
On the other hand, when we talk about parabolic motion (as in this situation) the water ballon reaches its maximum height just in the middle of this parabola, when and the time is half the time it takes the complete parabolic path.
So, if we use the following equation, we will find :
(2)
Isolating :
(3)
Remembering :
(4)
Substituting (4) in (1):
(5)
Isolating :
(6)
(7)
Finally:
Soils are composed of organic matter (stuff that used to be alive, like plants and animals) and small inorganic matter. There are three basic soil types: sand, silt, and clay. Sand is comprised of tiny rock fragments and is the roughest in texture. Clay becomes sticky or greasy when wet, and very hard when dry.
The answer is going to be C, Bacteria. Therefore the organisms that are used to manufacture human insulin would be bacteria.
