Calculate their sine function values​

Physics
1 answer:
Stells [14]3 years ago
3 0

Sine value is defined in the following way

Explanation:

  • In a right triangle, the sine of an angle is the length of the opposite side divided by the length of the hypotenuse. Try this Drag any vertex of the triangle and see how the sine of A and C are calculated. The sine function, along with cosine and tangent, is one of the three most common trigonometric functions.
  • Let's start with the basic sine function, f (t) = sin(t). This function has an amplitude of 1 because the graph goes one unit up and one unit down from the midline of the graph. This function has a period of 2π because the sine wave repeats every 2π units.
  • Trigonometric sine calculator.

Sine calculator

In order to calculate sin(x) on the calculator:

Enter the input angle.

Select angle type of degrees (°) or radians (rad) in the combo box.

Press the = button to calculate the result.

Why might the current in a short circuit be higher than the current in the original circuit?
Sveta_85 [38]

Answer:

Hope this helps =)

Explanation:

The current in a short circuit may be very high because the resistance in the short circuit is probably less than the resistance in the original circuit.

A liquid with a density of 900kg/m 3 is stored in a pressurized, closed storage tank. The tank is cylindrical with a 10m diamete
Orlov [11]

Answer:

18.62 m/s

Explanation:

Given that:

A liquid with a density of 900 kg/m 3 is stored in a pressurized, closed storage tank.

Diameter of the tank = 10 m

The absolute pressure in the tank above the liquid is 200 kPa = 200, 000 Pa

At pressure of 200 kPa   ; the final velocity = 0

Atmospheric pressure at 5cm = 101325 Pa

We are to calculate the initial velocity of a fluid jet when a 5cm diameter orifice is opened at point A?

By using Bernoulli's theorem between the shaded portion in the diagram;

we have:

Pa \ + \ \frac{1}{2} \  \delta \ v^2_1 \ + \ \delta gy_1 = P + \delta gy_2

\frac{1}{2} \  \delta \ v^2_1 \ = P + \delta gy_2 -  \ \delta gy_1  - Pa

\frac{1}{2} \  \delta \ v^2_1 \ =  \delta g(y_2 -y_1 )+   ( P   - Pa )

v_1 \ =  \sqrt{ \frac {2 \ \delta g(y_2 -y_1 )+  2  ( P   - Pa )}{\delta}}

where;

Pa = atmospheric pressure = 101325 Pa

\delta = density of liquid = 900 kg/m³

v_1 = initial velocity = ???

g = 9.8 m/s²

y_1 = height of the hole from the buttom

y_2 = height of the liquid surface from the button

v_1 \ =  \sqrt{ \frac {2*900*9.8(7 -  0.5 )+  2  ( 200,000   - 101325 )}{900}}

v_1 = 18.62 \ m/s

Thus, the initial  velocity of the fluid jet  = 18.62 m/s

Measuring the size of a specific object might include which of these SI units?
defon

D. Meter, Kilogram

Explanation:

  • There are certain units for the measurements things which are around us.
  • This is the SI units for the measurement of the size of the objects.
  • SI units are international unit systems, they are one who accepted around the world.
  • It is called the International System of Units, used to expresses the phenomenon happens around us in a scientific method
  • Here, the meter is the unit for Length in the International System of Units and Kilogram is to represent the mass of the object in SI units system.
