Answer:

Explanation:

Hydrostatic pressure at any height below the water surface is calculated by P=hdg where h is the height below the open water surface, d is the density of water and g is the acceleration due to gravity. So if you want to calculate gauge pressure at height h then use formula P=hdg+P∘ where P∘ is atmospheric pressure

1. A Zambeef delivery track travels 18 km north, 10 km east, and 16 km south. What is its final displacement from the origin?
Amiraneli [1.4K]

Answer:

10.2 km

Explanation:

Displacement is the shortest distance from your original position after movement.

Now, the Zambeef delivery truck moves 18 km north and then 10 km east and then 16 km south.

This means that vertically the truck is 2km short of the 18 km he travelled north..

So we can find the displacement using pythagoras theorem..

Let d be the distance from the current position to the initial position.

Thus;

d² = 2² + 10²

d² = 4 + 100

d = √104

d ≈ 10.2 km

I have attached a diagram showing the direction of this displacement

Which type of motor is shown below?
Viefleur [7K]

Answer:

AC motor........A

Explanation:

Plato, an AC motor is much simpler than a DC motor.  As alternating current passes through the coil, it becomes magnetized.  Since the current is alternating, the north and south ends keep switching.

what are the horizontal and vertical components of a vector that is 25units long with an angle of 130 degrees​
AlekseyPX

Answer:

The horizontal component of the vector ≈ -16.06

The vertical component of the vector ≈ 19.15

Explanation:

The magnitude of the vector, \left | R \right | = 25 units

The direction of the vector, θ = 130°

Therefore, we have;

The horizontal component of the vector, Rₓ = \left | R \right | × cos(θ)

∴ Rₓ = 25 × cos(130°) ≈ -16.06

<em>The horizontal component of the vector, Rₓ ≈ -16.06</em>

The vertical component of the vector, R_y = \left | R \right | × sin(θ)

∴  R_y = 25 × sin(130°) ≈ 19.15

<em>The vertical component of the vector, R</em>_y<em> ≈ 19.15</em>

(The vector, R = Rₓ + R_y

\underset{R}{\rightarrow} = Rₓ·i + R_y·j

∴ \underset{R}{\rightarrow} ≈ -16.07·i + 19.15j)
