Define in your own words solubility
Andrews [41]
If something is water-soluble, then that means the substance can be dissolved in water. 

So... (water) solubility would be the quality of a substance that allows it to be dissolved in water

The ball was kicked in the air and it iss about to hit the . if horizonta componenet of its final velocity is 10m/s and vertical
erastovalidia [21]

Answer:

The magnitude of the final velocity is 14.14 m/s

Explanation:

The horizontal component of the final velocity and vertical component of the final velocity, forms a perpendicular vector. To determine the magnitude of the final velocity, we sum the two vectors.

To add two perpendicular vector, Pythagoras principle is used.

V^2 = V_x^2 +V_y^2\\\\V = \sqrt{V_x^2 +V_y^2}\\\\V =  \sqrt{(10)^2 +(-10)^2} =14.14 m/s

The magnitude of the final velocity is 14.14 m/s

In which situations is gravitational potential energy present? Check all that apply.
lukranit [14]
A person walks up a flight of stairs √
Wind lifts a balloon into the air √
A weightlifter holds a barbell straight overhead √

Gravity is used in most real world examples because if not of gravity everyone would be floating all around ^-^

Hope this helps ;p

A steel rod has a radius of 10mm and a
ss7ja [257]
Given a steel rod:
Radius = r = 10 mm = 0.010 m.
Length L = 1 m.
Tensile Force = F = 100 kN.
Young's Modulus = Y = 2.0 &* 10¹¹ Nm⁻²

a) Stress = Force/cross sectional area
σ = F / A
= 100,000 /(π 0.010²) Pa
= 318.309 MPa

b) Y = (F/A) / (ΔL/L)
Elongation ΔL = L F / (A Y)
= L σ / Y
= 1 * 318.309 * 10⁶ / 2.0 * 10¹¹ m
= 1.591 mm

c) Percentage elongation : ΔL/L * 100 = 0.1591 %

Two children, Ferdinand and Isabella, are playing with a waterhose on a sunny summer day. Isabella is holding the hose in herhan
AVprozaik [17]

Answer:

84%

Explanation:

g = Acceleration due to gravity = 9.81 m/s²

y_0=1\ m

x = 10 m

t = Time taken

v_0 = 3.5 m/s (assumed, as it is not given)

A_0=\pi 1.5^2

We have the equation

y=y_0+ut+\dfrac{1}{2}gt^2\\\Rightarrow 0=y_0-\dfrac{1}{2}gt^2\\\Rightarrow t=\sqrt{\dfrac{2y_0}{g}}\\\Rightarrow t=\sqrt{\dfrac{2\times 1}{9.81}}\\\Rightarrow t=0.45152\ s

x=x_0+vt\\\Rightarrow 10=0+v0.45152\\\Rightarrow v=\dfrac{10}{0.45152}\\\Rightarrow v=22.14741\ m/s

From continuity equation we have

Av=A_0v_0\\\Rightarrow A=\dfrac{A_0v_0}{v}\\\Rightarrow A=\dfrac{\pi 1.5^2\times 3.5}{22.14741}\\\Rightarrow A=1.11706\ cm^2

Fraction is given by

f=\dfrac{A_0-A}{A_0}\times 100\\\Rightarrow f=\dfrac{\pi 1.5^2-1.11706}{\pi 1.5^2}\times 100\\\Rightarrow f=84.196\ \%\approx 84\ \%

The fraction is 84%
