Predict what the MASS would be of something exerting a force of 45N on a spring scale. EXPLAIN how you got
a_sh-v [17]
The mutual forces of gravity between the Earth and an object on or near
its surface are (<em>mass of the object</em>) x (<em>acceleration of gravity on Earth</em>). 
These two forces are equal, and we call their strength the "weight" of
the object.  It's the number shown on the scale as long as nobody has
their thumb on the scale.  In this problem, the force is 45N .  (That's
about 10.12 pounds.)

The acceleration of gravity on Earth is about  9.8 meters per second² .

So    45N = (mass in kilograms) x (9.8 meters per second²)

Divide each side by  9.8 :      Mass = 45/9.8 = <u>4.59 kilograms</u>  (rounded)

The distance y3,red from the center of the pattern to the location of the third diffraction minimum of the red laser is 4.05 cm.
oksian1 [2.3K]

Answer:

L = a 1,929 10⁴ m

a = 0.1 mm = 0.1 10⁻³ m,     L = 1,929 m

Explanation:

The diffraction phenomenon is described by the expression

       a sin θ = m λ

Let's use trigonometry to find the breast

        tan θ = y / x

As the angles are very small

       tan θ = sin θ/ cos θ = sin θ = y / x

We replace

        a y / L = m λ

        L = a y / m λ

The red light has a wavelength of Lam = 700 nm = 700 10⁻⁹ m, in the third pattern it is m = 3

       L = a  4.05 10⁻² / (3 700 10⁻⁹)

       L = a 1,929 10⁴ m

To give a specific value we must know the width of the slit, suppose a value of  a = 0.1 mm = 0.1 10⁻³ m

       L = 1,929 m

Y_Kistochka [10]

Answer:

529.15 m/s

Explanation:

h = Maximum height = 70000 m

g = Acceleration due to gravity = 2 m/s²

m = Mass of sulfur

As the potential and kinetic energies are conserved

mgh=\dfrac{1}{2}mv^2\\\Rightarrow h=\dfrac{v^2}{2g}\\\Rightarrow v=\sqrt{2gh}\\\Rightarrow v=\sqrt{2\times 2\times 70000}\\\Rightarrow v=529.15\ m/s

The speed with which the liquid sulfur left the volcano is 529.15 m/s

how does the composition of a mixture of hydrogen and oxygen differ of hydrogen and oxygen differ from the composition of a comp
mafiozo [28]
In a mixture, there will be a solute and solvent. The hydrogen and oxygen are still two different atoms that just mixed together. But in a compound, the hydrogen and oxygen have a bond, making a new and bigger molecule. A mixture can easily be separated by physical means but a compound isn't.
