Answer:

5 m

Explanation:

From the question,

v = λf....................... Equation 1

Where v = speed of the sound wave, λ = wavelength of the sound wave, f = frequency of the sound wave.

make λ the subject of the equation

λ = v/f..................... Equation 2

Given: v = 150 cm/s = 1.5 m/s, f = 0.3 hz.

Substitute these values into equation 2

λ = 1.5/0.3

λ = 5 m.

If fluorine was in ionic compounds with ions of each of the following atoms, how many fluorines would be needed?
nevsk [136]
<span>You forgot to post the list of "following atoms", but 

Fluorine ions have a -1 charge. So find the charges of the other ions and The number of Fluorines you'll need should match the </span>other ion's charge.

Dimensional formula of Amplitude ?​
jeka57 [31]

Answer:

The dimensional formula of the amplitude of a wave is given by,

[ M⁰L¹T⁰ ]

Where,

M = Mass

L = Length

T = Time

Derivation

The amplitude of wave = Maximum displacement

Since, the dimensional formula of displacement = [ M⁰L¹T⁰ ]

Therefore, the amplitude of a wave is dimensionally represented as [ M⁰L¹T⁰ ]

Two charged spheres are 8.45 cm apart. They are moved, and the force on each of them is found to have been tripled. How far apar
Aleonysh [2.5K]

Force between two charges is given by

F = \frac{kq_1q_2}{r^2}

here force is inversely depends on the square of the distance

so here if distance is decreased the force will increase'

now if force is tripled

\frac{3F}{F} = \frac{r^2}{r'^2}

initially distance between charges was 8.45 cm

3 = \frac{8.45^2}{r'^2}

r' = \frac{8.45}{\sqrt3}

r' = 4.88 cm

so the distance between charges is 4.88 cm now
