Answer:2.4m

Explanation:

Velocity=360m/s

Frequency=150Hz

Wavelength=velocity ➗ frequency

Wavelength=360 ➗ 150

Wavelength=2.4m

A saturated solution is formed by keeping 48 gram of a salt in 200 gram of water at 35°C. calculate the solubility of the salt.

viva [34]

The solubility of the salt. : 24 g/100 g solvent(water)

<h3>Further explanation</h3>

Given

48 gram of a salt in 200 gram of water at 35°C

Required

The solubility of the salt.

Solution

Solubility : the amount of a substance that can be dissolved in a solvent

Can be formulated(for 100 g solution)⇒grams solute per 100 g of solvent(100 ml water)

$\tt solubility=\dfrac{mass~solute}{mass~solvent}\times 100$

Input the value :

$\tt solubilty=\dfrac{48~}{200~g}\times 100=24~g$

Answer:

X(t) = 13/13 cos(12t+α)

C =13/13

π/6 s

Explanation:

(A) A body with mass 200 g is attached to the end of a spring that is stretched 20 cm by a force of 9 N. At time t = 0 the body is pulled 1 m in to the right, stretching the spring, 3 set in motion with an initial velocity of 5 m/s to the left.

(a) Find X(t) in the form c • cos(w_o*t— α)

(b) Find the amplitude 3 Period of motion of the body 1

mass: m = 200g = 0.200 kg

displacement: ΔX = 20 cm = 0.20 m

Spring Constant: K = 9/0.20 = 45 N/m

IV: X(0) = 1m V(0) = -5 m/s

Simple Harmonic Motion: c•cos(cosw_t— α) = X(t)

Circular Frequency: w_o = √k/m= √36/(0.20) = 13 rad/s

X(0) = 1m =c_1

X'(0) = V(0) = c_2*w_o/w_o

= -5/12 = c_2

"radians Technically Unitless"

Amplitude: c = √ci^2 + c^2 ==> √1^2 + (-5/12)^2 = 1 m =13/13 = c

X(t) = 13/13 cos(12t+α)

since, C>0 : damped forced vibration c_1>0, c_2>0

phase angle 2π+tan^-1(c_2/c_1)

=2π+tan^-1(-5/12/1)= 5.884

period: T =2π/w_o

=π/6 s
