Answer:

The percentage of mass recover from recrystallization = 24.69 %

Explanation:

Given that

Initial mass of crude acetanilide = 166 gm

The mass after recrystallization = 125 gm

The mass recover from recrystallization= 166 - 125 gm

The mass recover from recrystallization= 41 gm

The percentage of mass recover from recrystallization can be find as

percentage\ of\ mass\ recover\ from\ recrystallization\ =\dfrac{166-125}{166}

The percentage of mass recover from recrystallization = 24.69 %

Harlamova29_29 [7]

Answer: Increase in wave frequency

Explanation:

When we talk about acoustics we are dealing with sound waves, and one of their main components along with the velocity and wavelength is the <u>frequency.</u>

In this sense, the frequency of any wave refers to how fast (or slow) a wave oscillates. For example, in the especific case of sound waves when the oscillation is faster, the frequency is higher and the pitch gets higher as well.

If you can simply pour sand into a cup then why is it not a liquid?
sleet_krkn [62]
If you, for example, poured it onto a wide cup with a volume equal to the total volume of the sand particles, the sand would not spread out to fill the container but would bunch up together in the middle.

A cosmic ray travels 60.0 km through the earth's atmosphere in 500 μs , as measured by experimenters on the ground. You may want
zavuch27 [327]

Answer:

t' = 458.26 μs

Explanation:

given,

distance traveled by the cosmic ray = 60 Km

time = 500 μs

time taken for the journey according to cosmic ray = ?

now,

 v =\dfrac{distance}{time}

 v =\dfrac{60\times 10^3}{500\times 10^{-6}}

      v = 1.2 x 10⁸ m/s

according to time dilation formula

t' = t\sqrt{1-\dfrac{v^2}{c^2}}

t' = 500\sqrt{1-\dfrac{(1.2\times 10^8)^2}{(3\times 10^8)^2}}

     t' = 500 x 0.9165

    t' = 458.26 μs

A pendulum is made of a small sphere of mass 0.250 kg attached to a lightweight string 1.20 m in length. As the pendulum swings
forsale [732]

Answer:v=2 m/s

Explanation:

Given

Length of string L=1.2 m

mass of pendulum m=0.25 kg

maximum inclination with vertical \theta =34

vertical Rise of Pendulum from its mean position  is given by

\Delta h=L(1-\cos \theta )

Conserving Energy at top and bottom point

Potential Energy of sphere is converted into kinetic energy of sphere

mgL(1-\cos \theta )=\frac{mv^2}{2}

v=\sqrt{2gL(1-\cos \theta )}

v=\sqrt{2\times 9.8\times 1.2(1-\cos 34)}

v=\sqrt{4.021}

v=2 m/s

Two unknown resistors are connected together. When they are connected in series their equivalent resistance is 15 Ω. When they a
DochEvi [55]

Explanation:

Let x and y are two unknown resistors. When they are connected in series their equivalent resistance is 15 Ω. When they are connected in parallel, their equivalent resistance is 3.3 Ω.

For series combination,

x+y=15 ......(1)

For parallel combination,

\dfrac{1}{x}+\dfrac{1}{y}=3.3 ....(2)

We need to find the resistances of these resistors. Solving equation (1) and (2) we get :

x = 0.29 and y = 14.7

Hence, the resistances of these resistors are 0.29 ohms and 14.7 ohms.
