speed of sound is 343 Ms at 20 degrees Celsius. The frequency heard from the sound is 256 Hz. what is the sounds wavelength?

Lina20 [59]

S= 343m/s
F=256Hz

WL= 343ms/256-1
WL=V/F

= 1.339844m

What is the conclusion of coin and feather experiment?

valina [46]

Answer:

So the conclusion is that in presence of air net force acting downward reduces for feather and hence falls slower than coin. But in absence of air resistance, net downward force is just equal to force due to gravity which is same for both coin and feather and hence they fall down at the same rate.

The electric flux through a spherical surface is 1.4 ✕ 105 N · m2/C. What is the net charge (in C) enclosed by the surface?

Anit [1.1K]

Answer:

The value is $Q_{net} = 1.239 *10^{-6} \ C$

Explanation:

From the question we are told that

The electric flux is $\Phi = 1.4*10^{5} \ N\cdot m^2/C$

Generally the net charge is mathematically represented as

$Q_{net} = \Phi * \epsilon_o$

Here $\epsilon_o$ is the permetivity of free space with value

$\epsilon_o = 8.85*10^{-12} \ \ m^{-3} \cdot kg^{-1}\cdot s^4 \cdot A^2$

So

$Q_{net} = 1.4*10^5 * 8.85*10^{-12}$

=> $Q_{net} = 1.239 *10^{-6} \ C$
