Answer:

eardrum is the correct answer

hope this helps ❤️

Explanation:

Sound waves enter the ear canal and cause the eardrum to vibrate. Three small bones transmit these vibrations to the cochlea. This produces electrical signals which pass through the auditory nerve to the brain, where they are interpreted as sound.

Answer:

In hydrogeology, groundwater flow is defined as the "part of streamflow that has infiltrated the ground, entered the phreatic zone, and has been (or is at a particular time) discharged into a stream channel or springs; and seepage water." It is governed by the groundwater flow equation.

Complete Question

The complete question is shown on the first uploaded image

Answer:

The distance which the car skid is $l = \frac{v_i^2 }{2 * \mu_k * g }$

Explanation:

From the question we are told that

The initial velocity of the car is $v_i$

The coefficient of kinetic friction is $\mu_k$

According to the law of energy conservation

The initial Mechanical Energy = The final Mechanical Energy

$M_i = M_f$

The initial mechanical energy is mathematically represented as

$M_i = KE _o + PE_e$

where KE is the initial kinetic energy which is mathematically represented as

$KE = \frac{1}{2} m v_i^2$

And PE is the initial potential energy which is zero given that the car is on the ground

Now

$M_f = W_{\mu}$

Where $W_{\mu}$ is the work which friction exerted on the car which is mathematically represented as

$W_{\mu} = m* \mu_k * g * l$

Where $l$ is the distance covered by the car before it slowed down

$\frac{1}{2} m v_i^2 = m* \mu_k * g * l$

=> $l = \frac{v_i^2 }{2 * \mu_k * g }$

In an experiment to measure the wavelength of light using a double slit, it is found that the fringes are too close together to

Mandarinka [93]

Answer:

halve the slit separation

Explanation:

As we know that

In YDS experiment, the equation of fringe width is as follows

$\beta = \frac{\lambda D}{d}$

where,

D denotes the separation in the middle of screen and slits

d denotes the distance in the middle of two slits

And to increase the Δx we have to decrease the d i.e, the distance between the two slits

Hence, the first option is correct
