Correct answer choice is:

C. Volley principle (FREQUENCY MATCHING)

Explanation:

Volley theory declares that groups of neurons of the hearing rule counter to a noise by firing action potentials imperceptibly out of the stage with one another so that when connected, a higher pulse of sound can be encoded and transmitted to the brain to be examined.

The displacement vector A and B when added together , give the resultant vector R so that R= A+B use the data in the drawing and

Salsk061 [2.6K]

The addition of vectors involve both magnitude and direction. In this case, we make use of a triangle to visualize the problem. The length of two sides were given while the measure of the angle between the two sides can be derived. We then assign variables for each of the given quantities.

Let:

b = length of one side = 8 m
c = length of one side = 6 m
A = angle between b and c = 90°-25° = 75°

We then use the cosine law to find the length of the unknown side. The cosine law results to the formula: a^2 = b^2 + c^2 -2*b*c*cos(A). Substituting the values, we then have: a = sqrt[(8)^2 + (6)^2 -2(8)(6)cos(75°)]. Finally, we have a = 8.6691 m.

Next, we make use of the sine law to get the angle, B, which is opposite to the side B. The sine law results to the formula: sin(A)/a = sin(B)/b and consequently, sin(75)/8.6691 = sin(B)/8. We then get B = 63.0464°. However, the direction of the resultant vector is given by the angle Θ which is Θ = 90° - 63.0464° = 26.9536°.

In summary, the resultant vector has a magnitude of 8.6691 m and it makes an angle equal to 26.9536° with the x-axis.

A bicycle tire is spinning counterclockwise at 2.70 rad/s. During a time period At 1.90 s, the tire is stopped and spun in the o

Naddik [55]

Answer:

a) -5.40 rad/s

b) -2.842 rad/s²

Explanation:

The direction is important in dealing with such questions. Clockwise is considered negative and counterclockwise is considered positive

a) Δω = final angular velocity - initial angular velocity

= -2.70 rad/s - 2.70 rad/s

= -5.40 rad/s

b) ∝ = Δω/Δt = (-5.40 rad/s)/1.90s = -2.842 rad/s²

En la Tierra un volcán puede expulsar rocas verticalmente hasta una altura máxima H. A) ¿A qué altura (en términos de H) llegarí

Nonamiya [84]

A) 2.64 H

The maximum height that the expelled rock can reach can be found by using the equation:

$v^2-u^2 = 2gd$

where

v = 0 is the velocity at the maximum height

u is the initial velocity

g is the acceleration of gravity

d is the maximum height

Solving for d,

$d=\frac{-u^2}{2g}$

We see that the maximum heigth is inversely proportional to g. On the Earth,

$d=H$ and $g=g_e = -9.81 m/s^2$

So we can write:

$\frac{H}{H'}=\frac{g_m}{g_e}$

where H' is the maximum height reached on Mars, and $g_m = -3.71 m/s^2$ is the acceleration of gravity on Mars. Solving for H',

$H' = \frac{g_e}{g_m}H = \frac{-9.81}{3.71}H=2.64 H$

B) 2.64T

The time after which the rock reaches the maximum height can be found by using

$v=u+gt$

where

v = 0 is the velocity at the maximum height

u is the initial velocity

Solving for t,

$t=\frac{v-u}{g}$

The total time of the motion is twice this value, so:

$t=2\frac{v-u}{g}$

So we see that it is inversely proportional to g.

On the Earth, t = T. So we can write:

$\frac{T}{T'}=\frac{g_m}{g_E}$

where T' is the total time of the motion on Mars. Solving for T',

$T' = \frac{g_e}{g_m}T=\frac{-9.81}{-3.71}T=2.64T$

Two cylindrical containers are placed on a turntable. canister A is empty; canister B contains lead shots. each canister is the

devlian [24]

Answer:

c) both containers slide off the turntable at the same turntable speed.

Explanation:

The greater the mass of the cylinder, the greater the centrifugal force acting on it. That makes up for the greater force needed to move the heavier cylinder.
