Similarities and differences between high pitch and low pitch

1 answer:

4 0

You can hear a difference between these two sounds. That is because their pitch isdifferent. Pitch depends on the frequency of a sound wave. ... High sounds have highfrequencies and low sounds have lowfrequencies.

The property of matter that determines the direction of heat flow is the

Kobotan [32]

Answer:

Temperature

Explanation:

The heat flows from high temperature to low temperature.So we can say that temperature is the property that decide the direction of heat flow.Like in the electric system current flow high voltage to low voltage ,so we can say that voltage is the property which determine the direction of current flow.

So the answer is Temperature.

One day you are driving your friends around town and you drive quickly around a corner without slowing down. You are going at a

Novay_Z [31]

Answer:

1.60 g

Explanation:

From the attached file below:

we can deduce that:

$v = v_x =v_y = 20 \ m/s \\t = 2s$

The distance traveled by 2 s will be:

x = vt

x = 20 m/s × 2 s

x = 40 m

The length is quarter of the circle with radius r,

so; if 2 πr = 4 x

Then radius (r) will be:

$r = \frac{4x}{2 \pi}\\\\r = \frac{4*40}{2 \pi}$

r = 25.5 m

The centripetal acceleration can be expressed as:

$a = \frac{v^2}{r}$

so;

$a = \frac{(20 \ m/s^2)}{25.5 \ m}$

a = 15.7 m/s²

the magnitude of the acceleration experienced by your unfortunate passengers in terms of acceleration due to gravity is then determined by the equation:

$a' = \frac{a}{g} g$

$a' = \frac{15.7 \m/s ^2}{9.81 \ m/s^2}\ g$

$a' = 1.60 \ g$

∴ The magnitude of the acceleration experienced by your unfortunate passengers during the turn = 1.60 g
