Help with the two questions above? Correct answers?

LenKa [72]

(6) first choice: the frequency appears higher and wavelength is shorter.

The car approaches a stationary observer and so the sound will appear to have shorter wavelength. This creates an effect of its siren to sound with higher frequency than it would do if both were stationary.

(7) The Doppler formula for frequency in the case of a stationary observer and source approaching it is as follows:

$f_O = \frac{v}{v-v_s}\cdot f= \frac{343\frac{m}{s}}{(343-25)\frac{m}{s}}\cdot 400Hz \approx 431Hz$

The wavelength is then

$\lambda = \frac{343\frac{m}{s}}{431Hz}\approx 0.80 m$

The third choice "0.80m; 431Hz" is correct

An average man is 80 k (800 N) and the area of the shoes he is wearing is 0.0092 m2. What is the pressure he is exerting on the

S_A_V [24]

Answer:

P = 86956.52 Pa

Explanation:

Data:

F = 800 N
A = 0.0092 m²
P = ?

Use the formula:

$\boxed{\bold{P=\frac{F}{A}}}$

Replace and solve:

$\boxed{\bold{P=\frac{800\ N}{0.0092\ m^{2}}}}$

$\boxed{\bold{P=86956.52\ Pa}}}$

The pressure it exerts on the ground is <u>86956.52 Pascal.</u>

Examples of fixed pulley?

Neko [114]

Answer:

One example of a fixed pulley is a Flag Pole

Explanation:

A good example of a fixed pulley is a flag pole: When you pull down on the rope, the direction of force is redirected by the pulley, and you raise the flag. Other examples of movable pulleys include construction cranes, modern elevators, and some types of weight lifting machines at the gym.
