The struggles were that women weren't really supposed to get an education back then, people called intelligent women witches and wouldn't teach them things. Those were the main struggles.

  After giving an intense performance, a confused and disoriented flautist has wandered onto the motorway! They are playing a con
leva [86]
This is a Doppler effect. Generally, if you move to a frequency source, you would detect an increase in frequency and when you move away from a source you would detect a decrease.

For this question, before you pass them, you are actually approaching them, so you would hear a higher frequency than the constant 300 Hz they are playing at.

Using the condensed formula:

 f '   =   ((v <u>+</u> vd)/(v <u>+</u> vs)) * f

Where:  vd = Velocity of the detector.
              vs = Velocity of the frequency source.
              v   =  Velocity of sound in air.
              f '  =  Apparent frequency.
              f    =  Frequency of source.

v = 343 m/s,  vd = detector = 27.8 m/s,  vs = velocity of the source =0. (the flautists are not moving).
f = 300 Hz. 

There would be an overall increase in frequency, so we maintain a plus at the numerator and a minus at the denominator.

 f '   =   ((v + vd)/(v - vs)) * f

f '   =   ((343+ 27.8)/(343 - 0)) * 300
      =   (370.8/343)* 300 =  324.3

Therefore frequency before passing them = 324.3 Hz.

Cheers.

His eyes are 1.76 m above the floor, and the top of his head is 0.15 m higher. Find the height (in m) above the floor of the top
krek1111 [17]

Answer:

The height (in m) above the floor of the top and bottom of the smallest mirror in which he can see both the top of his head and his feet is;

1.835 m and 0.88 m.

Explanation:

Here we have the total height of the man as

1.76 + 0.15 = 1.91 m

The mirror is positioned such that the person can see both the top of his head and his feet

We have the eyes are 0.15 m below the top of the head, therefore by the law of reflection, the incident and reflected angle must be equal.

Hence, the light from the top of his head and then reflected to his eyes forms a isosceles triangle, with the base being the distance of the eye to the top of his head and the top of the triangle is on the mirror.

The height of the mirror is then

1.91 - 0.15/2 = 1.835 m

Similarly, the distance from the eye to the feet is 1.76, therefore, the base of the mirror is positioned at 1.76/2 or 0.88 m above the ground.

Which part of a tidal power plant is the tidal water pushed through to generate electricity? barrage boat dam turbine
madam [21]

Answer:

turbine

Explanation:

Tidal energy is produced in the Tidal power plant to produce electricity. The kinetic energy is produced because of the energy of the tides in the form of moving water. This energy is converted into electricity with the help of power turbines. The turbine plays an important role in the production of electricity. The fluid that is used in the turbine contains potential energy. The moving turbine converts the potential energy to kinetic energy and the energy is collected in the form of electricity.
