GivenHorizontal velocity, vxi = 1.5 *10^6 m/sDistance ,x =0.35 mFirst we will calculate the time takenx = vxi t0.35 m = (1.5 *10^6 m/s) tt =0.23 *10^-6 sThe vertical distance travelled by the electron isy =1/2 gt^2= 0.5 *9.8 m/s^2 *(0.23 *10^-6 s)^2= 0.25 *10^-12 m

Therefore, the answer is 0.25 *10^-12 m

A sample of 0.2140 g of an unknown monoprotic acid was dissolved in 25.0 mL of water and titrated with 0.0950MNaOH. The acid req
bezimeni [28]

in a monoprotic acid , its capable of dissociating 1 H⁺ ion . The base used is NaOH which is capable of giving out 1 OH⁻ ion.

Therefore both base and acid react in a 1:1 molar ratio, that means for each 1 mol of monoprotic acid there is , it requires 1 mol of NaOH to be neutralised.

So at equivalence point the number of acid moles present should react with an equal number of NaOH moles to be neutralised

number of NaOH moles added - concentration x volume

number of NaOH moles - 0.0950 mol/dm³ x 27.4 x 10⁻³ dm³ = 0.00260 mol

since molar ratio of NaOH to Acid is 1:1

number of acid moles present is also - 0.00260 mol

mass of acid added - 0.2140 g

we can find molar mass using following equation

molar mass = mass / number of moles

molar mass = 0.2140 g / 0.00260 mol = 82.3 g/mol

therefore molar mass of monoprotic acid is 82.3 g/mol

Wind blowing across suspended power lines may
Flura [38]

Answer: (4) Resonance

Explanation:

Resonance is a phenomenon in which an external force or a vibrating system forces another system around it to vibrate with greater amplitude at a specified frequency of operation.

Some Examples of Resonance

Musical Instruments

The best examples of resonance can be observed in various musical instruments around us. Whenever any person hits, strikes, strums, drums or tweaks any musical instrument, the instrument is set into oscillation or vibration at the natural frequency of vibration of the instrument. A unique standing wave pattern defines each frequency of vibration as a specific instrument. These natural frequencies of a musical instrument are known as the harmonics of the specified instrument. If a second interconnected object or instrument vibrates or oscillates at that specified frequency then the first object can be forced to vibrate at a frequency higher than its natural harmonic frequency and as such, resonance occurs.

Aoelian Vibration (Harp)

Wind blowing across suspended power lines may cause the power lines to vibrate at their natural frequency. This often produces audible sound waves showing that resonance has occurred due to the frequency of vibration of the wire coninciding with that of the wind.
