What is the formula for atmospheric pressure.

A string of length 0.67 m and mass 2.0 g is held at both ends under tension. The string

ikadub [295]

Answer:

The value is $\lambda = 0.335 \ m$

Explanation:

From the question we are told that

The length of the string is $l = 0.67 \ m$

The mass is $m = 2.0 \ g = 0.002 \ kg$

The frequency produced at fourth harmonic vibration(i.e n =4 ) is $f = 700 \ Hz$

Generally the wavelength of the string is mathematically represented as

$\lambda = \frac{ 2L }{n }$

=> $\lambda = \frac{ 2 * 0.67 }{ 4 }$

=> $\lambda = 0.335 \ m$

If the electron just misses the upper plate as it emerges from the field, find the speed of the electron as it emerges from the

Scilla [17]

The speed of the electron as it emerges from the field is; 388.587 m/s

<h3>What is the speed of the electron?</h3>

Initial speed; v₀x = 1.1 * 10⁶ m/s

Acceleration in horizontal direction = 0 m/s²

distance; s_x = 2 cm = 0.02 m

Thus, formula to find time here is;

t = s_x/v₀x

t = 0.02/(1.1 * 10⁶)

t = 1.82 * 10⁻⁶ s

Now for the vertical distance; v,y_o = 0 m/s

Thus, the equation of motion becomes;

s_y = ¹/₂at²

0.005 = ¹/₂a(1.82 * 10⁻⁶)²

Solving for a gives;

a = 3.02 * 10¹³ m/s²

Thus the speed of the electron as it emerges from the field is;

v² = u² + 2as

v = √(0² + 2(3.02 * 10¹³ * 0.005))

v = 388.587 m/s

Complete Question is;

An electron is projected with an initial speed v0 = 1.1 * 10⁶ m/s into the uniform field between the parallel plates. The distance between the plates is 1 cm and the length of the plates is 2 cm. Assume that the field between the plates is uniform and directed vertically downward, and that the field outside the plates is zero. The electron enters the field at a point midway between the plates. E = N/C

find the speed of the electron as it emerges from the field?.

3. Suppose that you have an electrically charged stick. If you divide the stick in half, each half will have half the original c

FrozenT [24]

Answer:

No, you can't keep on dividing the charge forever.

Explanation:

No, you can't keep on dividing the charge in that manner forever because the total charge of the stick is an integer multiples of individual units known as an elementary charge, <em>which is the electron (e) charge (e = 1.602x10⁻¹⁹C)</em>.

Therefore the limit of the division of the original charge will be the electron charge since it is the smallest charge that can exist freely.

I hope it helps you!
