Most ejections originate from active regions on the Sun's surface, such as groupings of sunspots associated with frequent flares. These regions have closed magnetic field lines, in which the magnetic field strength is large enough to contain the plasma.

Why is it necessary to centrifuge out any precipitate formed in the unknown solution and continue testing the remaining unknown
jonny [76]

Answer:

Precipitation is the formation of a solid from a solution. It is necessary to centrifuge the precipitate to exert sufficient forces of gravity to bring the solid particles in the solution to come together and settle

Explanation:

When you centrifuge precipitate it enables the nucleation to form.

Centrifuging the precipitate helps in determining whether a certain element is present in a solution or not.

f a wave has a wavelength of 9 meters and a period of 0.006, what is the velocity of the wave? A. 1,200 m/s B. 1,500 m/s C. 1,80
GalinKa [24]

Answer: 1500 m/sec. ( b )

Solution:

V= f (λ)

Speed = frequency. Wavelength  

And frequency = 1/time period

First we will find the frequency :

Frequency = 1/time period

1/0.006 = 166.67 Hz

Using this in the equation:

Speed = frequency. Wavelength  

V= f (λ)

9 × 166.67  

= 1500.03 ≈ 1500

V (Speed) = 1500 m/s.

Note: Do not forget to mention the units or otherwise they may cost you marks!

A simple harmonic transverse wave is propagating along a string towards the left direction as shown in the figure. figure shows
dimulka [17.4K]

Answer:

  1. Amplitude  = 5 cm (Heights)
  2. Wavelength (λ)  = 40 cm
  3. Wave speed (v) = 12 m/s (Approx)
  4. Time period (T) = 0.033 s (Approx)
  5. Maximum particle speed (V) = 9.43 m/s

Explanation:

1) Amplitude

Amplitude  = 5 cm (Heights)

2) Wavelength (λ)

Wavelength (λ)  = 40 cm

3) Wave speed

Wave speed (v) = √ t / μ

Wave speed (v) = √ 3.6 / [25x10⁻³]

Wave speed (v) = 12 m/s (Approx)

4) Time period (T)

Time period (T) = 1/f = (λ)/v

Time period (T) = 0.40m / 12

Time period (T) = 0.033 s (Approx)

5) Maximum particle speed (V)

Maximum particle speed (V) = Aw

Maximum particle speed (V) = [0.05x2x3.14] / 0.033

Maximum particle speed (V) = 9.43 m/s
