evablogger [386]

Answer:

3) 0.75m/s

Explanation:

The wavelength of a wave is calculated using the formula;

λ = v/f

Where!

λ = wavelength of wave (m)

v = velocity or speed (m/s)

f = frequency of wave (Hz)

According to this question, one end of a rope is vibrated to produce a wave with a wavelength (λ) of 0.25 m and frequency (f) of 3.0 Hz.

Using λ = v/f

v = λ × f

v = 0.25 × 3

v = 0.75m/s.

Photo 51 is a picture of the structure of DNA that was used to create a model of DNA. Who created the photo?
Aleksandr-060686 [28]
<span>DNA stands for deoxyribonucleic acid. It has a double strand that contains the genes (a hereditary material) of the organism. It was discovered by James Watson and Francis Crick. Their double-helix structure was based on x-ray diffraction image named as Photograph 51 or Photo 51. It was taken by Raymond Gosling, a pHD student under the supervision of Rosalind Franklin. They used this photo to determine the chemical and physical structure of the DNA and the bond that links the genes altogether. The answer is Rosalind Franklin</span>
