If the frequency of the 13C signal of TMS is 201.16 MHz, the two 13C signals of acetic acid at 179.0 and 20.0 ppm are separated
Lelu [443]

The difference in frequency of the two signals is 1.33 \times 10^{10} \ kHz.

The given parameters;

  • <em>frequency of the 13 C signal = 201.16 MHz</em>

The energy of the 13 C signal located at 20 ppm is calculated as follows;

E = hf\\\\E_1 = h \frac{c}{\lambda} \\\\E_1 =  \frac{(6.626 \times 10^{-34})\times 3\times 10^8}{20 \times 10^{-6}} \\\\E_1 = 9.94 \times 10^{-21} \ J

The energy of the 13 C signal located at 179 ppm is calculated as follows;

E_2 = \frac{hc}{\lambda} \\\\E_2 = \frac{(6.626\times 10^{-34})\times (3\times 10^{8})}{179 \times 10^{-6} } \\\\E_2 = 1.11 \times 10^{-21} \ J

The difference in frequency of the two signals is calculated as follows;

E_1- E_2 = hf_1 - hf_2\\\\E_1 - E_2 = h(f_1 - f_2)\\\\f_1 - f_2 = \frac{E_1 - E_2 }{h} \\\\f_1 - f_2 = \frac{(9.94\times 10^{-21}) - (1.11 \times 10^{-21})}{6.626\times 10^{-34}} \\\\f_1 - f_2 = 1.33 \times 10^{13} \ Hz\\\\f_1 - f_2 = 1.33\times 10^{10} \ kHz

Thus, the difference in frequency of the two signals is 1.33 \times 10^{10} \ kHz.

B) purchasing network time for

C) creating infomercials for

D) sponsoring

E) advertising

The correct answer is D) sponsoring .

Explanation:

Sponsorship is an advertising strategy that consists of an organization (sponsor) committing to provide financing to a third party (sponsored) in exchange for the presentation of its brand or product.

The sponsorship consists of an agreement or agreement between two people (legal or physical) in which, one of the parties called sponsor, will deliver a consideration (monetary or material) to another sponsored call, so that the latter exposes its brand or product publicly.

Sponsorship Objective

Sponsorship is a subtle form of advertising where the company seeks that customers associate their brand with an activity or person that represents values ​​or qualities that attract their customers. These activities or people are usually outside the scope of the normal activity of the company, for example: a prestigious event, an admired athlete or the celebration of a relevant event, etc.

The ultimate goal of sponsorship is to attract customers and increase sales.
