From the atomic clock that utilizes C-133 which has an approximate frequency of 9.193 x 109 Hz. The wavelength of the energy is calculated to be 0.0326m.

From the given information:

The frequency f = 9.193 × 10⁹ Hz = 9.193 × 10⁹ 1/s
The wave speed c = 3.00 × 10⁸ m/s

Recall that:

The wavelength is the spatial successive distance between two crests of a wave and can be expressed by the formula:

$\mathbf{\lambda = \dfrac{c}{f}}$

$\mathbf{\lambda = \dfrac{3.00 \times 10^8 \ m/s }{9.193 \times 10^9 \ 1/s}}$

$\mathbf{\lambda =0.0326 \ m}$

Therefore, we can conclude that the wavelength of the atomic clock is 0.0326m. As such Option D is correct.

39. Analyze What subscripts would you most likely use if

Igoryamba

Based on their valencies, the subscripts of the ionic compounds formed will be:

1 and 1
2 and 1
1 and 2
2 and 2

<h3>What subscripts would you most likely use if the following substances formed an ionic compound?</h3>

A. An alkali metal and a halogen.

An alkali metal and a halogen both have valencies of one.

Therefore the subscripts would be 1.

B. An alkali metal and a non-metal from group 16.

An alkali metal has a valency of 1 and a group 16 non-metal has a valency of 2.

By exchange of valencies, the subscript would be 2 and 1.

C. An alkaline earth metal and a halogen.

An alkaline earth metal has a valency of 2 and a halogen has a valency of 1.

By exchange of valencies, the subscripts would be 1 and 2.

D. An alkaline earth metal and a non-metal from group 16.

An alkaline earth metal has a valency of 2 and a non-metal from group 16 has a valency of 2.

By exchange of valencies, the subscripts would be 2 and 2.

Therefore, the subscripts of the ionic compounds formed will be:

1 and 1
2 and 1
1 and 2
2 and 2

Scientist have genetically altered a common virus so that it can Destroy the most lethal type of brain tumor without harming the

sergey [27]

Answer:

The correct answer is - discovering or diagnosing the disease.

Explanation:

According to the question, this technology includes genetically modifying a common virus in order to destroy or kill the deadly brain tumor without affecting normal cells around the tumor, this technique is genetic engineering.

This technique can help in treating or curing the disease by killing the tumor cells and make them non-lethal. It can also prevent the tumor cells to grow and make them controlled. There is nothing mention related to diagnosing the disease in the question and it is not possible to find this tumor with help of such a technique.

The cells of a tomato contain mostly an aqueous solution of sugar and other substances. If a typical tomato freezes at -2.5 °C,

DIA [1.3K]

Answer:

1.35 m

Explanation:

We can solve this problem by using the freezing point depression formula:

ΔT = Kf * m * i

Where:

ΔT is the temperature difference between the freezing point of the pure solvent (water) and the solution. In this case it is (0 °C - -2.5 °C = 2.5 °C).

Kf is the cryoscopic constant, for water it is 1.853 °C*kg/mol.

m is the molality.

i is the van't Hoff factor, as sugar does not dissociate in water, it has a value of 1.

We input the data:

2.5 °C = 1.853 °C*kg/mol * m * 1

And solve for m:

m = 1.35 m
