c) 1610 s

d) 0.0890 m

Explanation:

Significant figures:

The given measurement have four significant figures 1234.

All non-zero digits are consider significant figures like 1, 2, 3, 4, 5, 6, 7, 8, 9.

Leading zeros are not consider as a significant figures. e.g. 0.03 in this number only one significant figure present which is 3.

Zero between the non zero digits are consider significant like 104 consist of three significant figures.

The zeros at the right side when decimal point is present e.g 2400. are also significant. There are four significant figures are present.

a) 0.003 L

This measurement have 1 significant figure which is 3.

b) 140 g

This measurement have 3 significant figure  1, 4. In this measurement 0 is trailing zero that's why it is not consider significant.

c) 1610 s

This measurement have 3 significant figures 1, 6, 1.

d) 0.0890 m

This measurement have 3 significant figures 8,9 and 0

Answer: C

Explanation:

Answer:

Microwaves

Explanation:

Microwaves have more energy than blue light

Among microwaves or blue light, blue light has a higher frequency. This is because blue light belongs to the visible region has a short wavelength and produces a higher amount of energy.

The frequency of any wave is inversely related to the wavelength. This means that when the frequency of the wave increases, the wavelength decreases. While the relationship between frequency is directly related to the energy.

According to the context of this question, gamma rays have the highest frequency and shorter wavelength, while radiowaves have a shorter frequency and the highest wavelength.

Therefore, blue light has a higher frequency. This is because blue light belongs to the visible region has a short wavelength and produces a higher amount of energy.

Answer:

One type of evidence that strongly supported the Theory of Continental Drift is the fossil record. Fossils of similar types of plants and animals in rocks of a similar age have been found on the shores of different continents, suggesting that the continents were once joined.

Explanation:

Students were asked to describe evidence of Plate Tectonic Theory.

descriptions listed above accurately describe evidence supporting Plate

Tectonic Theory. Student 3 describes "glacial evidence indicates that different continents were once connected near the South Pole."

The widely recognized scientific hypothesis known as plate tectonics states that the Earth's lithosphere was made up of many major tectonic plates that have already been gently migrating since around 3.4 billion years ago.

The south pole would be one of two locations on Earth's surface at which the planet's axis of rotation crosses it. It is often referred to as one of the Geographic south pole, Terrestrial South Pole, and 90th Parallel South.

The fossil record is such sort of evidence that has been used to support the Claim of Continental Drift. On the coastlines of many continents, fossils of specific kinds of plants, as well as animals have been discovered in rocks that are comparable in age, indicating that the continents had been connected.

Answer:

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

[tex]n = \frac{N}{L} \\[/tex]

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

[tex]n = \frac{6.34 \times {10}^{22} }{6.02 \times {10}^{23} } \\ = 0.105315...[/tex]

Explanation:

Without photosynthesis there would be no oxygen in the earth's atmosphere and we wouldn't be here!

Answer:

Mass = 234 g

Explanation:

Given data:

Mass of NaCl produced = ?

Moles of chlorine = 2.0 mol

Solution:

Chemical equation:

2Na + Cl₂    →     2NaCl

now we will compare the moles of NaCl with chlorine gas.

           Cl₂           :          NaCl

             1            :           2

            2.0         :         2/1×2.0 = 4.0 mol

Mass of NaCl;

Mass = number of moles × molar mass

Mass = 4.0 mol × 58.5 g/mol

Mass = 234 g
