Thermometer D, because it measures accurately to the tens place. Hence, option B is correct.
<h3>What is temperature?</h3>
The degree of hotness or coldness is measured on a definite scale.
Accuracy: It is defined as the closeness of a measured value to a standard or known value.
For Example: If the mass of a substance is 50 kg and one person weighed 48 kg and another person weighed 55 kg. Then, the weight measured by the first person is more accurate.
Precision: It is defined as the closeness of two or more measurements to each other.
For Example: If you weigh a given substance five times and you get 1.8 kg each time. Then the measurement is said to be precise.
The level of precision is determined by the maximum number of decimal places.
As per the question, the thermometer D has markings 40°, 45° and 50° at equal intervals and there are four small markings equally spaced in between the numbers and thermometer D has markings 40°, 45° and 50° at equal intervals but there are no small markings equally spaced in between the numbers. That means thermometer D measures temperature more accurately than thermometer C.
Thermometer D, because it measures accurately to the tens place. Hence, option B is correct.

Answer:
Explanation:
From the work of Krogh in 1918 until the present time, a very wide range of values for oxygen diffusion coefficients has been reported1–5 ranging from 1.1 × 10−4 to 4 × 10−8 cm2 sec−1.
Metals have their valence band filled, and due to the absence of a band gap, their conduction band partially filled.
The theory predicts that metals will conduct (both heat and) electricity very well and so is generally accepted.
The 15th Amendment to the Constitution granted African American men the right to vote by declaring that the "right of citizens of the United States to vote shall not be denied or abridged by the United States or by any state on account of race, color, or previous condition of servitude."
There are two kinds of mixtures
a) homogeneous : the boundary of the two components is not physically distinct
b) heterogeneous:the boundary of the two components is physically distinct
the following separation techniques are common for mixtures
1) filtration: if the two components are forming heterogeneous mixture we can separate them by filtration.
2) boiling: if boiling point of one of the components is less than other
3) magnetic separation: if one of the component is magnetic
4)sieve method: for solid components with difference in size of particles
5) hand picking
Thus the correct match will be as shown in the figure
