Answer: Precision means that measurements are close to each other . Accuracy means that measurements are close to accepted value
Explanation:
Precision refers to the closeness of two or more measurements to each other.
For Example: If we weigh a given substance five times and you get 5.0 kg each time. Then the measurement is very precise.
Accuracy refers to the closeness of a measured value to a standard or known value.
For Example: If the mass of a substance is 5.0 kg and one person weighed 4.9 kg and another person weighed 3.9 kg. Then, the weight measured by first person is more accurate.
Thus Precision means that measurements are close to each other . Accuracy means that measurements are close to accepted value.
Halides is the term given to the ions of halogens. Halogens are the second-to-the-last column or period in the periodic table. Examples are chlorine, fluorine, bromine and iodine. Halides are all soluble in water except when combine with silver, lead and mercury. <em>Therefore, the generalization we can make is that silver halides are insoluble in water,</em>
Answer:
Therefore F ∠ 2.5N
Explanation:
Definition of Work:
It is the amount of energy transferred.
Mathematical expression:
W = F × d
By taking the friction into count it will define as:
Input work = work against friction × output work
No we will put the values:
25 J = w + 10 m
j = kg m²/s²
25 kg m²/s² = w + 10 m
when friction is exist then w > 0
25 kg m²/s² - 10 m > 0
15 N > 0
Therefore F ∠ 2.5N
