<u>Answer</u>
C. 0.6125 m
<u>Explanation</u>
The magnification of an image produced by curved mirrors can be given in two ways;
Magnification, M = (Height of the image) / (height if the object) and
M = (image distance,V) / (Object distance, U).
Using the first formula,
M = 0.35/0.4
= 0.875
Now from the second formula,
M = V/U
0.875 = V/0.7
V = 0.875 × 0.7
= 0.6125 m
It is a synthesis reaction where two reactants gives one product.
Answer:option D
2Mg + O2 ------> 2 MgO
Answer:
<em>The second option has a lower power output. P=30 W</em>
Explanation:
<u>Mechanical Power
</u>
It is a physical magnitude that measures the rate a work W is done over time t.
Since W=F.d
The first option means the worker will lift the box by a distance of 1.2 meters in 3 seconds by applying 250 N of force. That produces a power of
The second option requires the worker applies 75 N of force and travel a distance of 4 meters for 10 seconds, thus the power is
The second option has a lower power output
Daltons, a unit of molecular weight, are used to measure protein size. The mass of a hydrogen atom, which is 1.66 x 10-24 grammes, is considered to be one Dalton. Since the majority of proteins have masses in the thousands of Dalton range, the term kilodalton (kDa) is frequently used to refer to the molecular weight of proteins.
- Daltons (Da) or kilodaltons, which are units of molecular weight, are typically used to measure proteins (kDa). By comparing the sizes of standard molecular weight markers of known size that were run in parallel with the unknown samples during gel electrophoresis, one can estimate the sizes of DNA, RNA, or protein molecules that were separated on gels.
- Different techniques have been used to assess the electrophoretic mobilities of DNA polymer fragments in an agarose gel and then convert those measurements to lengths using the reciprocal method. The length estimations can be greatly distorted by the measurement technique.
