Option (B) is correct.Energy contained in one gram of matter=9 x 10¹³ J
Explanation:
mass= 1 g= 0.001 kg
c= velocity of light= 3 x 10⁸ m/s
The mass energy equivalence equation is given by
E = m C²
E= (0.001)(3 x 10⁸)²
E=9 x 10¹³ J
Thus energy contained in one gram of matter=9 x 10¹³ J
If you were able to unstrand each piece of DNA, you would see differences in time which would be labeled as "evolution"
Average speed = (total distance covered) / (time to cover the distance)
Total distance = 69 km + 51 km = 120 km
Total time = 3 hrs + 2 hrs = 5 hrs
Average speed = (120 km) / (5 hrs) = 24 km/hr
Answer:
“Measurement” is the act of determining a target's size, length, weight, capacity, or other aspect. There are a number of terms similar to “measure” but which vary according to the purpose (such as “weight,” “calculate,” and “quantify.”) In general, measurement can be understood as one action within the term “instrumentation.”
Explanation:
• To show measured results using values and symbols. • To use measurement tools.
Measuring a target can be done through either direct measurement or indirect measurement. An Indirect measurement is done, for example, by using a dial gauge to measure the height difference between a measurement target and a gauge block and using that height to indirectly determine the target's height. Because this type of measurement is based on a reference, indirect measurement is also referred to as “comparative measurement.
An ”Direct measurement is measurement done by bringing the target into contact with the measurement system to read the length, height, or other aspect directly. Although direct measurement allows measurement results to be known as they are, errors may occur depending on the skill of the person doing the measurement.
Answer: The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat.
