Answer:
The chemical is the same but the concentration is different.
The chemical is more dangerous in its highly concentrated form.
Although the chemicals are the same, they require different handling procedures. Therefore specific information should be available for each.
Explanation:
Calculate the amount of time it takes to heat the water by dividing the power used to heat the water, which was determined to be 1.867 with the heater element rating, listed in kW. So if your heater element rating was 3.6 kW, your equation would look like this: heating time = 1.867 ÷ 3.6, or heating time =0.52 hours.
Wave motion is the transfer of energy and momentum from one point of the medium to another point of the medium without actual transport of matter between two points.The dimensions in which a wave propagates energy, The energy transfer
Answer: The mean value <u>= 9.85m/s².</u>
Explanation:
Mean =
The given measurements the acceleration of gravity (units of m/s²): 10.1, 9.87, 9.76, 9.91, 9.75, 9.88, 9.69, 9.83, and 9.90.
Number of measurements =9
Sum of measurements = 88.69
Mean =
Hence, the mean value<u> = 9.85m/s².</u>
