Answer:
408.33watts
Explanation:
Power is expressed according to the formula
Power = work done/time
Power = force × distance/time
Power = Force× velocity
Find the force
F = mv/t
F = 600×1.75/4.5
F = 1050/4.5
F=233.33N
Get the power
Power = 233.33×1.75
Power = 408.33watts
Hence the average power of the elevator motor during this period is 408.33m/s
Temperature and pressure are directly proportional to each other. If this helps,please pick me the best. Also,please say thanks.
Explanation:
measurement of a set, accuracy is closeness of the measurements to a specific value, while precision is the closeness of the measurements to each other.
Accuracy has two definitions:
More commonly, it is a description of systematic errors, a measure of statistical bias; low accuracy causes a difference between a result and a "true" value. ISO calls this trueness.
Alternatively, ISO defines[1] accuracy as describing a combination of both types of observational error above (random and systematic), so high accuracy requires both high precision and high trueness.
Precision is a description of random errors, a measure of statistical variability.
In simpler terms, given a set of data points from repeated measurements of the same quantity, the set can be said to be accurate if their average is close to the true value of the quantity being measured, while the set can be said to be precise if the values are close to each other. In the first, more common definition of "accuracy" above, the two concepts are independent of each other, so a particular set of data can be said to be either accurate, or precise, or both, or neither.
First, volcanic eruptions produce major quantities of carbon dioxide (CO2), a gas known to contribute to the greenhouse effect. ... The small ash particles decrease the amount of sunlight reaching the surface of the earth and lower average global temperatures.
... low frequency and high amplitude.
