A teacher divides her class into groups and assigns each group the task of measuring the length of the same object three times. The teacher already knows that the length of the object is 78.5 mm. Based on the results the students record, which group makes the most accurate measurements of the object? A. Group D: 75.0 mm, 75.0 mm, 75.0 mm B. Group B: 75.5 mm, 75.0 mm, 74.8 mm C. Group C: 78.5 mm, 72.9 mm, 79.8 mm D. Group A: 78.5 mm, 77.5 mm, 79.5 mm

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.

explanation:

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6
