Heya!!!
Answer to your question:
C.
Energy transferred to a machine equals energy transferred from it.
Law of conservation of energy states that total energy of an isolated system remains constant
Energy can neither be created nor be destroyed. Machine follows the same rule.
Hope it helps ^_^
Answer:
6.060606...
Explanation:
To figure out velocity, you divide the distance by the time it takes to travel that same distance, then you add your direction to it. So the distance would be 1000m and the time would be 2 minutes and 45 seconds and if you convert the minutes into fractions you would get 165 seconds than you would divide 1000m by 165 seconds and you would get 6.060606... seconds as her average velocity
Answer:
0
Explanation:
Suppose this is for Excel. You can hide a row or a column by right-clicking on that row/column header and select row height or column width. After that simply input in 0 and click OK. The row or column will be hidden in the end, just like using a Hide command.
Answer:
76.9 m/s
Explanation:
total distance travelled is 750m + 250m = 1000m
the total time taken is 13 seconds.
1000m/13s = 76.9 m/s (1dp)
Explanation:
This problem seeks to ensure that the student comprehends the meaning of precision and accuracy.
These two key terms are used to express how reliable experimental values obtained are.
- Precision is the ability to consistently reproduce a result.
- Accuracy is the nearness of the measure value to the true value.
- The different between the measured and true values gives the error in the result.
In the problem given, the most accurate reading would be one that has value close to the standard mass of 150g. Any student that reports this value would be reported as accurate.
The precise reading would be for the student that is able to repeatedly produce the same kind of values. This is irrespective of whether the values are close to the true value or not.
