Answer:
B. Identifying the types of data to be gathered
Explanation:
Identifying the types of data to be gathered is one of the part of designing a set of experimental procedure.
An experimental procedure is a methodical process that must be followed in order to attain the goal of the experiment.
- As with most experiments, data is collected for further analysis and interpretation.
- The choice of way of collecting data and the type of data to be collected is very important when designing an experiment.
Answer:
0.5 m/s north
Explanation:
Take east to be +x, west to be -x, north to be +y, and south to be -y.
His displacement in the x direction is:
x = 20 m − 20 m = 0 m
His displacement in the y direction is:
y = 10 m
His total displacement is therefore 10 m north.
His velocity is equal to displacement divided by time.
v = 10 m north / 20 s
v = 0.5 m/s north
Answer:
Efficiency
Explanation:
- The amount of mechanical work an engine can do per unit of heat energy it uses is called its efficiency.
- It is also defined as the output divided by the total electrical power consumed.
- In terms of heat, efficiency of engine is given by :

are output heat and input heat respectively.
Hence, the correct option is (d) "efficiency"

Hey kid!
So let’s not make this complicated. Obviously this word problem is wanting to confuse you with all these fancy words but, we’re not letting that get in the way!
Our two numbers are 6 and 12. If you think about it... 12 divided by 6 equals 2!!
That would make your answer B) 2m.
Happy to help!
