Answer:
graph 1
Explanation:
acceleration is defined as change in velocity/ change in time.
A constant acceleration should have a linear line.
Since velocity is in the numerator of the formula it is the dependent variable which will go on the y axis. thus making time the independent going on the x axis.
This makes sense because velocity should depend on time not the other way around. This therefore making the right answer graph 1
Answer:
0.75%
Explanation:
Measured value of melting point of potassium thiocyanate = 174.5 °C
Actual value of melting point of potassium thiocyanate = 173.2 °C
<em>Error in the reading = |Experimental value - Theoretical value|</em>
<em>= |174.5 - 173.2|</em>
<em>= |1.3|</em>
<em>Percentage error = (Error / Theoretical value) × 100</em>
<em>= (1.3 / 173.2)×100</em>
<em>= 0.75 %</em>
∴ Percentage error in the reading is 0.75%
