Known result = 16.100 g
For a measurement of x g, the % error is calculated s
Create a table that calculates the %error for each measurement
x %error
---------- ---------
16.009 0.565
15.780 1.988
16.110 0.062
15.990 0.683
From the calculated results, it s clear that the measurement of 16.110 g has the least error, and it is, therefore, the most accurate.
Answer:
The most accurate measurement is 16.110 g.
Answer:
22.47 %
Explanation:
v 1 = 328 m/s, v 2 = 363 m/s
We know that the velocity of a wave in a stretch string is directly proportional to the square root of the tension in the string.
Percentage increase in the tension
= \left ( \frac{1}{0.8165}-1 \right )\times 100
= 22.47 %
Answer:
Explanation:
Heat generated by the coil is expressed as;
Heat generated = Power ×Time
Heat generated = IVt
I is the current = 4A
V is the voltage= 5V
t is the time = 4hrs
Convert to secs
t = 4(3600) = 14400secs
Substitute into the formula
Heat generated = 4×5×14400
Heat generated = 20×14400
Heat generated = 288000Joules
Heat generated =288KJ
