Answer:
4%
Step-by-step explanation:
Actual length of wire = 5 cm
The measured length of wire = 5.2 cm
We need to find the percent error in the measurement of the length of wire. It can be calculated as follows :

So, the required percent error is 4%.
Step-by-step explanation:
Area of rectangle =L×W
Width =Area

sin(45°) = (2/4) = (1/2) = sqrt{1/2} = sqrt{1}/sqrt{2} = 1/sqrt{2}.
Answer: 1/sqrt{2}
Answer:1.72Gal
Step-by-step explanation:1 Gal is 3.785 L. 6.5 / 3.785 = 1.72
The reaction times form a straight line with gradient of 60/140 = 3/7 m/kph
Reaction time at 130 kph = 3/7 x 130 = 390/7 = 56 m to nearest whole number
