Answer:
there I think the answer is measuring tape we cannot use a metre rule because it measures straight lines and I think measuring tape is better because it is flexible thus makes measurement easier

Answer:
The magnitude of Resultant force is F = 7.21-lbs
Explanation:
Two forces acting on an object which are named as F1 and F2.
The angle formed by the forces are 60-degrees
F1 = 6-lbs , F2 = 8-lbs
theeta = 60°
F = √F1²+F2²-2(F1)(F2)cos(theeta)
F = √(6)²+(8)²-2(6)(8)cos(60)
F = √36+64-(96)cos(60)
F = 7.21-lbs
where,
F1 = magnitude of force 1
F2 = magnitude of force 2
theeta = angle formed by forces
'First Quarter' is the phase that appears one quarter of the
period of time from one new moon to the next one.
The total period of the moon's phases is 29.53 days (rounded).
One quarter of it is (29.53 / 4) = <em>7 days 9.2 hours</em> (rounded)
Because it is not a good conductor of heat. so the answer is D.
