- A copper wire of diameter 1.2 cm stretches 0.02% when it is used to lift a load upward with an acceleration of 2.1 m/s². What is the weight of the load (in kN)? X KN 217.945 +Calculate the force (in N) a piano tuner applies to stretch a steel piano wire 8.10 mm, if the wire is originally 0.850 mm in diameter and 1.35 m long.relative to the space available. Calculate the magnitude (in N/m²) of the normal force per square meter exerted by the juice if its bulk modulus is 1.6 × 10⁹ N/m², assuming the bottle does not break. A farmer making grape juice fills a glass bottle to the brim and caps it tightly. The juice expands more than the glass when it warms up, in such a way that the volume AV increases by 0.3% (that is, = 3 x 10-3 V N/m² In view of your answer, do you think the bottle will survive? (Hint: How many atmospheres is this?) O Yes O No
