Question

Location Fluid Earth Fresh Water Bottle Mass 1000 g Bottle Volume 500 mL 000 Reset

Weight of the bottle= 1000g (1 Kg)

Volume in the bottle= 500ml

Gradually,The bottle is immersed in the freshwater

Questions :

1. Assume the freshwater density is 1000 kg/m³, calculate the weight of the displaced fluid?

2. What is the Buoyancy force on the bottle?

3. Derive an equation to find the density of the object in terms of weight of the object, apparent weight of the object, and the volume of the object?

Answer 1

1. the liquid displaced weight of Wed veg V = volume of bottle 50ome e = density of liamid - 1000 kg/m3 500x106 m² ga acceleration due to gravity = 10 m/s² Wed 500x10-6 x 1000 x 10 N. 5 N. weight of displacend -5N. weight of bottle th'= 0 mg a 1810=10N. here than Wed. greater so buoyant force FB-W-wed = 10-5 =5N. - W. Buoyant force = 5N. Density of object (bottole) =D weight of object Apparent weight WA = weight of object weight of displaced liquid. weight of liquid displaced W W Density of object of object Density of florid weight of liquid displaced WA Weight -

D W W-WA e P. ew density of fluid => D W-WA An W-WA= eur D W-WA. weight of liquid displaced= veg N= volume of object, e-density of lignid. e = (W-WA) vg D = (W-WA). W vg W-WA W-WA w W-WA. D - Density of object Vg
