Question

Need ASAP You have two identical pure silver ingots. You place one in a glass of water and observe it to sink to the bottom. You place the other in a container full of mercury and observe that it floats. Comparing the buoyant force in the two cases you conclude that A) the buoyant force in water is smaller than that in mercury. B) the buoyant force in the water is equal to that in mercury C) the buoyant force in the water and that in mercury is non-zero. D) the buoyant force in the water is larger than that in mercury. E) No conclusion can be made about the respective values of the buoyant forces. A 0.400 kg piece of metal at 373 K is dropped into a 0.100 kg aluminum cup containing 0.500 kg of water at 288. K The final temperature of the system is 313. K What is the specific heat of the metal, assuming no heat is exchanged with the surrounding? The specific heat of aluminum is 900 J/(kg-K). A) 1.90 times 10^3 J/(kg-K) B) 2.27 times 10^3 J/(kg-K) C) 4 28 times 10^3 J/(kg-K) D) 3.30 times 10^3 J/(kg-K) E) 3.80 times 10^3 J/(kg-K) The first satellite that was launched into orbit around Earth was Sputnik 1 on 4 October 1957. It had an average radius of 6.97 times 10^6 m from the center of the earth Assuming a circular orbit what is the orbital speed of the satellite? The mass of Earth is 5.97 times 10^24 kg and G = 6.67 times 10^-11 N-m^2/kg^2. A) 6.23 times 10^3 m/s B) 7.97 times 10^3 m/s C) 1.10 times 10^3 m/s D) 7.56 times 10^3 m/s E) 1.34 times 10^4 m/s In simple harmonic motion the acceleration is proportional to A) the amplitude. B) the displacement. C) the frequency. D) the velocity. E) all of the above When you blow some air above a paper strip, the paper rises This is because A) the air above the paper moves slower and the pressure is higher. B) the air above the paper moves fatter and the pressure is lower. C) the air above the paper moves slower and the pressure is lower. D) the air above the paper moves faster and the pressure is higher. E) the air above the paper moves faster and the pressure remains constant.

Explanation / Answer

26). Since sliver floats in mercury and sinks in water that means upward force on silver in mercury is more than that in silver(since weight of silver is same for both cases).

Then we know that upward force experienced by the object in liquid is known as Buoyant Force.

Hence correct option: A). the buoyant force is smaller in water than that in mercury.
