4. When a solid object is suspended from a spring scale in air the scale reads 21.7N. The object is then completely submerged in water and the spring scale reads 16.6N. Draw a free-body diagram for the object suspended from the scale in air. You may ignore the very small buoyant force from the air. Using a Newton's 2 nd law equation for the vertical direction on your FBD determine the mass of the object. Draw a free-body diagram for...
An object suspended from a spring scale weighs 0.56 N in air. The same object completely submerged in water and suspended from the same spring scale weighs 0. P(water) = 1 g/ml = 1 g/cm^3 = 1000 kg/m^3 Draw a clearly labeled free body diagram for: i. The mass suspended from the spring balance in air ii. The mass suspended from the the spring balance in water
A 6.0 kg iron block is suspended from a spring scale and is submerged in a fluid of unknown density. The spring scale reads 3.0 N. What is the density of the fluid? The desity of iron is 7. 80 × 103 kg/m3.
A 5.0-kg block suspended from a spring scale is slowly lowered onto a vertical spring (Figure 1) . Part A What does the scale read before the block touches the vertical spring? Part B If the scale reads 34N when the bottom spring is compressed 30 mm, what is k for the bottom spring? Part C How far does the block compress the bottom spring when the scale reads 0? Express your answer with the appropriate units. Enter positive value...
7. A solid rock ,suspended in air by a spring scale, has a measured weight of 72 x(# N) newton. When the rock is submerged in water, scale reads 1/3 x(#N) newton.

A scale reads 87 N when a piece of aluminum is hanging from it. What does it read when it is lowered so that the aluminum is submerged in water? The density of alluminum is 2700 kg/mº Use g = 9.8 m/s2 Calculate answer to two decimals. QUESTION 3 3 point Weight and g: At a distance of 14,000 km from the center of Planet Z- 99, the acceleration due to gravity is 32 m/s2. What is the acceleration due...
A 305 g rock is suspended in water, with the spring scale exerting a force FE = 2.10 N on it. Find the buoyant force acting on the rock: FB = ________ N (3 SF). Find the rock's volume: V = ________ cm3 (3 SF) and the rock's density: ______ g/cm3 (3 SF)
An object suspended from a spring scale is lowered into a pail filled to the brim with water, and 4N of water overflows. The scale shows that the object weighs 6N in the water. What is the weight of the object in air?
A 130.0 g piece of copper (specific heat 0.38 J/g・°C) is heated and then placed into 400.0 g of water initially at 20.7°C. The water increases in temperature to 22.2°C. What is the initial temperature of the copper? (The specific heat of water is 4.18 J/g・°C and the density of water is 1.00 g/mL).
