A solid block is attached to a spring scale. The reading on the scale when the block is completely immersed in water is 24.8 N , and the reading when it is completely immersed in alcohol of density 806 kg/m3 is 25.8 N What is the block's volume? What is the block's density?
A wooden ball with a weight of 16.0 N hangs from a string tied to a spring scale. When the ball is at rest, exactly 50% submerged in water, the spring scale reads 6.00 N. For this problem, we will use a density of water of 1000 kg/m^3, and we will use g = 10.0 m/s^2. If the ball was only 20.0% submerged in water instead, what would the spring scale read? _______ N Part (b) HomeworkUnanswered A wooden ball...
A solid block is attached to a spring scale. When the block is suspended in air, the scale reads 20.1 N; when it is completely immersed in water, the scale reads 16.7 N. A.) What is the volume of the block? B.) What is the density of the block?
A solid block is attached to a spring scale. When the block is suspended in air the scale reads 15.0 N; when it is completely immersed in water the scale reads 13.1 N. (a) What is the block's volume? _____ m3 (b) What is the block's density? ______kg/m3
A solid block is attached to a spring scale. When the block is suspended in air, the scale reads 23.4 N; when it is completely immersed in water, the scale reads 16.3 N. Part A What is the volume of the block? Express your answer using two significant figures. Part B What is the density of the block? Express your answer using two significant figures.
A wooden ball with a weight of 24.0 N hangs from a string tied to a spring scale. When the ball is at rest, exactly 50% submerged in water, the spring scale reads 3.00 N. For this problem, we will use a density of water of 1000 kg/m3, and we will use g = 10.0 m/s2. (b) Determine the density of the ball. (c) Determine the volume of the ball.
Consider hanging a block with mass m=1.0 kg from a spring with spring constant k=98 N/m. a) How much is the spring stretched at the equilibrium position (the position where the block hangs without bouncing)? b) If we lift the block up to the position where the spring is unstretched, and then let it go, what's the maximum speed of the block as it bounces? (neglect any friction) c) At the lowest point of the block's bounces, how much further...
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.
