A100 cm3 block of lead weighs 11n is carefully submerged in water. one cm3 of water weighs 0.0098 n. what volume of water does the lead how much does that volume of water what is the buoyant force on the will the lead block sink or float in 3. the same 100 cm3 block of lead is carefully submerged in a container of mercury. one cm3 of mercury weighs 0.13 n. what volume of mercury is how much does that volume of mercury what is the buoyant force on the d) will the lead block sink or float in 4. according to problems 2 and 3, does an object’s density have anything to do with whether or not it will float in a particular liquid? justify your answer.

How would doubling the made of an object change the objects potential energy

Chapter 23, problem 075 the figure shows a geiger counter, a device used to detect ionizing radiation (radiation that causes ionization of atoms). the counter consists of a thin, positively charged central wire surrounded by a concentric, circular, conducting cylindrical shell with an equal negative charge. thus, a strong radial electric field is set up inside the shell. the shell contains a low-pressure inert gas. a particle of radiation entering the device through the shell wall ionizes a few of the gas atoms. the resulting free electrons (e) are drawn to the positive wire. however, the electric field is so intense that, between collisions with gas atoms, the free electrons gain energy sufficient to ionize these atoms also. more free electrons are thereby created, and the process is repeated until the electrons reach the wire. the resulting "avalanche" of electrons is collected by the wire, generating a signal that is used to record the passage of the original particle of radiation. suppose the radius of the central wire is 24 âµm, the inner radius of the shell 2.3 cm, and the length of the shell 14 cm. if the electric field at the shell's inner wall is 2.8 ă— 104 n/c, what is the total positive charge on the central wire?
