Awooden cylinder of length l and cross-sectional area a is partially submerged in a liquid with the axis of the cylinder oriented straight up and down. the density of the liquid is rhol. if the length of the cylinder that is below the surface of the liquid is d. a. what is the buoyant force that the liquid exerts on the cylinder? (ignore the small buoyant force exerted by the air on the part of the cylinder above the surface of the b. if the cylinder floats in the position described in the previous part, what is the density of the cylinder? (ignore the small buoyant force exerted by the air on the part of the cylinder above the surface of the liquid.)

explanation:

it is so massive and has such a strong gravitational pull its likely prevented the formation of a planet between itself and mars in the asteroid belt

answer: the correct answer is 1.

explanation: there are various process in which a radioactive nuclei decays:

1) alpha decay: in this process, a heavier nuclei decays into lighter nuclei by releasing alpha particle. the mass number is reduced by 4 units.

2) electron capture: in this decay process, a parent nuclei absorbs an electron and gets converted into a neutron. simply, a proton and an electron combines together to form a neutron. mass number does not change in this process.

3) gamma ray emission: it is a decay process in which an unstable nuclei gives excess energy by a spontaneous electromagnetic process. this decay releases . this process does not change the mass number.

4) positron emission: it is a type of decay process, in which a proton gets converted to neutron and an electron neutrino. this is also known as -decay. in this the mass number remains same.

from the above information, we see that only alpha-decay is producing a change in the mass number of the nucleus.
