The buoyant force on an object is dependent on .
a. the shape of the object
b. the volume of the object
c. the mass of the object
d. the object’s density

PLEASE ANSWER ASAP THANKS!!

d. The objects density

Explanation:

Density is the measure of how much an an object will sink or float in liquid or gas. The density of the liquid or gas is also a factor in how much the object will sink or float.

explanation:

i can do 50 in a row ( but i get so tired after that)

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.
