Juan and kuri are on a carousel. juan is closer to the center of the carousel than kuri. which statement describes their tangential speeds? juan and kuri move the same distance in one revolution, but juan completes the revolution in less time and has a higher speed. juan and kuri complete one revolution in the same time, but juan travels a shorter distance and has a lower speed. juan moves a shorter distance in less time than kuri, but their speeds are the same. juan and kuri complete one revolution in the same time, so they have the same speed.

answer: question1

question2

3: 8

question 3

store d

step-by-step explanation:

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.

hi i’m sorry to call us today so we will get back with y’all and we will have to do it haha omg was the day

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
