500N 4) In the drawing to above: a. How much force is the physics student exerting on the rope? In what direction? b. How much force is the wall excrting on the rope? In what direction? c. Would the Physics student be moving? If yes, is he accelerating? d. What is the net force on the force gauge? e. What would happen if the wall stopped exerting any force? f. What happens if the Physics student is standing on ice? g. What is the force between the student and the ground called? h. Draw and label arrows on the draw and label arrows on the diagram to represent three sets of force pairs

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.

it breaks and dirupture other materials and other sencews from the bottom

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !
