Answer 1

no

Question 2

what does law of conservation of energy say

Answer 2

energy can neither be created nor be destroyed
it can only be transformed from one form to another

Question 3

what does law of conservation of linear momentum say

Answer 3

linear momentum of a system remains unchanged in the absence of an external force

Question 4

what does law of conservation of angular momentum say

Answer 4

angular momentum of the system remains constant if the total external torque acting on it is zero

Question 5

what does law of conservation of charge say

Answer 5

charges in form of electrons are neither created nor destroyed but are simply transferred from one body to another

Question 8

what exactly did wolfgang pauli predict

Answer 8

predicted the existence of neutrino emitting in beta-decay along with the electron using conservation laws of energy and momentum

Question 9

do laws of nature change with time

Answer 9

no
