7. What voltage is required to move 6A through 10?

60V

Explanation:

Given parameters:

Current  = 6A

Resistance  = 10ohms

Unknown:

Voltage  = ?

Solution:

From ohms law we know that:

          V  = IR

V is the voltage

I is the current

R is the resistance

             V  = 6 x 10  = 60V

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.

the answer to this is proletariats.

hope this : )
