What might happen if transformers didn't exist?
Electricity could not be distributed through power lines to people's homes
The electricity in your house might have an extremely high voltage

The direction of the electric current in your home might switch back and forth
Electricity could not be created at power plants

The electricity in your house might have an extremely high voltage

Explanation:

To travel efficitenly elelectricty needs to be at a high voltage and transformers take it town to a resonable level.

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 would be kevlar ^^
