The planet mars has much less gravitational force than earth. what would happen if you went to mars? a. your mass would increase. b. your weight would increase. c. your mass would decrease. d. your weight would decrease.

The planet Mars has much less gravitational force than Earth. So if you went to Mars your weight would decrease.

Option D

Explanation:

Weight = mass * gravity, hence the mass of the object remains the same at earth and at Mars. When it comes to weight, it depends upon gravity of the location.

Hence at earth, due to high gravity compared to mars, the weight value will be high, whereas when it comes to mars, due to low gravity, the weight will decrease but the mass remains the same.

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 would be 32*f
