The gravity on planet a is 5.6 m/s the mass of an object is 2.6 kg, what is the weight of the
object on this new planet?

14.56 N

Explanation:

According to Newton's second law of motion,

The force acting on a body is equal to the product of its mass and acceleration acting on it.

Weight of a body on a planet is equal to the force due to gravity of the planet. So, weight is the product of mass of body and acceleration due to gravity of the planet.

Here, acceleration due to gravity on planet A is m/s² and mass of an object on it is kg.

So, weight of an object, , on planet A is given as,

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.
