PLEASE HELP NOT A LOT OF TIME LEFT A vector is drawn on an x-y plane. It has a magnitude of 65.1 centimeters and a direction of 28.0 degrees below the positive x-axis. What is the x-component of this vector?

A. 30.6cm
B. 65.1cm
C. 27.1cm
D. 57.5cm

answer: question1

1,000 tons

question2

3: 8

question 3

store d

step-by-step explanation:

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.
