Answer from: chris3633

The resulting acceleration of Efua is $0.125 \;\rm m/s^{2}$ .

Given data:

The mass of Efua is, m = 40.0 kg.

The magnitude of applied force by Joyce is, F = 5.00 N.

The given problem is based on the Newton's Second law of motion. As per the Newton's second law, the applied force is equal to the product of mass and the acceleration of object. Therefore,

F = ma

a = F/m

Solving as,

a = 5.00 / 40

$a = 0.125 \;\rm m/s^{2}$

Thus, we can conclude that the resulting acceleration of Efua is $0.125 \;\rm m/s^{2}$ .

Answer from: mccdp55

$a=0.125\ m/s^2$

Explanation:

Given that,

Mass, m = 40 kg

The net force with which Joyce pushes Efua is 5 N.

We need to find Efua’s resulting acceleration. Let it is equal to a. Net force is given by :

F = ma

$a=\dfrac{F}{m}\\\\a=\dfrac{5\ N}{40\ kg}\\\\a=0.125\ m/s^2$

So, the acceleration is $0.125\ m/s^2$ .

Answer from: Quest

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.

$_a^z\textrm{x}\rightarrow _{a-2}^{z-4}+_2^4\alpha$

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.

$_a^z\textrm{x}+_{-1}^0\textrm{e}\rightarrow _{z-1}^a\textrm{y}$

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 $\gamma -radiations$ . this process does not change the mass number.

$_a^z\textrm{x}^*\rightarrow _a^z\textrm{x}+_0^0\gamma$

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 $\beta ^+$ -decay. in this the mass number remains same.

$_a^z\textrm{x}\rightarrow _{z-1}^a\textrm{y}+_{+1}^0e$

from the above information, we see that only alpha-decay is producing a change in the mass number of the nucleus.
