Answer:
55.56kg
Explanation:
Given:
F= 52N
a=0.936m/s²
Applyinc Newton's second law, that states: force is equal to mass times acceleration.
F = ma
m=F/a =>52 / 0.936
m=55.56kg
Hello
The weight of the object is W=80 N and points downwards, in the vertical direction. The force F exerted by the forearm is perpendicular to the forearm itself, which is at an angle of
above the horizontal; therefore, the angle between the direction of the force F and the direction of the weight P is also
(but upwards). The component of the force F in the vertical direction is
and
must be equal to the weight of the object to compensate it. Therefore we can write
and from this we can find the intensity of the force F:
Answer:
A.
Explanation:
It will stay in motion unless for example, someone stops it from going.
carbon-12 and carbon-14 are differed by the neutrons count in their atoms.
<u>Explanation:</u>
The two isotopes of the carbon element are carbon-12 and 14 . The difference between them is the neutrons count in each of their atoms. This is how it works. The digit after the atom's name represents the protons and neutrons count in the atom or ion. The atoms of both carbon isotopes have 6 protons. carbon-12 atoms comprise with 6 neutrons, whereas 8 neutrons in carbon-14.
A neutral atom usually have the same counts of electron and proton, so that a neutral carbon-12 or 14 atom have 6 electrons. Although neutrons do not possess any electric charge, their mass is similar to that of protons, so different isotopes consist different atomic masses. Carbon-12 seems to be more lighter when compared with carbon-14.
