In mechanics, the normal force<span> is the component, perpendicular to the surface (surface being a plane) of contact, of the contact </span>force<span> exerted on an object . We calculate as follows:
</span>∑F along x = 0 = F - Fn
<span>
Fn = F = mg = 7.52(9.81) = 73.77 N <------OPTION B</span>
Nuclear fission is seperating an atom so product is b.
Energy is released during nuclear fussion. Mass is converted into energy because E=mc^2, this is the energy that is released
Answer:
The mass of G1 at all times during this trial was <u>0.5</u> kg.
The velocity of G1 + G2 after the collision was <u>-1.24</u> m/s.
The momentum of G1 after the collision was <u>-2.10</u> kg · m/s.
Explanation:
i got it right
Answer:
El peso es de 882 newton.
Explicación:
El helicóptero se detiene a la altura en la que volaba para dejar caer una caja de 90 kg al suelo, el peso de la caja llega hasta los 882 Newton porque el peso es una fuerza dirigida hacia el centro de la tierra y depende de la gravedad. La fórmula del peso es multiplicar la masa por la gravedad, de modo que cuando se multiplican 90 kg de masa por 9,8 metros / seg2, obtenemos el peso del objeto que es 882 newton.
