An aircraft cannot reach flying speed on a short runway. Someone suggests reducing its cargo load. Which of Newton's laws is bei
ELEN [110]

Answer:

Second Law

Explanation:

Newton's second law states that the acceleration caused in a body is directly proportional to the force applied and inversely proportion to the mass of the body.

This is given by :

Acceleration=\frac{Force}{Mass}

In this case the suggestion given to reduce the aircraft's cargo load is the right move as reducing the load on the aircraft will decrease the mass of the whole aircraft.  This in turn will help the aircraft to accelerate more as acceleration inversely varies with mass. Thus the aircraft will be able to reach its flying speed even on a short run way.

Hence, Newton's second law is applied.

Un átomo X posee 29 protones y de carga +2 ¿Cuántos electrones tiene?
lesya [120]

Responder:

27

Explicación:

Dado que:

Número de protones en el átomo X = 29

Carga en el átomo X = +2

Si no hay cargo neto;

número de protones = número de electrones

Sin embargo, dado que el átomo X tiene una carga de +2 (dando 2 electrones).

Por lo tanto,

Número de electrones = número de protones - número de carga en el átomo)

Número de electrones = (29 - 2) = 27
