The answer
the main formula is given by
Q=mSDT
 where m= mass
             s= specific heat
             DT= <span>change in temperature

so  Q =  50.89 x 1.8x 4.11 = 376.48</span>

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.
