Two forces are applied to a 17kg box, as shown. The box is on a smooth surface Which statement best describes the acceleration of the box?

A. the box accelerated to at 1.0 m/s² to the right because the net force is 17N to the right.

B. The box accelerates at 1.9 m/s² to the right because the greater force is to the right.

C. The box accelerates at 3.0 m/s² because the combined force cause the box to accelerate.

D. The box does not accelerate, because neither the force is large enough to move the box.

A. the box accelerated to at 1.0 m/s² to the right because the net force is 17N to the right.

Explanation:

To solve this problem, we need to find the net force acting on the body;

   Net force  = Forward force  - Backward force

  Forward force  = 35N

  Backward force  = 18N

 Net force  = 35N  - 18N = 17N

 So;

   Net force  = mass x acceleration

        17  = 17 x acceleration

        Acceleration  = 1m/s²

Therefore, the body moves in the forward direction with an acceleration of  1m/s²

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
