A spring scale shows a net force of 0.8 N acting on a 1.5-kg mass. What happens to the acceleration of the object if the net force is decreased to 0.4 N?(1 point) Responses The acceleration decreases to half of its original value, or about .26 m/s2. The acceleration decreases to half of its original value, or about .26 m/s 2 . The acceleration increases to four times its original value, or about 0.13 m/s2. The acceleration increases to four times its original value, or about 0.13 m/s 2 . The acceleration increases to 2 times its original value, or about 2.13 m/s2. The acceleration increases to 2 times its original value, or about 2.13 m/s 2 . The acceleration decreases to a quarter of its original value, or about 0.13 m/s2.
