Answer:
the acceleration will be 10 m/s^2
Explanation:
the force applied to an object and the acceleration of the object are directly proportional, as Newton's second law states:

where
F is the net force applied to the object
m is the object's mass
a is the object's acceleration
in the first example, a force F=45 N is applied to the object, giving it an acceleration of a=5 m/s^2. Therefore, the mass of the object is

In the second example, the force is doubled, so it will be F=90 N. The mass is still m=9 kg, so the acceleration will be

C. easier to build than a refracting telescope
Big mirrors used in reflecting telescopes are easier and cheaper to make than big lenses which would cost more because of the quality of glass required to make refracting telescopes
