The answer is A because at a young age children will not understand and they need to learn at the appropriate level
Answer:
the acceleration of object is 3m/1s
<span>In equation form, this is often expressed as follows: The constant of proportionality in this equation is G - the universal gravitation constant. The value of G was not experimentally determined until nearly a century later (1798) by Lord Henry Cavendish using a torsion balance.</span>
By Newton's second law, we have

So, in order to give a 0.15kg body an acceleration of 40m/s^2, you need a force of
