13. circle the cart that would have the smaller acceleration if each cart was pushed with the same amount of…

Brief Explanations:

According to Newton's second - law $F = ma$ (where $F$ is force, $m$ is mass, and $a$ is acceleration), when the force $F$ is constant, the acceleration $a$ is inversely proportional to the mass $m$ ($a=\frac{F}{m}$). The total mass of the cart in Figure A is $24 + 10=34$ kg, and the total mass of the cart in Figure B is $10 + 2 = 12$ kg. Since the force applied to each cart is the same, the cart with the larger mass (Figure A) will have a smaller acceleration.

Answer:

The cart in Figure A would have the smaller acceleration because, according to Newton's second - law $F = ma$, when the force $F$ is constant, the acceleration $a$ is inversely proportional to the mass $m$, and the total mass of the cart in Figure A ($34$ kg) is greater than the total mass of the cart in Figure B ($12$ kg).
