An object is moving with constant speed in a circular path. The object’s centripetal acceleration remains constant in A) magnitude, only
B) direction, only
C) both magnitude and direction
D) neither magnitude nor direction

I saw this question was asked but the answers varied and I’m confused.

what was the acceleration of the 2 kg cart?

⇒ 16.0 cm/s2

what was the acceleration of the 4 kg cart?

⇒ 8.1 cm/s2

what was the acceleration of the 6 kg cart?

⇒ 5.3 cm/s2

b.a device that inputs heat into a cool object

the answer is a. hope this .

the best answer for these questions would be:

1.            c. is smaller

2.            d) concrete operational

3.            b) interaction with the environment – the children interact with their environment can them learn more.

4.            a) parents who reason openly with children can limit a child’s cognitive ability.
