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 is the mass of the same rock on the earth

Abeverage can is made of 3004-h19 aluminum alloy (elastic modulus 69 gpa, tensile yield strength 285 mpa, density 2.72 g/cm^3). the dimensions on the can are approximated as a thin-walled cylinder with a height of 4.83 inches, diameter of 2.60 inches. empty the can has a mass of 14.2 g. determine: a. the wall thickness of the cylinder b. assuming a pinned-pinned condition what is the critical load? c. assuming a fixed-fixed condition what is the critical load?

Suppose that two objects attract each other with a gravitational force of 16 units. if the distance between the two objects is double, what is the new force of attraction between the two objects?
