What is the centripetal force acting on a 1.5 kg mass moving in a circular path with a centripetal acceleration of 18 m/s2

How is the acceleration of an object in uniform circular motion constant? a - in magnitude only b - in direction only c - in both magnitude and direction d - in magnitude, direction & orientation

Calculate the volume of this regular solid. what is the volume of the cone? round your answer to the nearest hundredth

"if the pressure acting on an ideal gas at constant temperature is tripled, its volume isa) reduced to one-third.b) increased by a factor of three.c) increased by a factor of two.d) reduced to one-half"
