Which set of terms best defines what affects kinetic energy and potential energy, r respectively? 1) position, gravity
2) gravity, velocity
3) velocity, height
4) height, position​

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.

according to jean piaget, in what stage of cognitive development are children able to understand conservation task?

b. preoperational

just took it

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation
