Several volcanoes have been observed erupting on the surface of one of jupiter's closest moons. suppose that material ejected from one of these volcanoes reaches a height of 5.16 km after being projected straight upward with an initial speed of 133 m/s. given that the radius of this particular moon is 1980 km, calculate its mass.

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.

An example of environmentally learned behavior is aggressive behavior, i grew up seeing many aggressive people in my life and a slowly started picking up those traits however i was able to call myself out and not give in to those traits.

You need to be more specific.  i really don't know what a "motion map" is.you can draw a graph of an object's position, distance, displacement, speed,velocity, or acceleration versus time, or you can draw a graph of the object's x-position versus its y-position and not give any information about time at all.if the graph presents position or displacement against time,  then constant velocity is a straight line . . i.e. a line that has  constant slope.if the graph shows speed against time, then constant velocityis a horizontal piece of line.if the graph shows acceleration against time, then constant  velocity is a piece of line that lies on the x-axis . . it's value is zero.
