Scientists have changed the model of the atom as they have gathered new evidence. One of the atomic models is shown below.
A large black cross in a purple circle with a black line around the purple, with 10 small green balls dispersed within the purple circle.
What experimental evidence led to the development of this atomic model from the one before it?

Aplayground slide is 8.80 ft long and makes an angle of 25.0° with the horizontal. a 63.0-kg child, initially at the top, slides all the way down to the bottom of the slide. (a) choosing the bottom of the slide as the reference configuration, what is the system's potential energy when the child is at the top and at the bottom of the slide? what is the change in potential energy as the child slides from the top to the bottom of the slide? (include the sign of the value in your answer.)
