Scientists have changed the model of the atom as What experimental evidence led to the development
they have gathered new evidence. One of the atomic
of this atomic model from the one before it?
models is shown below.
• A few of the positive particles aimed at a gold foil
seemed to bounce back.
O The colors of light emitted from heated atoms had
very specific energies.
Experiments with water vapor showed that
elements combine in specific proportions.
Cathode rays were bent in the same way whenever
a magnet was brought near them.

Urgent pls a. coal consumption levels off and remains flat. b. petroleum, natural gas, and renewables show an increase in consumption c. more nonrenewable resources continued to be consumed than renewable. d. there is little projected increase in nuclear energy use. e. carbon dioxide emissions are projected to decline as we approach 2040. global energy consumption is defined as the total energy used by an individual or organizations from around the world. use the graph above to analyze the projected energy consumption from now until 2040. which statements in the prompt apply? a) a, b, d b) b, c, d c) a, c, d d) a, b, c, d

Currents in dc transmission lines can be 100 a or higher. some people are concerned that the electromagnetic fields from such lines near their homes could pose health dangers. for a line that has current 150 a and a height of 8.0 m above the ground, what magnetic field does the line produce at ground level? express your answer in teslas and as a percentage of the earth’s magnetic field, which is 0.50 g. is this value cause for worry?

Which model displays the change in a gas when the temperature of the gaseous system decreases?
