If a substance absorbs energy but its temperature does not change, then the internal potential energy is changing.
Answer:
B. space quantization.
Explanation:
In 1921, Otto Stern developed the idea behind this experiment, while Walther Gerlach performed the actual experiment in 1922. The Ster-Gerlach experiment provides prove to the fact that the spatial orientation of angular momentum is quantized. To demonstrate the experiment, silver atoms were made to travel through a magnetic field path.
Before they hit the screen(usually a glass slide), they were deflected because of their non-zero magnetic moment. There was an expected result for this experiment, but the actual observation on the glass slide was a continuous distribution of the silver atoms that actually hit the glass. This experiment was useful in proving that in all atomic-scale systems, there was a quantization of angular momentum.
Fossil fuels burn: cause
Glaciers melt: effect (mostly; the melting ice caps are a positive feedback loop of sorts)
Climates change: effect
Rain falls in unusual amounts: effect
Cities become more industrialized: cause
Human population grows worldwide: cause
Answer:
20.5s
Explanation:
Given parameters:
Distance = 30m
Unknown:
Time = ?
Solution:
The time it will take to hop a distance of 30m using the speed for the 5m trial is the duration of the trip.
The speed for the 5m trial = 1.46m/s
Now;
Speed = 
Distance = speed x time
time = 
Input the parameters and solve;
time = 
= 20.5s
