Answer:
C. 1:30
Explanation:
The toy car is .5 feet long and the actual car is 15 feet long
This gives you a ratio of
.5:15
Now for everything you have to remember this
.5:15
=1:30
=2:45
=3:60
C is the only answer that matches any of the ratios above.
Even if you went farther in the ratios none of them would match this ratio.
Hope this helped.

Answer:
Part 1. When the balloon is filled half of the way, and placed into the freezer, it will shrink. This happens because kinetic molecular theory tells us that a decrease in temperature decreases the kinetic energy of the gas molecules in the balloon. Viscous gases like hydrogen are less likely to shrink.
Part 2. When the balloon is placed out in the hot sun, most likely the balloon will swell and grow. This happens because the kinetic energy of the gas molecules increases due to solar radiation transforming into heat energy and then transforming into kinetic energy. Sticky gases like neon are more likely to grow.

Answer:
19.3g/cm^3
Explanation:
Hey,
the formula for density is Mass/Volume so in this question you basically put the given things in the formula
D = M/V
D= 944.75/48.9
D= 19.3g/cm^3
