Answer:
Object 2, which has a density of 1.9 g/cm3, since it has more density than freshwater.
the neutrons through the nucleus?
Explanation:
The correct answer is they get closer together
Going from gas into a liquid makes the molecules move closer together, which happens again when you turn it into a solid.
Answer:
C. 3.2km
Explanation:
Seeing as the swimmer travels 10.8 km in an hour, and they are asking you to find how far they have traveled after 0.3 hours, multiply 10.8 km/h by 0.3 h. The h's will cancel and you are left with 3.24km, which can be rounded to 3.2km. Hope this helps! :)
Answer:
linear cart C Vs 1/R² or log cart C Vs R
Explanation:
Gamma radiation is very high energy electromagnetic rays, but its behavior is the same as for all radiation. By the principle of conservation of energy after the radiation is emitted, it must be distributed on a spherical surface which determines the behavior of the inverse of the square.
In this experiment you are measuring the rate of counts by time (C), this must be the dependent variable since it is not controlled by the experimenter and on the other hand it measures the distance (X) this is the independent variable since it is the one that we can control.
To make a graph with this data, the counting rate must be plotted against the inverse of the squared distance (1/R²). On the Y axis the counts per second and the X 1 / R² axis, with this graph a line must be obtained.
Another graph that we can make on double logarithmic paper where the Y axis plotted the counting rate and on the X axis the distance, the slope should give -2.
C == A / R²
Log C = log A -2 log R
With either of the two graphs, the law of the inverse of the square is tested
