This statment is false, the pen on a seismograph does not swing freely.
The notion <span>an empty balloon have precisely the same apparent weight on a scale as a balloon filled with air depends on the diameter of the balloon. The weight of the balloon filled with air is equal to the mass of the balloon and the mass of the air inside. The mass of air inside is equal to the density of air multiplied by the volume of the balloon. If the balloon is large, then the two masses are equal whereas if not, the mass of air inside the inflation is neglible</span>
Answer:
C: liquid
Explanation:
Liquid has the set volume as it cannot be compressed or 'expanded' like a gas. However, liquids will take the shape of the container you put them in so their shape can change.
The rock layer which marks the end of the dinosaurs is: C. KT Boundary layer.
A rock can be defined as a solid material containing minerals, which are naturally formed through the following processes:
Basically, a rock comprises of various layers which marks the age of both living and nonliving organisms, these includes:
I. Burgess Shale layer.
II. Mesozoic Layer.
III. KT Boundary layer.
Dinosaurs refers to a taxa of carnivorous or herbivorous archosaurian reptiles that are often very large and belongs to the Mesozoic era.
Basically, the Mesozoic Layer is a rock layer which marks the period when dinosaurs were still roaming the earth some million years ago.
However, dinosaurs went into extinction at the KT Boundary layer and as such it is a rock layer which marks the end of the dinosaurs.
