Hope this helps!! may I have brainliest? :)
Compression, shearing and tension are the three main types of stresses faced by rocks. In regards to the force of compression, external force acts on the rock to squeeze it until it disintegrates. In case of shearing, the rock is pulled in two opposite directions by force. This ultimately results in the rock breaking down into pieces. Tension is another force that pulls the rock, making it thin in the middle. This way the rock disintegrates as it becomes weaker and weaker in the middle. Most of the rocks present in the earths crust are hugely affected by these three forces.
Answer:
2:1
Explanation:
It is given that,
The diameter of a white blood cell is 12 micrometers
The diameter of white blood cell according to a model is 24 micrometers.
We need to find the ratio of model size to actual size. It can be done as follows :
Hence, the ratio of model size to actual size is 2:1.
It i believe it would be 7.3 × 10∧3.
correct me if im wrong
