Answer: 9800 N
Explanation:
According to Hooke's law, the elongation of a spring is directly proportional to the modulus of the force applied to it, as long as the spring is not permanently deformed. This law is mathematically defined as follows:
Where:
is the elastic constant of the spring in this situation
is the measure of the compression of the spring
Solving the equation:
This is the force applied to the scale
Extinct<span> might be a word you associate with animals that lived long ago, like the dinosaurs, but did you know that over 18,000 species are classified as "threatened" (susceptible to extinction) today? Scientists involved in wildlife conservation have a tough job; they are in charge of determining what needs to be done to prevent a species from becoming extinct. Habitat, food supply, and impacts of local human populations are just a few of the factors these scientists take into account. It is a lot to keep track of for a single location, but the job becomes even harder when it is a migratory animal. In this science project, you will get a firsthand look at their job. You will access </span>real<span> data about migratory birds and use satellite images to analyze their habitats, then come up with a conservation plan to protect the species from extinction.</span>
The following statements are correct:
1. Graduated cylinder are used to measure volume.
2. Always read a graduated cylinder from the bottom of the meniscus.
Graduated cylinders are one of the instruments used to measure liquid substances in the laboratory. The most accurate way of reading measuring cylinder is to record the value at the bottom of the meniscus.
I think it’s a because if u do the math that’s what it says
Answer:
The quantum theory
Explanation:
The theory that assumes that energy exists in individual units called quanta, in the same way that matter has individual atomic units.
