Explanation:
Given that, you are taking a picture of a giraffe that is standing far away from you. The image is just too small, so you swap the 60-mm-focal-length lens in your camera for a 960 mm telephoto lens such that,
![m_1=960\ mm](https://tex.z-dn.net/?f=m_1%3D960%5C%20mm)
![m_2=60\ mm](https://tex.z-dn.net/?f=m_2%3D60%5C%20mm)
We need to find the the factor with which the size of the image increases. It can be calculated by taking ratios of both ![m_1\ and\ m_2](https://tex.z-dn.net/?f=m_1%5C%20and%5C%20m_2)
So, ![\dfrac{m_1}{m_2}=\dfrac{960}{60}](https://tex.z-dn.net/?f=%5Cdfrac%7Bm_1%7D%7Bm_2%7D%3D%5Cdfrac%7B960%7D%7B60%7D)
![\dfrac{m_1}{m_2}=16](https://tex.z-dn.net/?f=%5Cdfrac%7Bm_1%7D%7Bm_2%7D%3D16)
So, the size of image increases by a factor of 16. Hence, this is the required solution.
Answer:
A.
collect samples.
Explanation:
The main goal of science is to gain knowledge about the natural world, but this goal is nearly impossible to achieve without technology.
Technologies are products or processes that are created to solve a problem and/or take care of a human need. Technology is often used in science to collect samples, make measurements, collect and store data, analyze data through computations and graphing, and access remote locations, such as outer space.

Answer:
An inelastic collision, in contrast to an elastic collision, is a collision in which kinetic energy is not conserved due to the action of internal friction. In collisions of macroscopic bodies, some kinetic energy is turned into vibrational energy of the atoms, causing a heating effect, and the bodies are deformed.
