solutions:
-50kg
-32kg
-2kg
its 50 kg because as a result of being more heavy the force that is applied to him don't makes hi go as fast as the other one
The best way for the microscopic comparison of paint chips is the standard infrared spectroscopy technique.
<u>Explanation:
</u>
The hit and run road accidents often leave paint chips with which the forensic investigation is conducted and the complete incident is recalled. The paint chips are actually multi-layered materials with several coats of paints.
The best way to make a microscopic comparison of paint chips, infrared microscopes are used which provide spectra for each of the existing layer.
There are three main sampling techniques in the infrared spectroscopy such as Transmission, Attenuated Total Reflectance (ATR) and the specular reflectance. With this technique, scientists can better judge the consequences of the incident and provide better proofs of the crime.
A) heterogeneous mixture & I believe B?
I know A is correct though
Answer:
As we have already discussed earlier, motion is the state of change in position of an object over time. It is described in terms of displacement, distance, velocity, acceleration, time and speed. Jogging, driving a car, and even simply taking a walk are all everyday examples of motion. The relations between these quantities are known as the equations of motion.
You haven't listed any choices or offered any suggested answers.

if I want to answer this question and scoop up a few points, I have to
invent an answer from scratch.
On a speed/time graph, a VERTICAL line segment represents something
that's physically impossible.
The top of the line segment is a speed that's faster than the bottom
of the segment, but the times are both the same.
A change of speed that takes no time would correspond to infinite
acceleration. That just simply sounds wrong, and it is. Can't happen.
