Answer:
The first experiment measures inertial mass, while the second experiment measures gravitational mass.
Explanation:
A student conducts two different experiments to observe resistance to changes in motion, both when at rest and in motion.
In the initial experiment, an object is forcefully pushed against a flat surface while its speed is tracked by a sensor. This setup involves work done against the object's inertia, identifying the mass as inertial mass.
Conversely, in the subsequent experiment, the object is lifted or thrown upward with an applied force and the speed is recorded. Here, the mass refers to gravitational mass, as the work performed combats gravity or the object's weight.
The well-known equation...
E = m c²... does not address the origin of the mass involved.
Converting 1 kg of any mass entirely into energy generates
(1kg) · (c²) Joules of energy.
E = (1 kg) · (c²) = (1 kg) · (299,792,458 m/s)²
E = 8.9876 x 10¹⁶ Joules
To simplify, this equates to the energy needed to keep a 100-watt light bulb illuminated for about 10,402,259,010 days.
(This is roughly 28.5 million years, based on the current understanding of days and years.)
The masses of particle A, B, and C are given, with all three particles aligned linearly. The distances between them are noted. The gravitational forces are attractive, compounding when acting in the same direction. The effects on each particle are formulated based on their distances.
The city evaluates the continuous increase of carbon monoxide from different origins each year. According to calculations, in the year "C: 2019"<span> (rounded to the closest whole number), the concentration of CO will surpass the allowed threshold.
If this is not correct, feel free to inform me and I will find out the right answer. However, I am confident this is accurate.:) </span>
