Physics 300 Lab report: Action – Reaction The relationship, F = ma, was investigated in this experiment to demonstrate the validity of the action – reaction law, also known as the Newton’s third law. This was carried out by changing the mass attached to a balloon in motion while observing the speed under the different masses…

A taut monofilament, which ran to the other end of the room, was threaded through the straw attached to the balloon. This was followed by releasing the hand-sealed balloon opening to launch the balloon into motion. The speed of the balloon was noted. The experiment was, respectively, repeated with ten pennies and ten Yen coins. The results of the experiment, indeed, validated the law of action – reaction, which states that to every action there is always opposed and equal reaction due to conservation of momentum. Simply put, if a body A exerts a force F on a body B, body B simultaneously exerts a force F of the same magnitude on body A provided both bodies are acting along the same line. Thus, as observed in our experiment, the balloon, by releasing the pressure inside, was launched into motion with a momentum that changes in proportion to the force exerted. The moving balloon exerted this force on the attached pennies/coin, as the case maybe. Following the law of action and reaction, the pennies/coin exerted a force of the same magnitude on the balloon but in the opposite direction. We observed that as the number of the pennies increased from five to ten, which correspondingly increased the mass, the acceleration of the balloon decreased.

A trigger on the cup allows you to heat the contents of the cup when required. On press of the trigger, the wall separating the reagents punctures and water reacts with the reagent to generate heat. An average self-heating cup can raise water temperature from 20°C to
By 2014, the company had more than 300 employees and the case study of Valve shows that these employees do not operate under managers. The company follows a flat and organic structure that reduces the barriers inherent in employee-customer relationships.
Authorizing a DHCP server enables the server to lease IP addresses to clients. Creating a scope sets a range of IP addresses that the DCHP leases to the clients (Bender 27). Creating an exclusion range of IP addresses on the other hand sets a range of IP addresses that one
The most common way of loss of mass is through loss of neutrons. Particles lost have a lot of energy in them upon emission.
Radioactive decay occurs until the atom becomes stable. This means change of the nucleus continually until
It is a game. It uses random actions to prove certain trends. Probability is also used here to track progress of decay of the coins. It eliminates decayed coins against non-decayed.
Two random experiments were
The Kirchoff’s voltage law assists in the experiment as we have a charging circuit. Setting up capacitors in series or parallel connections will facilitate studying capacitance and energy stored by capacitors. The capacitance meter measures
