The resistance of a circuit is given by V/I where V is the voltage and I is the current. The resistance of two resistors that are in parallel is given by equation 1. On the other hand, when the resistors are in series the resistance of two resistors given by DMM was used to measure the resistance of the small board resistors, and the values recorded
Power storage: solar power can be put away in solar batteries and warm thermal solar frameworks for warming homes. At the point when there is light, the panels charge the batteries. Amid the night and climate conditions without the sun, the batteries are utilized to power the lighting (Conservative critic).

The percentage of greenhouse gases in the atmosphere is constantly increasing because of massive industrialization and use of fossil fuel resources. The constant increase of greenhouse gases in the atmosphere is disturbing the balance between various natural processes. The balance between natural processes is important to maintain a healthy temperature.
Field trips enable us to have a better understanding of any discipline that is under study. By actually going to an area and studying it, we are able to extend the knowledge from the classroom into the real world. Such practical experiences facilitate a correlation between theory and what actually exists in an area.
The expansion of air that occurred when the bottle was allowed to return to its original shape and volume was accompanied by a decrease in the temperature of air inside the bottle. These observations indicate that when air is compressed, its temperature increases, and when air expands, its temperature decreases.
Contrary to urban water cycle, the water cycle or hydrologic is a constant cycle where water evaporates, goes into the air and becomes a cloud, precipitates, and afterward dissipates as rain once more. This procedure rewinds
NASA needed to select one low-cost budget mission set to be launched by 2016. This drew competition from a number of teams so NASA narrowed it down to three, before choosing the final one. NASA’s selection was a proposal by InSight to land on Mars and see if its interior core is solid or liquid, closing the group of finalists.

Contact forces are grouped into two (normal and friction forces). The normal force is perpendicular to the contact force while a friction force is parallel to the contact surface. On the other hand, a friction force is a type of force that acts on a moving body and it is always parallel to the motion of the object.
However, the development of a bullet proof glass (commonly referred to as ballistic glass) remains to be regarded among the leading achievements of material science (Stewart, 2009).

The changes in seasons come about as a result of the amount of light from the sun hitting the surface of earth since the earth is constantly revolving around the sun. The question this paper seeks to answer therefore is what actually accounts
Static friction is not necessarily always more than kinetic friction even though the coefficient of static friction is more than the coefficient of kinetic friction. This is because static friction is not constant and depends upon the force applied to the body to move it which is a bit less than limiting friction.
It is well known that every object on the earth’s surface experiences a downward force due to the earth’s gravitational field. Due to this force of gravity, all objects above the earth’s surface will
enomenon can be explained from Newton’s second law of motion which states that the acceleration of a body as produced by a net force is directly proportional to the magnitude of the net force, and it occurs in the same direction as the net force and inversely proportional to

After the wave is reflected by an object, it changes frequency, and the radar machine interprets the frequency in a calculation of speed. The change is known as the Doppler Effect or Doppler Shift. Radar speed detectors are the most popularly used method for identifying speeding motorists.
Wiles demonstrates to a group of stunned mathematicians that he has provided the proof of Fermat's Last Theorem (the equation x" + y" = z", where n is an integer greater than 2, has no solution in positive numbers), a problem that has confounded scholars for over 350 years.
A vector is an amount that has both magnitude and direction. Illustrations of vectors are speed, acceleration, and force. While it is simple to include, duplicate, or subtract scalars, vector expansion, it is not direct to increase and subtract.

Average velocity is the change in the position of an object in a given direction, divided by the time it took for the object to move from the initial position to the final position. The position vector r extends from the origin to the particle, while the velocity vector v points in the direction of the particle's motion. Other variables, which are appropriate for describing a moving particle, can be defined in terms of these elementary variables.

The brain-eating amoeba in most cases finds suitable thriving conditions in soil and warm water, especially in rivers, hot springs, and lakes. The first identification of the brain-eating amoeba occurred in Australia. However, researchers believe that Naegleria fowleri evolved in the United States of America (Cajigal, 8).
The tap water came from pipes that were connected to a large water tank. These pipes were often rusty which is quite a common occurrence in the country and thus this tap water can generalize to the rest of Korea. A variety of test equipment was used for the study. The results concluded that tap water is safe in the particular apartment building.
