Explanation:
power = Force × distance /time
power = 944N × 12.4m/36secs
power = (944×12.4/36)Nms—¹
power = 390.2Nms—¹ or 390.2Watts or 390.2Js—¹
Answer:
A) conductors
Explanation:
A conductor can be defined as any material or object that allows the free flow of current or electrons (charge) in one or more directions in an electrical circuit. Some examples of a conductor are metals, tungsten, copper, aluminum, iron, graphite, etc.
Basically, the main purpose of a conductor in physics is to provide a low-resistance path between electrical circuits or components. This low-resistance path is to ensure that the electrical components allows the free flow of electrons and thus, enabling charge transfer.
Hence, the electrons in conductors move about more freely than the electrons in insulators which is why this type of material can be used to create electric circuits because it would significantly provide a low-resistance path between the electric circuits.
They would hire a street urching and suspend him on a wooden frame.
Then they would charge a glass rod by rubbing it on a cloth and then touch the boy.
Done several times, he would accumulate charge so that bits of papers, leaves and feathers were attracted to him.
The force applied to an object is said to be a product of its mass and the acceleration. For this case, acceleration is the reading on the gravitometer. We calculate as follows:
F = mg
39.36 N = m(9.83 m/s^2)
m = 4.00 kg
Hope this answers the question. Have a nice day.
In our community, every person takes a certain role in a way that they contribute something for the development of the community. Certain interactive roles include trainings, team buildings, meetings, fund raising, and etc. Every individual has also gained their own statuses depending on what they have achieved and what they have contributed as well. Those individuals that are classified in the higher statuses are those who are experienced and trained to lead. These roles and statuses help our community become better as well as helping the youth to be great models and individuals in the future.
