$\huge\underline\mathtt\colorbox{cyan}{For Positively Charged:}$

By gaining electrons from the ground, the object will have a balance of charge and therefore be neutral. Grounding is the grounding of a positively charged object and involves the transfer of electrons from the ground into the object.

$\huge\underline\mathtt\colorbox{red}{For Negatively Charged:}$

If it is to have its charge removed, then it will have to lose its excess electrons. Once the excess electrons are removed from the object, there will be equal numbers of protons and electrons within the object and it will have a balance of charge.

What is the time it takes a pig to roll a distance of 6 m at a speed of 8 m/s? 0.7 m/s

Rudik [331]

Answer:

0.75 s

Explanation:

From the basic definition of sleed as distance traveled per unit time, s=d/t and making t the subject of the formula then t=d/s where t is time of traveling, d is distance covered and s is the speed. Substituting 6m for distance, d and 8 m/s for speed s then the time is calculated as t=6/8=0.75 s

Therefore, time is equivalent to 0.75 s

In which city did the wright brothers take off on their very first flight

Nezavi [6.7K]

<h2>Answer: Kitty Hawk, North Carolina </h2>

The Wright brothers, Wilbur and Orville, were pioneers of aviation, since they flew in a device heavier than air, which was inconceivable at that time.

Their first successful flight was on December 17th, 1903 in Kitty Hawk, North Carolina, which lasted only 12 seconds in which their plane (the Flyer I, with 341 kg, 6.4 m long and a wingspan of 12.3 m) traveled 37 m without touching the ground. This was achieved through the help of an external catapult that "threw" them into the air.

It should be noted that the Wright brothers only studied until high school, however, their passion for solving the problem of the human inability to fly, their perseverance and experience acquired over the years in their bicycle company, led them to reach that goal. An achievement that marked the beginning of the aviation era.

<h3>What is the Earth system?</h3>

The interactions between Earth's five systems—the geosphere, biosphere, cryosphere, hydrosphere, and atmosphere—create the conditions we are accustomed to.
The rock cycle, the food chain, the carbon cycle, the nitrogen cycle, the water cycle, and the energy cycle are a few examples found in the Earth system.
The major Earth circulation processes that move water, carbon, and nutrients renew essential elements for life and contribute to climate control. The continents, atmosphere, oceans, ice, and life on Earth are dynamic elements that constantly change and interact in a wide variety of ways.
A system is made up of four independent spheres. A change in one sphere may result in another change because the spheres interact. Fields are plowed by humans (biosphere) using farm equipment made of geosphere materials, while plants are watered by precipitation (hydrosphere) brought by the atmosphere.

How much work does Jonathan do on the bicycle pedals within the Jonathan-bicycle-Earth system during this process? $W= mgh + 0.5m*vf^2- 0.5m*vi^2$

When a slice of buttered toast is accidentally pushed over the edge of a counter, it rotates as it falls. If the distance to the

Serjik [45]

Answer:

a) 5.61 rad/s

b) 16.83 rad/s

Explanation:

Distance to the floor = 79cm = 0.79m

Rotation is <1 revolution

The toast will rotate at an angular speed that is constant while it falls. The toast will also be falling with constant acceleration due to gravity. Using equation of motion, which is

S = ut + 1/2gt²

S = 0 + 1/2gt²

S = gt², where, S = d

0.79 = 9.81t²

t² = 0.79/9.81

t² = 0.081

t = 0.28s

As the toast is accidentally pushed, it rotates as it falls. It will be landing on its edges when and if it hits the ground. The smallest angle here would then be 1/4 of the revolution. This is also the smallest angular speed.

ω(min) = ΔΦ revolution /Δt

ω(min) = 1/4 * 2π / 0.28

ω(min) = 0.5π/0.28

ω(min) = 5.61 rad/s

Since 1/4 of revolution is the minimum angle, the remaining(3/4), is the maximum angle. Thus

ω(max) = 3/4 * 2π / 0.28

ω(max) = 0.75 * 2π / 0.28

ω(max) = 16.83 rad/s
