What distance does an object travel in one lap around a circle?

Physics

Let say the circle is of radius R

then one lap is means the total distance the total length of the circle

here the length of circle is same as circumference

so it is given as

L = 2\pi R

So here the length of lap is given as length of circle which is given as above

An object taking one lap around the circle will be covering a distance equal to the circumference of the circle.

Explanation

1 lap around a circle means one complete rotation of a track which is circular. So the distance covered in covering one complete circle will be equal to the circle circumference.

Let us consider, R as the circle radius, then the distance covered by an object for a single lap will be equal to the circle circumference which is equal to 2πR.

The difference between Lincoln's plan of reconstruction and the Radical Republicans' is that Lincoln wanted to reunite the union
Oduvanchick [21]

Answer:

The differences between the Lincoln, Johnson, and Congress Reconstruction plans include: Although both the Lincoln and Johnson plan were open to readmission of the southern States, Congress claimed that the two administrations were too lenient and sought stiffer punishment for the States

The aspect of Abraham Lincoln's plan for reconstruction in the South that made it differ from the plan of congressional leaders was that Lincoln's plan was more focused on helping the South rebuild than on punishing it and the Radical Republicans' reconstruction offered all kinds of new opportunities to African Americans, including the vote (for males), property ownership, education, legal rights, and even the possibility of holding political office. By the beginning of 1868, about 700,000 African Americans were registered voters.

Reconstruction encompassed three major initiatives:

1. restoration of the Union

2. transformation of southern society

3.enactment of progressive legislation favoring the rights of freed slaves

Your friend asks you for a glass of water and you bring her 5 milliliters of water. Is this more or less than what she was proba
Eddi Din [679]
Probably not what you were expecting... the average bottle of water is 24 ounces. 5 milliliters is about the amount of water in a spoon. Hope this helps!!!

An electron and a proton are held on an x axis, with the electron at x = + 1.000 m and the proton at x = - 1.000 m. Part A How m
r-ruslan [8.4K]

PART A)

Electrostatic potential at the position of origin is given by

V = \frac{kq_1}{r_1} + \frac{kq_2}{r_2}

here we have

q_1 = 1.6 \times 10^{-19} C

q_2 = -1.6 \times 10^{-19} C

r_1 = r_2 = 1 m

now we have

V = \frac{Ke}{r} - \frac{Ke}{r}

V = 0

Now work done to move another charge from infinite to origin is given by

W = q(V_f - V_i)

here we will have

W = e(0 - 0) = 0

so there is no work required to move an electron from infinite to origin

PART B)

Initial potential energy of electron

U = \frac{Kq_1e}{r_1} + \frac{kq_2e}{r_2}

U = \frac{9\times 10^9(-1.6\times 10^{-19}(-1.6 \times 10^{-19})}{19} + \frac{9\times 10^9(1.6\times 10^{-19}(-1.6 \times 10^{-19})}{21}

U = (2.3\times 10^{-28})(\frac{1}{19} - \frac{1}{21})

U = 1.15\times 10^{-30}

Now we know

KE = \frac{1}{2}mv^2

KE = \frac{1}{2}(9.1\times 10^{-31}(100)^2

KE = 4.55 \times 10^{-27} kg

now by energy conservation we will have

So here initial total energy is sufficient high to reach the origin

PART C)

It will reach the origin

Calculate the work done by the cyclist when his power output is 200 W for 1800 seconds.
Kobotan [32]

Answer:

3.6 × 10^5 J

Explanation:

Work Done = Energy

Energy = Power × time

Energy = 200 × 1800

= 360000 J

W =

3.6 \times 10 {}^{5} j
