How to measure the external diameter of a sphere

1 answer:

4 0

Sphere is that the circular objects in the two dimensional space (1) circle
(2) disk. Two dimensional space is a set of points and the distance of that point,The two points of Sphere that length and center.
Sphere can constructed as the named of surface form circle about any diameter. circle is the special type of the revolution replacing the circle,
sphere is the distance r is the radius of the ball and circle is the center of mathematical ball,as the center and the radius of the sphere is to respectively.
The ball and sphere has not be maintained mathematical references as a solid references. A sphere of any radius is centered at the number of zero.

garik1379 [7]

Answer:

Weathering

Explanation:

The geologic process of breaking down rocks into smaller and smaller units or pieces is known as weathering.

The physical disintegration and chemical decomposition of rocks to form sediments and soils is known as weathering.

The agents of weathering are wind, water and glacier.

Chemical weathering entails the decomposition of rocks.
Mechanical weathering is the physical disintegration of rocks.

Therefore, weathering breaks down rocks.

Erosion removes the weathered materials.

A single slit of width 0.50 mm is illuminated with light of wavelength 500 nm, and a screen is placed 120 cm in front of the sli

Vaselesa [24]

Answer:

a) 2.4 mm

b) 1.2 mm

c) 1.2 mm

Explanation:

To find the widths of the maxima you use the diffraction condition for destructive interference, given by the following formula:

$m\lambda=asin\theta$

a: width of the slit

λ: wavelength

m: order of the minimum

for little angles you have:

$y=\frac{m\lambda D}{a}$

y: height of the mth minimum

a) the width of the central maximum is 2*y for m=1:

$w=2y_1=2\frac{1(500*10^{-9}m)(1.2m)}{0.50*10^{-3}m}=2.4*10^{-3}m=2.4mm$

b) the width of first maximum is y2-y1:

$w=y_2-y_1=\frac{(500*10^{-9}m)(1.2m)}{0.50*10^{-3}m}[2-1]=1.2mm$

c) and for the second maximum:

$w=y_3-y_2=\frac{(500*10^{-9}m)(1.2m)}{0.50*10^{-3}m}[3-2]=1.2mm$

A 1210 kg rollercoaster car is

ratelena [41]

Answer: 4.98 m/s

Explanation:

You solve these kinetic energy, potential energy problems by using the fact P.E.+ K.E. = a constant as long as friction is ignored.

PEi = 0 in this case

KEi = ½mVi² = PEf+KEf = mghf + ½mVf²

½1210*8.31² = 1210*9.8*2.26 + ½1210*Vf²

½1210*Vf² = ½1210*8.31² - 1210*9.8*2.26

Vf² = 8.31² - 2*9.8*2.26 = 4.98² so Vf = 4.98m/s
