A sphere of radius 10.0cm is moulded into a uniform cylindrical wire of same radius r calculate length in millimeters
Answer:
133.33 mm
Explanation:
First we need to find the volume of the sphere. The volume of a sphere is given by:
V = (4/3) * pi * r^3
With a radius of 10 cm, we have:
V = (4/3) * pi * r^3 = 4188.79 cm3
The sphere will be moulded into a cylinder, so the volume will be the same. The volume of a cylinder is:
V = pi * r^2 * h
Where h is the height of the cylinder, and for this case, it will be the length.
The radius is the same old radius, so we have:
4188.79 = pi * 10^2 * h
h = 4188.79 / 100pi = 13.3333 cm
In millimeters, we have h = 133.33 mm

1/ u + 1/v = 1/f
( introducing magnification; m into the formula )
u( 1/u + 1/v ) =u×1/f
1 + u/v =u/f
( But u/v =1 ÷v/u= 1/m)
1 +1/m =u/f
(Supposing m is actually equal to 2, and f =30 cm, then;)1 + 1/2 =u/30
2+1= u/15
3=u/15
3×15=u
45 cm=u

Answer:
The correct answer to the following question will be Option C (sublimation).
Explanation:
Sublimation seems to be the process in which a substance or a solid changes its sequence from solid to the gaseous without moving via the form of water.From either the framework or method, we have because the category of phase change seems to be sublimation since there is a material altered to something like the gaseous state throughout the solid.Other options aren't connected to the offer scenario. Therefore the answer to the above is the correct one.
Meeta used an elastic tape to measure the length of her window to stitch a curtain. Do you think she will be able to stitch a curtain of correct measurement? Yes/No . Give scientific reason in detail, also explain the correct method to measure the length of her window.
Answer:
No
Explanation:
She will not be able to measure the length of her window accurately due to instrumental error from her choice of instrument. The elastic nature of her tape would alter the measurement because it will stretch as she is taking her readings, thus reducing the true measurement of the length of her window.
To measure the length of her window, she could use an inelastic tape rule or a metre rule. These instruments would eliminate instrumental error.

A force of 1000 Newtons is used to push a box on a flat floor. It accelerated at a rate of 5 m/s2. What is the mass of the wagon?
Answer:
67.56kg
Explanation:
Fapp+mg = ma
Fapp= applied force
mg = reactional force
g = acceleration due to gravity
Where g = 9.8m/s^2 a= 5 m/s2, Fapp= 1000N.
1000N = ma + mg
1000N = m( a+g )
1000N = m ( 5+9.8)
1000N = m×14.8
m = 1000÷14.8
m = 67.56kg.
Hence the mass of the wagon will be 67.56kg

Diffraction of white light with a single slit produces bright lines of different colors.What is the color of the central image?
Answer:
white
Explanation:
This experiment causes lines of different colors because the constructive interference depends on the wavelength, so for different wavelength, the position of the maximum will be different.
Now, in diffraction fo a single slit we always have a central maximum (for all the colors)
This means that after the diffraction, we will have that all the colors have a maximum in the center, which will produce white light again, then the color of the central image is white

- Determine the number of protons and neutrons in the nucleus of the atom of beryllium.
- Determine the structure of the nuclei of the isotopes of uranium and thorium
- Which forces are called nuclear forces.
- List the peculiarities of nuclear forces.
Solution
Note that the number of protons in the nucleus of an atom is the atomic number of that atom.
And the mass number of the atom is the sum of protons and neutrons in the nucleus of the atom.
The nucleus of an atom is the most massive part of an atom containing almost exclusively the neutrons and the protons of the atom.
- Beryllium has an atomic number of 4 and a mass number of 9.
Hence, its number of protons = atomic number = 4
(Number of protons) + (Number of neutrons) = mass number
Number of neutrons
= (mass number) - (Number of protons)
= 9 - 4 = 5
- Uranium has atomic number of 92 and mass number of 238.
Number of protons = 92
Number of neutrons = 238 - 92 = 146
Thorium has atomic number of 90 and a mass number of 232.
Number of protons = 90
Number of neutrons = 232 - 90 = 142 neutrons.
- Nuclear forces are the forces that keep the neutrons and protons of an atom bonded to the nucleus of an atom. The constituents of the atom's nucleus are called nucleons. Nuclear forces are the forces between two or more nucleons.
- The nuclear forces are about 10 million times stronger than the forces that bind atoms together in molecules and compounds.
Hence, massive energies are required to break into the nucleus of atoms.
This is why nuclear reactors produce about a million times more energy per kilogram fuel compared to chemical fuel.
However, the range of the nuclear force is short, only about 10⁻¹⁵ m, beyond which it decreases rapidly.
This is why, in spite of its enormous strength, we do not feel anything of this force on the atomic scale or in everyday life.
In Romanian/In limba romana
Rețineți că numărul protonilor din nucleul unui atom este numărul atomic al acelui atom. Și numărul de masă al atomului este suma protonilor și neutronilor din nucleul atomului. Nucleul unui atom este partea cea mai masivă a unui atom care conține aproape exclusiv neutroni și protonii atomului.
- Beriliu are un număr atomic de 4 și un număr de masă de 9.
Prin urmare, numărul său de protoni = numărul atomic = 4
(Număr de protoni) + (Număr de neutroni) = număr de masă
Numărul de neutroni = (număr de masă) - (Număr de protoni) = 9 - 4 = 5
- Uraniul are numărul atomic de 92 și numărul de masă de 238.
Numărul de protoni = 92
Numărul de neutroni = 238 - 92 = 146
Toriul are un număr atomic de 90 și un număr de masă de 232.
Numărul de protoni = 90
Numărul de neutroni = 232 - 90 = 142 neutroni.
- Forțele nucleare sunt forțele care mențin neutronii și protonii unui atom legați de nucleul unui atom.
Constituenții nucleului atomului se numesc nucleoni. Forțele nucleare sunt forțele dintre doi sau mai mulți nucleoni.
- Forțele nucleare sunt de aproximativ 10 milioane de ori mai puternice decât forțele care leagă atomii împreună în molecule și compuși.
Prin urmare, energiile masive sunt necesare pentru a pătrunde în nucleul atomilor.
Acesta este motivul pentru care reactoarele nucleare produc aproximativ un milion de ori mai multă energie pe kilogram de combustibil în comparație cu combustibilul chimic.
Cu toate acestea, domeniul forței nucleare este scurt, doar aproximativ 10⁻¹⁵ m, dincolo de care scade rapid.
Acesta este motivul pentru care, în ciuda puterii sale enorme, nu simțim nimic din această forță pe scara atomică sau în viața de zi cu zi.

How do you know this?(d)Select an equation.(e)Solve forthe time it takes for the ball to hit the ground.
Answer:
t = 5.05 s
Explanation:
This is a kinetic problem.
a) to solve it we must fix a reference system, let's use a fixed system on the floor where the height is 0 m
b) in this system the equations of motion are
y = v₀ t + ½ g t²
where v₀ is the initial velocity that is v₀ = 0 and g is the acceleration of gravity that always points towards the center of the Earth
e) y = 0 + ½ g t²
t = √ (2y / g)
t = √(2 125 / 9.8)
t = 5.05 s
Chris has a part time job as a cannon ball catcher for the circus. One day he was located an unknown distance away from the cannon. A cannonball was fired from the cannon at 425 m/s. The speed of sound was 345 m/s. Unfortunately the cannonball went past Chris 0.20 s before he heard the sound of the blast. How far away was the cannon from Chris?
show work with answer for brainliest plz
Answer: 366.56 meters.
Explanation:
Velocity of the cannon ball = 425m/s
Velocity of sound = 345 m/s
For the "position" of both, we have the equation:
Pc = 425m/s*t
Ps = 345m/s*t
Where t is time in seconds.
If the position of Chris is X, we have that if the ball reaches the position of Chris in T seconds, then the soundwave reaches the position of Chris in T + 0.20 seconds, we can write this as:
425m/s*T = X
345m/s*(T + 0.20s) = X
Now we can solve this system of equations. First we can replace the first equation in the second equation and get
345m/s*(T - 0.20s) = 425m/s*T
Now we solve this for T.
345*T + 69 = 425*T
69 = (425 - 345)*T = 80*T
T = 69/80 = 0.8625 seconds.
Now we replace this in the first equation and get:
X = 425m/s*T = 425m/s*0.8625s = 366.56 meters.
