Answer:

Interference patters of electron

Explanation:

In this phenomena, electrons were passed through a double slit and strike on a slit behind the slit, thus an interference pattern of bright and dark fringes is formed on screen. This validates that electron ( matter ) behaves like wave.

Interference is a specific characteristic exclusive to waves hence a conclusion was drawn that if matter shows this, it must also reflect like a wave.

The phenomenon that best illustrates on matter behaving like a wave instead of being a particle is called the interference patterns of electrons. In addition, this phenomenon was described by experimenting that made use of an electron wherein the wave nature of electrons was observed.

A soccerball is kicked straight out from a hill at 15 m/s and lands 42m away. how tall is the hill

ozzi

Answer:

The height of the hill is, h = 38.42 m

Explanation:

Given,

The horizontal velocity of the soccer ball, Vx = 15 m/s

The range of the soccer ball, s = 42 m

The projectile projected from a height is given by the formula

S = Vx [Vy + √(Vy² + 2gh)] / g

Therefore,

h = S²g/2Vx² (Since Vy = 0)

Substituting the values

h = 42² x 9.8/ (2 x 15²)

= 38.42 m

Hence, the height of the hill is, h = 38.42 m

Water has a mass per mole of 18.0 g/mol, and each water molecule (H20) has 10 electrons. (a) How many electrons are there in one

Allushta [10]

Answer:

total number of electron in 1 litter is 3.34 × $10^{26}$ electron

Explanation:

given data

mass per mole = 18 g/mol

no of electron = 10

to find out

how many electron in 1 liter of water

solution

we know molecules per gram mole is 6.02 × $10^{23}$ molecules

no of moles is 1

total number of electron in water is = no of electron ×molecules per gram mole × no of moles

total number of electron in water is = 10 × 6.02 × $10^{23}$ × 1

total number of electron in water is = 6.02× $10^{24}$ electron

and

we know

mass = density × volume ..........1

here we know density of water is 1000 kg/m

and volume = 1 litter = 1 × $10^{-3}$ m³

mass of 1 litter = 1000 × 1 × $10^{-3}$

mass = 1000 g

total number of electron in 1 litter = mass of 1 litter × $\frac{molecules per gram mole}{mass per mole}$

total number of electron in 1 litter = 1000 × $\frac{6.02*10{24}}{18}$

total number of electron in 1 litter is 3.34 × $10^{26}$ electron

A centrifuge in a medical laboratory rotates at an angular speed of 3500 rev/min. When switched off, it rotates 46.0 times befor

BlackZzzverrR [31]

Answer:

The angular acceleration of the centrifuge is -231.74 rad/s².

Explanation:

Given that,

Angular speed = 3500 rev/min = 366 rad/s

We need to calculate the angular displacement

Using formula of angular displacement

$\theta=2\pi n$

Put the value into the formula

$\theta=2\pi\times46$

$\theta=289.02\ rad$

We need to calculate the angular acceleration

Using equation of motion

$\omega_{f}^2=\omega_{i}^2+2\alpha\theta$

$\alpha=\dfrac{\omega_{f}^2-\omega_{i}^2}{2\theta}$

$\alpha=\dfrac{0-(366)^2}{2\times289.02}$

$\alpha=-231.74\ rad/s^2$

Hence, The angular acceleration of the centrifuge is -231.74 rad/s².
