It is true that Ernest Rutherford contributed significantly to the theory of atomic structure.
He observed that particles with a positive charge deflected when passing through a thin sheet of gold foil concluded that the positive part of the atom is small and dense.
The Ernest Rutherford experiment describes planetary model of an atom. According to the model, an atom has a tiny, compact, positively charged centre called a nucleus, where almost all of the mass is concentrated, while light, negatively charged particles called electrons orbit far around it, much like planets orbit the Sun. In his experiment, the observation that a positive charge is deflected through a thin sheet of gold foil led to the conclusion that the deflection some of the positive charge occurs in a small region of the atom while the majority passed through the atom (which was also concluded to be empty space).

The price elasticity of demand for widgets is 0.5. assuming no change in the demand curve for widgets, an increase in sales of 8 percent implies a(n):________
The demand for widgets has a price elasticity of 0.5. If we assume no change in the demand curve for widgets, an increase in sales of 8 percent implies a(n) 32% reduction in price.
Solution and ExplanationThe basic formula for the price elasticity of demand coefficient is:
Percentage change in quantity being demanded/percentage change in the price
What is Demand elasticity?Demand elasticity the price elasticity of demand (PED) of a good is a measurement of how responsive the quantity demanded is to the price.
Almost all goods see a decrease in quantity demanded when prices rise, however certain goods experience this decrease more than others.
When a price increases by 1% while all other factors remain constant, the price elasticity provides the percentage change in the quantity required. If the elasticity is 2, a 1% increase in price results in a 2% decrease in the amount demanded.
Other elasticities gauge how changes in other factors affect the quantity needed (e.g., the income elasticity of demand for consumer income changes).

i) Most liquid that conduct electricity are solution of—————and—————.

The volume of the solid is [tex]V=128\frac{r^{3} }{3}[/tex]
What do you understand by Volume ?
A liquid, solid, or gas's volume is the amount of three-dimensional space it occupies. Although there are many different units that can be used to indicate volume, the most common ones are liters, cubic meters, gallons, milliliters, teaspoons, and ounces.
base is x2+y2=(2r)2
==>y=-√(4r2-x2) ,√(4r2-x2)
So each cross section parallel has base = √(4r2-x2) - -(√(4r2-x2)) = 2√(4r2-x2) and height = base
So area of each cross section is 2√(4r2-x2)*2√(4r2-x2)= 4(4r2-x2)
Now we integrate from left side of circle to right side of circle (-2r to 2r)
V = 4 ∫[ -2r to 2r] (4r2-x2)dx
V = 4 (4r2x - x3/3) [ -2r to 2r]
V = 4 [(4r2(2r) - (2r)3/3) - (4r2(-2r) - (-2r)3/3)]
V = 4 [ (8r3 - 8r3/3) - (-8r3 + 8r3/3)]
V = 4 (16r3 - 16r3/3)
V = 4 (32r3/3)

And the object will fall at 160ft/sec speed.
Velocity, both initial and finalWhen gravity first exerts force on an object, its initial velocity defines how quickly the object moves. The final velocity, on the other hand, is a vector quantity that measures the
The position of an object dropped from a height of 1000 ft. is given by s = 1000 – Vot – 16[tex]t^{2}[/tex], or 1000 – 16[tex]t^{2}[/tex] for Vo = 0, s being the distance from the ground.
The equation s(t) = Vot – 16[tex]t^{2}[/tex] is the height reached when propelled upward at a velocity of Vo.
An object dropped from a height if 1000 ft. will have a velocity of
Vf = Vo + gt = Vo + 32t = 0 + 32(5) = 160 ft/sec.
The distance fallen in this 5 second is s = Vot + [tex]\frac{gt^2}{2}[/tex] = Vot + 16[tex]t^{2}[/tex] = 0 + 16([tex]5^{2}[/tex]) = 400 feet, making the position, or distance, from the ground 600 feet.
The formula d = Vot + 16[tex]t^{2}[/tex] or 16 [tex]t^{2}[/tex]with an initial velocity of Vo = 0 determines the distance that actually fell in t seconds.
The position of an object dropped from a height of 1000 feet can be calculated using the formula s = 1000 – Vot – 16t2, or 1000 – 16t2 for Vo = 0.

Calculate the mass of nitrogen dissolved at room temperature in an 80.0-l home aquarium. assume a total pressure of 1.0 atm and a mole fraction for nitrogen of 0.78.
The mass of nitrogen is calculated as 1.092 grams
CalculationAccording to Dalton's Law of partial pressure:
Pn2 = Ptotal Xn2
Were,
Pn2is the partial pressure of nitrogen
Ptotal is the Total pressure
Xn2is the mole fraction of nitrogen
Given:
Total pressure = 1.0 atm
Mole fraction of nitrogen = 0.78
Partial pressure of nitrogen:
Pn2= 1.0 x 0.78 atm
Partial pressure of nitrogen = 0.78 atmAccording to Henry's law:
Solubility = Henry's constant (k)×Partial pressure
k = 6.26×10⁻⁴ mol/L-atm
Thus,
Solubility of nitrogen = 6.26×10⁻⁴ mol/L-atm×0.78 atm = 4.8828×10⁻⁴ mol/L

So, Moles of nitrogen gas dissolved:
Moles = Solubility (Concentration dissolved) ×Volume
Moles = 4.8828×10⁻⁴ mol/L×80.0 L = 0.0390 moles
Also,
moles = mass (m) / molar mass (M)
mass of nitrogen = moles x molar mass
