Stells [14]

ANSWER:

C) as the electrons are pushed more by the battery, they move faster through the circuit

EXPLANATION:

Electrons move very slowly. When we supply voltage the current through a wire moves which causes each electron to move in the direction of the flow of current, the electrons which were in random motions previously now move in one direction which is the direction of current,the more we supply the current the faster electrons will move in the circuit,which will cause the current to increase with increase in voltage.

A gas cylinder has a volume of 0.4 m? It contains butane at a pressure of 100 kPa and a temperature of

morpeh [17]

The pressure needed : 800 kPa

<h3>Further explanation</h3>

Given

V₁ = 0.4 m³

P₁ = 100 kPa

T₁ = 20 + 273 = 293 K

V₂ = 0.05 m³

T₂ = T₁ = 293 K

Required

The final pressure(P₂)

Solution

Boyle's Law

At a fixed temperature, the gas volume is inversely proportional to the pressure applied

$\tt \rm p_1V_1=p_2.V_2\\\\\dfrac{p_1}{p_2}=\dfrac{V_2}{V_1}$

Input the value :

P₂=P₁V₁/V₂

P₂=100 x 0.4 / 0.05

P₂=800 kPa

A supersonic airplane is flying horizontally at a speed of 2650 km/h. What is the centripetal acceleration of the airplane, if i

Andrew [12]

Answer:

$a_{c}=82617.65km/h^{2}\\ or\\a_{c}=6.37m/s^{2}$

Explanation:

Given data

Speed v=2650 km/h

Radius r=85.0 km

To find

Centripetal Acceleration

Solution

As centripetal acceleration is given as

$a_{c}=\frac{v^{2} }{r}................eq(i)$

where

v is velocity

r is the radius

Substitute the given values in eq(i)

$a_{c}=\frac{(2650km/h)^{2} }{85km} \\a_{c}=82617.65km/h^{2}\\ or\\a_{c}=6.37m/s^{2}$
