Two capacitors with capacitances of 1.0 m F and 0.50 m F, respectively, are connected in series. The system is connected to a 10
forsale [732]

Answer:

Therefore energy is stored in the 1.0 mF capacitor is 5.56×10⁻⁹ J

Explanation:

Series capacitor: The ending point of a capacitor is the starting point of other capacitor.

If C₁ and C₂ are connected in series then the equivalent  capacitance is C.

where     \frac{1}{C} =\frac{1}{C_1}+\frac{1}{C_2}

Given that,

C₁ = 1.0 mF=1.0×10⁻³F  and  C₂ = 0.50mF=0.50×10⁻³F  

If C is equivalent capacitance.

Then    \frac{1}{C} =\frac{1}{1.0}+\frac{1}{0.5}

\Rightarrow \frac{1}{C} =\frac{3}{1}

\Rightarrow C=\frac{1}{3} mF

Again given that the system is connected to a 100-v battery.

We know that

q=Cv

q= charge

C= capacitor

v= potential difference

Therefore

q=(\frac{1}{3} \times 10^{-3}\times10) C

 =\frac{10^{-2}}{3} C

The electrical potential energy stored in a capacitor can be expressed

U=\frac{q^2C}{2}

q= charge

c=capacitance of a capacitor

Therefore energy is stored in the 1.0 mF capacitor is

U=\frac{q^2C_1}{2}

\Rightarrow U=\frac{(\frac{10^{-2}}{3})^2\times 10^{-3} }{2}

\Rightarrow U= 5.56\times 10^{-9} J

The work function for cesium is 1.96 eV. (a) Find the cutoff wavelength for the metal, (b) what is the maximum kinetic energy fo
romanna [79]

Answer:

Explanation:

λ = hc/¢

Where

h = the Plank constant 6.63 x 10-34 Is

C = 3.0×10^8

¢= 1.96eV

= (6.63×10^-34Js)×(3×10^8)÷( 1.96eV) × 1eV/1.6×10^-19J

= (1.989×10^-25)÷( 1.96eV)×1eV/1.6×10^-19J

= 6.342×10^-7m

B) maximum kinetic energy

= K=hf−ϕ ........1

ϕ = hc

Where

​ h = constant 6.63 x 10^-34Js

ϕ= 1.96eV

Recall

λ =425×10^-9m

f = frequency in Hz

f = c / λ

C = 3.0×10^8

f = 3.0×10^8 / 425×10^-9m

f = 0.000705Hz

From equation 1

K = (6.63 x 10^-34Js×0.000705Hz )- 6.63 x 10^-34Js×3.0×10^8

= 4.68×10^-37 - 1.989×10^-25

= - 1.98×10^-25J

A small rescue helicopter has 4 blades, each 4m long and 50kg in mass, and it carries a load of 1000kg. a) Find the rotational k
Tomtit [17]

Answer:

A) KE_rot= 5.26 x 10^(5) J

B) KE_trans = 2 x 10^(5)J

Ratio = 0.38

C) Max height = 52.7m

Explanation:

A) We are given;

m = 50kg

r = 4m

ω = 300 revs/min = 300 x 0.1047 = 31.4 rads/s

The formula for rotational kinetic energy is given as;

KE_rot= (1/2)Iω²

Where I is moment of inertia.

Now, I = mr²/3

But since it has 4 blades, thus,

I = 4mr²/3 = 4 x 50 x 4²/3 = 1067 kg. m²

Thus, KE_rot= (1/2)(1067)(31.4)² = 5.26 x 10^(5) J

B) The formula for translational kinetic energy is given by;

KE_trans = (1/2)mv²

We are given velocity as 20 m/s

Thus,

KE_trans = (1/2)(50)(20)² = 2 x 10^(5)J

To compare this to the rotational kinetic energy, we'll take the ratio. Thus; = KE_trans/KE_rot = 2 x 10^(5)J/5.26 x 10^(5)J = 0.38

C) At maximum height,

KE_rot = PE_gravity

Thus, 5.26 x 10^(5)J = mgh

Where m is the load it carries;

5.26 x 10^(5)J = 1000 x 9.8 x h

So, h = [5.26 x 10^(5)]/(9.8 x 1000) = 52.7m
