Answer:

Explanation:

Given light with frequencies of  5.5 x 10¹⁴ Hz, 7 x  10¹⁴ Hz and 8 x  10¹⁴ Hz

we now, \lambda = \dfrac{c}{\nu}

now

1)   \lambda_1 =\dfrac{3\times 10^8}{5.5\times 10^{14}}

                      = 545.45 nm

2)   \lambda_2 = \dfrac{3\times 10^8}{7\times 10^{14}}

                      = 428.57 nm

3)   \lambda_3 = \dfrac{3\times 10^8}{8\times 10^{14}}

                      =  375 nm

the color related to wavelength are

545.45 nm - green

428.57 nm - blue

375 nm - violet

A +12 μC charge and -8 μC charge are 4 cm apart. Find the magnitude and direction of the E-field at the point midway between t
Natasha_Volkova [10]

Answer:

Explanation:

Given

Charge of first Particle q_1=+12\ \mu C

Charge of second Particle q_2=-8\ \mu C

distance between them d=4\ cm

k=9\times 10^{9}

magnetic field due to first charge at mid-way between two charged particles is

E_1=\frac{kq_1}{r^2}

r=\frac{d}{2}=\frac{4}{2}=2\ cm

E_1=\frac{9\times 10^9\times 12\times 10^{-6}}{(2\times 10^{-2})^2}

E_1=27\times 10^7\ N/C (away from it)

Electric field due to q_2=-8\ \mu C

E_2=\frac{kq_2}{r^2}

E_2=-\frac{9\times 10^9\times 8\times 10^{-6}}{(2\times 10^{-2})^2}

E_2=-18\times 10^7\ N/C(towards it)

E_{net}=E_1+E_2

E_{net}=9\times 10^7\ N/C(away from first charge)

A bald eagle is flying to the left with a speed of 34 meters
Shtirlitz [24]

Answer:

the speed after 3 seconds is 10 m/s

Explanation:

The computation of the speed is shown below:

As we know that

V = U  + at

Here,

U = 34 m/s

a =  - 8 m/s²

t = 3 Sec

V = velocity after 3 sec

V  = 34 + (-8)3

 = 34 - 24

 V = 10 m/s

Hence, the speed after 3 seconds is 10 m/s

The Iceberg Kid, infamous for imposing a deep freeze on whoever disagrees with him, discovers that in his advanced teenaged year
Mademuasel [1]

Answer:

7.24 Ω

Explanation:

Power = energy / time = 195 J / 9.81 = 19.88 W

and power = V² / R

R  resistance = 12 V²  / 19.88 W  = 7.24 Ω
