krok68 [10]

Answer:

3.5434 eV

Explanation:

For a particle with kinetic energy E and mass m , the wavelength associated is given by the following relation,

$\lambda=\frac{h}{\sqrt{2mE} }$

E = $\frac{h^2}{2m\lambda^2}$

Putting the values we get

E = $\frac{(6.6\times(10^{-34})^2}{2\times9.1\times10^{-31\times(1.5\times10^{-9})^2}}$

=1.063 x 10⁻²¹ J

= .0066 eV.

Energy of¹light in terms of eV

= 1244 / 350 = 3.55 eV.

Work function = 3.55 - 0.0066 = 3.5434 eV.

OleMash [197]

Answer:

204.5 m

Explanation:

a = v \ t

t = v \ a

t = 31 \ 4.7 = 6.6s

v = d \ t

d = v * t

d = 31 * 6.6

d= 204.5 meters

A vector has components Ax = 52.0 m and Ay = 41.0 m. Find: (a) The length of the vector A.

vredina [299]

Answer:

Part a)

A = 66.2 m

Part b)

Angle = 38.35 degree

Explanation:

Part a)

Length of the vector is the magnitude of the vector

here we know that

$A_x = 52.0 m$

$A_y = 41.0 m$

now we have

$A = \sqrt{A_x^2 + A_y^2}$

$A = \sqrt{52^2 + 41^2}$

$A = 66.2 m$

Part b)

Angle made by the vector is given as

$tan\theta = \frac{A_y}{A_x}$

$tan\theta = \frac{41}{52}$

$\theta = 38.25 degree$
