what is the maximum distance we can shoot a dart,from ground level provided our toy dart gun gives a maximum initial velocity of
mestny [16]

Answer:

R = v^2 sin 2 theta / g

The range provides the distance a projectile can travel

R(max) = v^2 / g    if theta = 45 deg

R = 2.7^2 / 9.8 = .74 m

Photoelectrons are observed when a metal is illuminated by light with a wavelength less than 383 nm. What is the metal's work fu
Ulleksa [173]

Answer:

Work function of the metal is 3.24 eV.                                    

Explanation:

It is given that,

Wavelength, \lambda=383\times 10^{-9}\ m

Let W is the work function of the metal. It is given by using Einstein's photoelectric effect equation. It is given by :

W=\dfrac{hc}{\lambda}

W=\dfrac{6.63\times 10^{-34}\times 3\times 10^8}{383\times 10^{-9}}

W=5.193\times 10^{-19}\ J

Since, 1\ eV=1.6\times 10^{-19}\ J

So, W = 3.24 eV

So, the work function of the metal is 3.24 eV. Hence, this is the required solution.
