(eopt)s. Find the power dissipated in a 25 r heater<br>connected to a 220V outer.

Alex Ar [27]

Answer:

P = 1936 W

Explanation:

Given that,

Voltage, V = 220 V

The resistance of the heater, R = 25 ohms

We need to find the power dissipated in the heater. We know that the power dissipated by the electric appliances is given by :

$P=\dfrac{V^2}{R}\\\\P=\dfrac{(220)^2}{25}\\\\P=1936\ W$

So, the required power is equal to 1936 W.

If the electron has a speed equal to 9.10 x 10^6 m/s, what is its wavelength?

Fudgin [204]

Answer:

$\lambda=8.006\times 10^{-11}\ m$

Explanation:

Given that,

The speed of an electron, $v=9.1\times 10^6\ m/s$

We need to find the wavelength of this electron. It can be calculated using De -broglie wavelength concept as :

$\lambda=\dfrac{h}{mv}$

h is the Planck's constant

$\lambda=\dfrac{6.63\times 10^{-34}}{9.1\times 10^{-31}\times 9.1\times 10^6}$

$\lambda=8.006\times 10^{-11}\ m$

So, the wavelength of the electron is $8.006\times 10^{-11}\ m$ . Hence, this is the required solution.
