Monochromatic light falls on two very narrow slits 0.047 mm apart. Successive fringes on a screen 6.60 m away are 8.9 cm apart n

Svet_ta [14]

Answer::

$\lambda = 634 nm$

$f = 4.73 *10^{14} \ Hz$

Explanation:

From the question we are told that

The distance of separation is $d = 0.047 \ mm = 0.047 *10^{-3} \ m$

The distance of the screen is $D = 6.60 \ m$

The width of the fringe is $y = 8.9 \ cm = 0.089 \ m$

Generally the width of the width of the fringes is mathematically represented as

$y = \frac{\lambda * D }{d }$

=> $\lambda = \frac{y * d }{D }$

=> $\lambda = \frac{ 0.089 * (0.047 *10^{-3}) }{6.60 }$

=> $\lambda = 634 *10^{-9}$

=> $\lambda = 634 nm$

Generally the speed of light is mathematically represented as

$c = f * \lambda$

=> $f= \frac{ c}{\lambda }$

=> $f= \frac{ 3.0 *10^{8}}{634 *10^{-9}}$

=> $f = 4.73 *10^{14} \ Hz$

A 0.40-μF capacitor is connected to a 5.0-V battery. How much charge is on each plate of the capacitor? Express your answer usin

weqwewe [10]

Answer:

$Q=2.0\times10^{-6}C$

Explanation:

The equation of charge on the capacitor given its capacitance and a voltage applied to it is Q=CV.

Our capacitance is expressed in <em>microfarads</em>, where micro stands for $\times10^{-6}$ , so in S.I. we sill have:

$Q=CV=(0.4\times10^{-6}F)(5V)=0.000002C=2.0\times10^{-6}C$

Where the results has been expresed with <em>two significant figures</em>.

What do thermal energy and electrical energy have in common

Lubov Fominskaja [6]

Answer:

you can write some points its an explanation

and similarities. or common

Explanation:

Thermal energy refers to the energy contained within a system that is responsible for its temperature. Heat is the flow of thermal energy. A whole branch of physics, thermodynamics, deals with how heat is transferred between different systems and how work is done in the process (see the 1ˢᵗ law of thermodynamics).

The faster the atoms or molecules move, the more heat or thermal energy they have. ... A hair straightener turns the electrical energy from a wall outlet into heat (thermal energy). 4. As electricity runs through the filaments in a space heater, the electrical energy is converted into heat (thermal energy).
