What happens to the distance between interference fringes if the separation between two slits is increased?
kolezko [41]

Answer:

It will decrease

Explanation:

The double-slit interference equation, which gives us the position y of a maximum on the screen (measured relative to the central position), is

y=\frac{n\lambda D}{d}

where

n is the order of the maximum

D is the distance between the slits and the screen

\lambda is the wavelength of the light

d is the separation between the two slits

From the formula, we see that y is inversely proportional to d: this means that if the separation between the slits is increased, the distance of each maximum from the central position (y) decreases, therefore the distance between the interference fringes will decrease.

Help me in this please help me!
Eddi Din [679]

Answer:

1. A

2. C

3. A

4. B

Explanation:

A conductor allows electric current to pass through it. Hence, when conductors are connected in a closed circuit, current flows.

All the resistors in Q2 are connected in series. In a series connection, the current across all the resistors is the same.

In a battery, chemical energy is converted to electrical energy by chemical reactions.

When a new resistor is connected in parallel to a circuit the current increases accordingly.

Michael is biking on a trail and is accelerating at a rate of 1.2 m/s/s for 15 seconds. He began this part of his ride with a ve
Serhud [2]

Answer:

Michael's final velocity is 19.62 m/s.    

Explanation:            

We can find the final velocity of Michael by using the following kinematic equation:

v_{f} = v_{0} + at   (1)    

Where:

v_{f}: is the final velocity =?

v_{0}: is the initial velocity = 1.62 m/s

a: is the acceleration = 1.2 m/s²

t: is the time = 15 s

By entering the above values into equation (1) we have:

v_{f} = 1.62 m/s + 1.2 m/s^{2}*15 s

v_{f} = 19.62 m/s

Therefore, Michael's final velocity is 19.62 m/s.

I hope it helps you!

A spherical helium filled balloon (B) with a hanging passenger cage being held by a single vertical cable (C) attached to Earth
Gre4nikov [31]

Answer:

The tension is  T  = 4326.7 \  N

Explanation:

From the question we are told that

   The  total mass is  m  =  200 \  kg

    The  radius is r = 5 \  m

     The  density of air is  \rho_a  =  1.225 \ kg/m^3

Generally the upward  force acting on the balloon is mathematically represented as

        F_N  =   T  + mg

=>     (\rho_a  *  V  *  g ) =   T  + mg

=>   T  =  (\rho_a  * V  *  g   )  - mg

Here V is the volume  of the spherical helium filled balloon which is mathematically represented as

      V  =  \frac{4}{3}  * \pi r^3

=>   V  =  \frac{4}{3}  * 3.142 *(5)^3

=>   V  = 523.67\  m^3

So

    T  = (1.225 *  523.67*  9.8 ) -  200 *  9.8

   T  = 4326.7 \  N
