Answer:
The number of interference fringes is 
Explanation:
From the question we are told that
The wavelength is 
The distance of separation is 
The order of maxima is m = 5
The condition for constructive interference is
=> ![\theta = sin^{-1} [\frac{5 * 433 *10^{-9}}{ 6 *10^{-6}} ]](https://tex.z-dn.net/?f=%5Ctheta%20%20%3D%20%20sin%5E%7B-1%7D%20%5B%5Cfrac%7B5%20%20%2A%20%20433%20%2A10%5E%7B-9%7D%7D%7B%206%20%2A10%5E%7B-6%7D%7D%20%5D)
=> 
So at
=>
The forces on the mass on the table are balanced because it moves at constant speed. The force to the right is 2mg, the force to the left must also be 2mg. The weight on the left is 1mg so the friction force on the mass on the table is also 1mg to the left.
The answer to the first question is C isotonic environment. To help me learn this I memorized that isotonic is equal hypotonic is over hydrated while hypertonic is dehydrated. And for the second question is they move from high to low so C
I think the answer may be D- mechanical
Answer:
a) horizontal range s=277671.77 m
b) time the shell is in motion 301.143 s
Explanation:
Is a parabolic movement so the velocity have two components:
°
