Answer:
The distance is
Explanation:
From the question we are told that
The wavelength of the light source is
The distance from a pin hole is
The diameter of the pin hole is
Generally the distance which the light source need to be in order for their diffraction patterns to be resolved by Rayleigh's criterion is
mathematically represented as
substituting values
Answer: B - complimenting others on good plays
Explanation: Reading the first words sort of give it away when staying positive you compliment, not criticize, confront angrily, or refuse.
Answer:
Explanation:
As we know that average velocity is defined as the ratio of total displacement of the object and its time interval.
so here we can say
now we know that in one complete revolution the total displacement of the tip of the seconds hand is zero
because it will have same position after one complete revolution from where it starts
so here we can say that the average velocity will be zero
Answer:
Explanation:
Given
For first case
launch angle
at highest point
For second case
at highest Point velocity is
as there is no acceleration in x direction therefore horizontal velocity is same
