Answer:
yeah
Explanation:
as wavelength increases frequency decreases and it goes the same for the opposite way
Answer:to prevent serious damage when an accident occur
Explanation:to prevent serious damage when accident occur
The minimum height of the dive needed to achieve the given speed is v = 69 m/s is 242.9 m.
Given information:
The mass of peregrine falcon is, m = 480
The final speed reached by the peregrine falcon in a vertical dive is, v = 69 m/s
It is given that the falcon is diving vertically downward. It can be compared with the same situation as the free-falling object under the effect of gravity only. So, the initial velocity of the falcon will be u = 0 m/s as the motion starts with rest.
The value of the gravitational acceleration of gravity is, g = 9.80 m/s²
Now, using the third equation of motion, the minimum height required for the final speed will be,
v² - u² = 2gh
69² - 0² = 2 × 9.8 × h
h = 242.9m.
Therefore, the minimum height of the dive needed to achieve the given speed is 242.9 m.

Answer:
The spacing between the slits is 
Explanation:
From the question we are told that
The wavelength of the light is 
The distance of the slit from the screen is 
The number of bright fringe is 
The length the fringes span is 
The fringe width (i.e the distance of between two successive bright or dark fringe) is mathematically represented as
Where d is the distance between the slits
is the fringe width which can also be evaluated as
Substituting values
Making d the subject of formula in the above equation
Substituting values
