Answer:
Explanation:
Given that,
Velocity of the airplane, v = 240 m/s
Angle with horizontal,
The altitude of the plane is 2.4 km, d = 2400 m
Vertical speed of the airplane,
Horizontal speed of the airplane,
So, the equation of the projectile for the flare is given by :
On solving the above equation, we get the value of t as:
t = 13.04 seconds
Horizontal distance travelled,
d = 2710.23 m
Let is the angle with which it hits the target. So,
Hence, this is the required solution.
Answer:
β 2 = 0.02575 mm
Explanation:
given data
wavelength = 563 nm
separation distance between adjacent bright fringes = 0.0290 mm
wavelength = 500 nm
solution
we get here separation distance between adjacent bright fringes that is express as
β = ..................................1
here D is distance from plane of slit to screen
and d is slit sepation that is constant
so
β 2 =
β 2 = 0.02575 mm
