Answer:
Δx = 2.5 x 10⁻³ m = 2.5 mm
Explanation:
The distance between two consecutive fringes, also known as fringe spacing, in Young's Double Slit Experiment, is given as follows:
Δx = λL/d
where,
Δx = distance between consecutive fringes = ?
λ = wavelength of light = 500 nm = 5 x 10⁻⁷ m
L = Distance between slits and screen = 5 m
d = slit separation = 1 mm = 1 x 10⁻³ m
Therefore,
Δx = (5 x 10⁻⁷ m)(5 m)/(1 x 10⁻³ m)
<u>Δx = 2.5 x 10⁻³ m = 2.5 mm</u>
Answer: option B. 45°
Explanation:
A body thrown at an angle from horizontal undergoes a projectile motion. The maximum horizontal displacement means the maximum range covered. The range is given by:
where v is the initial velocity, is angle of the projectile and g is the acceleration due to gravity.
For maximum range, sin 2θ = 1
2θ = sin⁻¹ 1 = 90°
θ = 90°/2 = 45°
Thus, the projectile undergoes maximum horizontal displacement at angle of 45°. Correct option is B.
Answer:
The velocity of the cart when it reaches its greatest y coordinates is 10.135m/s
Explanation:Vx=0
0=6.8m/s+(6.2m/s^2)t
t=6.8/6.2
t= 1.1secs
Vy= 12m/s +(-1.7m/s^2 )t
Vy=12 +(-1.7×1.1)
Vy=12 -1.865)
Vy=10.135m/s
From the wording of the question, I'm suspecting that you have ...
... either a piece of equipment or else a computer program named "myDAQ",
... an inductor to play with and measure, either in your hand or on the screen.
I have none of these advantages.
In fact, nobody reading this on Brainly has.
It's like if I asked you to write an equation that can be solved to find the total amount of money in all five of my pockets right now.
Newton’s second law is that the acceleration of an object is directly related to the net force and inversely related to its mass. Acceleration of an object depends on two things, force and mass.
