Answer: I'll help you when i end school
Explanation: ok
Answer:
NO
Explanation:
The angular position of a diffraction null is given by
Asinθ=m λ=m c/f
Given that A is the slit width,
and m is an integer.
The wavelength of the second null satisfies
λ= A sinθ₁/2
of which if there were distinct third null it will satisfy
sinθ₂=3λ/A= 3* sin 45/2
λ=(3*0.7071)/2
λ=2.121/2
λ=1.060
Of which 1.060 is greater than 1
Hello there.
<span>Petrol tankers have a metal chain hanging that touches the ground. Can you say why?

Those chains are
Called Grounding chain.
Why do Petrol tankers have them not sure.
Hope my answer helped!
Answer:
a) The velocity is 2.94m/s
b) 0.441
Explanation:
a) Assume gravity is 9.8m/s^2
Use the equation below to solve for the velocity at 0.30 seconds
,
vf =unknown velocity vi= initial velocity vi=0m/s a= 9.8m/s^2 t=0.30seconds
Step 1: Substitute the variables with the knowns
Step 2: Solve
b)
Use the equation below to solve for the displacement at 0.30 seconds
Step 1: Substitute the same variables with the knowns
Note that vi*t=0 as vi=0m/s
Step 2: Solve
x=0.441m
