Ur asnwers B my friend have an amazing day:)
There’s force of friction/ drag that slows down a moving object, there’s also gravity pulling the wagon down which would help slow it down. Hope this helps good luck.
Answer:
10.0 m
Explanation:
Since there is no amplitude at the point of the swimmer, we have destructive interference.
So, the path difference ΔL = L₂ - L₁ where L₁ = swimmer's shorter distance from one generator = 9.0 m and L₂ = swimmer's longer distance from the other generator = 14.0 m. ΔL = 14.0 m - 9.0 m = 5.0 m
Also, since we have destructive interference, ΔL = (n + 1/2)λ where n = number of wavelengths and λ = wavelength of waves
For maximum wavelength, n = 0
So, ΔL = (n + 1/2)λ
ΔL = (0 + 1/2)λ
ΔL = λ/2
λ/2 = ΔL
λ = 2ΔL
λ = 2 × 5.0 m
λ = 10.0 m
So, the longest wavelength that will produce this interference pattern is λ = 10.0 m
Answer:
I strongly feel its 1.
Explanation:
the expectancy theory of motivation is basically getting an reward for a great accomplishment so 1 would make the most sense in this question, lmk if its wrong
Answer:
Explanation:
From Newton's 2nd Law, we have 
. Using this, we can find the acceleration of the object:
.
Now that we've found the block's acceleration, we can use the following kinematics equation to find its final velocity after 2 seconds:
*Assumption: The block is initially at rest and has a initial velocity of zero. Otherwise, the question is unsolvable.
