The one that's completely submerged is displacing more water, so the buoyant force on it is greater.
Mirrors don't cause refraction.
A convex mirror could cause parallel rays to REFLECT away from each other.
If you are working with electricity most people will measure it in watts.
So, A. watts is your best answer.
Hope I helped! ^w^
Answer:
B on Edge 2020
She can change the arrows so they show current traveling in opposite directions on the sides of the loop.
Explanation:
Just took the test haha
Answer:
v=0.94 m/s
Explanation:
Given that
M= 5.67 kg
k= 150 N/m
m=1 kg
μ = 0.45
The maximum acceleration of upper block can be μ g.
a= μ g ( g = 10 m/s²)
The maximum acceleration of system will ω²X.
ω = natural frequency
X=maximum displacement
For top stop slipping
μ g =ω²X
We know for spring mass system natural frequency given as

By putting the values

ω = 4.47 rad/s
μ g =ω²X
By putting the values
0.45 x 10 = 4.47² X
X = 0.2 m
From energy conservation


150 x 0.2²=6.67 v²
v=0.94 m/s
This is the maximum speed of system.
