(+105) + (+80) = 185 units.
The resultant amplitude of the wave is 185 units.
Answer:
the time Joshua travels 1 mile is 12.5 min
Explanation:
Let's start by finding the distance traveled on each lap,
Let's reduce everything to the SI system
R = 400 m
d = 1 mile (1609 m / 1 mile) = 1609 m
L = 2 pi R
L = 2 pi 400
L = 2513 m
Let us form a rule of proportions if 2 turns of Julian is 3 turns Joshua, for 1 turn of Joshua how many turns Julian took
lap Julian = 2/3 turn Joshua
Let's calculate what distance is the same for both of them since they are on the same track
1 lap = 2513 m
d. Julian = 2/3 2513 m
d Julian = 1675 m distance Joshua
Let us form the last rule of three or proportions if 1609 m you travel in 12 min how long it takes to travel 1675 m
t Julian = 1675/1609 12
t = 12.5 s
Since this is the distance Joshua travels, this is the time Joshua travels 1 mile

Answer:
w = 0.808 rad / s
Explanation:
As indicated by the moment of inertia t the angular velocity of the disks we use the concept of conservation of the angular momentum, for this we define the system as formed by the two discs, therefore the torque during the crash is internal and the angular momentum is conserved
Let's write in angular momentum
Initial. Before impact
L₀ = I₁ w₁ + I₂ w₂
Final. After the rock has stuck
= (I₁ + I₂) w
The two discs are rotating in opposite directions, we consider the rotation of the first positive disc, so the angular velocity of the second is negative
L₀ =
I₁ w₁ - I₂ w₂ = (I₁ + I₂) w
w = (I₁ w₁ - I₂ w₂) / (I₁ + I₂)
Let's calculate
w = (0.47 2.0 - 0.31 1.0) / (0.47+ 0.31)
w = 0.63 / 0.78
w = 0.808 rad / s
in the direction of disc rotation 1
I believe the answer would be C.
