Answer:
A reserved power is a power specifically reserved to the states. Powers include setting up local governments and determining the speed limit. A concurrent power is a power that is given to both the states and the federal government.

Explanation:
given,
mass of the cart 1, m₁ = 310 g
speed of car 1 , v₁ = 1.25 m/s
mass of cart 2, m₂ = 260 g
speed of cart 2, v₂ = -1.33 m/s
speed of center of mass
Hence, speed of center of mass of the system is equal to 0.0732 m/s
Answer:
part (a) 
Part (b) 
Explanation:
Given,
- Mass of the larger disk =
- Mass of the smaller disk =
- Radius of the larger disk =
- Radius of the smaller disk =
- Mass of the block = M = 1.60 kg
Both the disks are welded together, therefore total moment of inertia of the both disks are the summation of the individual moment of inertia of the disks.
part (a)
Given that a block of mass m which is hanging with the smaller disk,
Let 'T' be 'a' be the tension in the string and acceleration of the block.
From the free body diagram of the smaller block,
From the pulley,
From the equation (1) and (2),
part (b)
Above expression for the acceleration of the block is only depended on the radius of the pulley.
Radius of the larger pulley = 
Let 
be the acceleration of the block while connecting to the larger pulley.
To be honest, the picture is so far above that I can't see it at all.
But reading the information in the question's statement, I'd say
the blank should be filled in so that it says:

Explanation:
a) the capacitance is given of a plate capacitor is given by:
C = \epsilon_0*(A/d)
Where \epsilon_0 is a constant that represents the insulator between the plates (in this case air, \epsilon_0 = 8.84*10^(-12) F/m), A is the plate's area and d is the distance between the plates. So we have:
The plates are squares so their area is given by:
A = L^2 = 0.19^2 = 0.0361 m^2
C = 8.84*10^(-12)*(0.0361/0.0077) = 8.84*10^(-12) * 4.6883 = 41.444*10^(-12) F
b) The charge on the plates is given by the product of the capacitance by the voltage applied to it:
Q = C*V = 41.444*10^(-12)*120 = 4973.361 * 10^(-12) C = 4.973 * 10^(-9) C
c) The electric field on a capacitor is given by:
E = Q/(A*\epsilon_0) = [4.973*10^(-9)]/[0.0361*8.84*10^(-12)]
E = [4.973*10^(-9)]/[0.3191*10^(-12)] = 15.58*10^(3) V/m
d) The energy stored on the capacitor is given by:
W = 0.5*(C*V^2) = 0.5*[41.444*10^(-12) * (120)^2] = 298396.8*10^(-12) = 0.298 * 10 ^6 J
