(a)
11001.1011₂ = 1×2⁴ + 1×2³ + 1×2⁰ + 1×2 ⁻¹ + 1×2 ⁻³ + 1×2 ⁻⁴
… = 16 + 8 + 1 + 1/2 + 1/8 + 1/16
… = 411/16
(b) In base 16, we have A₁₆ = 10 and C₁₆ = 12, so
A3.C₁₆ = 10×16¹ + 3×16⁰ + 12×16 ⁻¹
… = 160 + 3 + 12/16
… = 2620/16 = 655/4
(c)
75.16₈ = 7×8¹ + 5×8⁰ + 1×8 ⁻¹ + 6×8 ⁻²
… = 56 + 5 + 1/8 + 6/64
… = 3918/64 = 1959/32
(d) B₁₆ = 11 and D₁₆ = 13, so
ABCD₁₆ = 10×16³ + 11×16² + 12×16¹ + 13×16⁰
… = 40960 + 2816 + 192 + 13
… = 43981

Answer:
B
Explanation:
A double-threaded Acme stub screw of known major diameter is used in ajack having a plain thrust collar of known mean diameter. Coefficients of running friction are estimated as 0.10 for the collar and 0.11 for the screw. Assume (1) the starting friction is about 1/3 higher than running friction and (2) the screw is not exposed to vibration.
Required:
a. Determine the pitch, lead, thread depth, mean pitch diameter, and helix angle of the screw.
b. Estimate the starting torque for raising and for lowering a 5000 lb load.
c. If the screw is lifting a 5000 lb load at the rate of 4 ft/min, what is the screw rpm? What is the efficiency of the jack under this steady-state condition?
d. Would the screw overhaul if a ball thrust bearing (of negligible friction) were used in place of the plain thrust collar.

how is a electrical resistance similar to the diameter of a pipe of water
Answer:
The resistance of the flow of charges in an electric circuit (electrical resistance) is analogous to the frictional effect between water flow through a pipe and the pipe's surface
Explanation:
In comparison to its similarity to the diameter of the pipe affects the flow of water and acts a a factor affecting resistance so are there factors affecting electrical resistance.
in an electrical circuit:
the total length of the wire is to the length of a pipe of water
the cross-sectional area of the wire is to the diameter of a pipe of water.
Thus, the cross sectional are affects the amount of electrical resistance. Wider wires have wider cross-sectional area and vice versa. Also, water will flow (i.e. current) through a wider pipe (i.e. large diameter) at a faster rate than a narrow pipe (i.e. small diameter). This is due to the lower amount of resistance offered by the wider pipe.
in the same manner, the wider the wire, the lesser the electrical resistance to the flow of elsctric charge and vice versa for thiner wires.

Propose any improvements if there are any in brake system
Improvements to brake systems are
Increase in disc radiusIncrease in caliper piston areaLine pressureThe friction coefficient between the pad and the rotorWhat is a brake system?Converts the thermal energy through friction, and the brake system takes the kinetic energy of your moving vehicle.Larger discs will permit for more brake torque as the brake pad will apply pressure at a larger radius, permitting for a higher moment.Increasing the size of the pistons means you have more area to put in a specific pressure. If the pressure remains the same and the area increases, the force applied will be increased.Push your foot harder, and the car brakes harder due to this the line pressure increases. Self-explanatory, but if you can increase the friction between the pad and the rotor, you can increase the braking torque.To learn more about the brake system refer to:

How does Brake system work
Answer:
To stop a car, the brakes have to get rid of that kinetic energy. They do so by using the force of friction to convert that kinetic energy into heat. This hydraulic system multiplies the force of your foot on the brake pedal into enough force to apply the brakes and make the car stop.
