Answer:
single bit error: 10pdouble bit error: 45p²triple bit error: 120p³Explanation:
The probability of n bits being in error is 10Cn × p^n, where ...
10Cn = 10!/(n!(10-n!))
10C1 = 10
10C2 = 45
10C3 = 120
This is the product of the probability that n bits can be in error and the number of ways that n bits can be chosen from the 10 in the word.
n = 1: 10p
n = 2: 45p²
n = 3: 120p³

The reference OSHA standard requires several important characteristics of a PFAS. The employer must ensure that personal fall arrest systems (PFAs) must:
a. Limit the maximum arresting force on the employee to 1,800 pounds (8 kN). The figure used above must be based on the use of a full body harness.
Maximum arresting force is the highest amount of force that the fall protection system and the individual attached to the system will face as gotten by the deceleration device.OSHA regulations gives the system performance criteria for a personal fall arrest system.
From the above, we can therefore say that The reference OSHA standard requires several important characteristics of personal fall arrest systems (PFAs) as employers must reduce the maximum arresting force on the employee to 1,800 pounds (8 kN) using full body harness.

A two-stage air compressor operates at steady state, compressing 10 m3 /min of air from 100 kPa, 300 K, to 1200 kPa. An intercooler between the two stages cools the air to 300 K at a constant pressure of 350 kPa. The compression processes are isentropic. Calculate the power required to run the compressor, in kW, and compare the result to the power required for isentropic compression from the same inlet state to the same final pressure.
check photos (answer)
Comparing this to the actual power required for the two-stage compressor (242.6 kW), we can see that the actual power required is significantly higher.
What is work done?Work done is the amount of energy transferred to or from a system as a result of a force acting on it over a distance.
To solve this problem, we can use the following steps:
Step 1: Determine the state points of the air at various stages of the compression process.
Stage 1: Inlet state = State 1
P1 = 100 kPa, T1 = 300 K, V1 = 10 m³/min
Stage 2: After the first stage of compression = State 2
P2 = 1200 kPa, T2 = ? (isentropic compression)
Stage 3: After intercooling = State 3
P3 = 350 kPa, T3 = 300 K, V3 = V2
Stage 4: After the second stage of compression = State 4
P4 = 1200 kPa, T4 = ? (isentropic compression)
Step 2: Calculate the temperature and specific volume at states 2 and 4 using the isentropic compression process.
For an isentropic compression process, we have:
(P2/P1)^((γ-1)/γ) = T2/T1
(P4/P3)^((γ-1)/γ) = T4/T3
where γ is the ratio of specific heats for air, which is approximately 1.4.
Solving for T2 and T4, we get:
T2 = T1*(P2/P1)^((γ-1)/γ) = 300*(1200/100)^((1.4-1)/1.4) = 742.6 K
T4 = T3*(P4/P3)^((γ-1)/γ) = 300*(1200/350)^((1.4-1)/1.4) = 892.5 K
Next, we can use the ideal gas law to calculate the specific volume of air at states 2 and 4:
V2 = V1*(P1/P2)(T2/T1) = 10(100/1200)(742.6/300) = 0.1867 m³/kg
V4 = V3(P3/P4)(T4/T3) = 10(350/1200)*(892.5/300) = 0.2604 m³/kg
Step 3: Calculate the work done in each stage of the compressor.
For an isentropic compression process, the work done can be calculated using the following equation:
W = (mCp)(T2-T1) = (mCp)(T4-T3)
where m is the mass flow rate of air, which can be calculated using the specific volume and inlet volumetric flow rate:
m = V1/(v160) = 10/(0.831460) = 0.2016 kg/s
Cp is the specific heat at constant pressure for air, which is approximately 1.005 kJ/kg-K.
Thus, the work done in each stage of the compressor is:
W1 = (0.20161.005)(742.6-300) = 77.2 kW
W2 = (0.20161.005)(892.5-300) = 116.9 kW
The total work done by the compressor is:
W_total = W1 + W2 = 77.2 + 116.9 = 194.1 kW
Step 4: Calculate the power required to run the compressor.
The power required to run the compressor can be calculated using the following equation:
Power = W_total/η
where η is the compressor efficiency.
We are not given the efficiency, but for a two-stage compressor, a reasonable estimate for η is reasonable estimate for the efficiency of a two-stage compressor is around 75-85%. Therefore, we can assume η = 0.8.
Using this efficiency value, the power required to run the compressor is:
Power = W_total/η = 194.1/0.8 = 242.6 kW
Step 5: Compare the result to the power required for isentropic compression from the same inlet state to the same final pressure.
For isentropic compression from the same inlet state to the same final pressure, the work done can be calculated using the following equation:
W = (mCp)(T2-T1) = (mCp)(T4-T3) = (m*Cp)*ΔT
where ΔT = T2-T1 = T4-T3 = 442.5 K
Thus, the work done for isentropic compression is: W_iso = (0.2016*1.005)*442.5 = 89.1 kW

Amends the FMVSS on air brake systems to improve the stopping distance performance of truck tractors. The rule requires the vast majority of new heavy truck tractors to achieve a 30 percent reduction in stopping distance compared to currently required levels. For these heavy truck tractors (approximately 99 percent of the fleet), the amended standard requires those vehicles to stop in not more than 250 feet when loaded to their gross vehicle weight rating (GVWR) and tested at a speed of 60 miles per hour (mph). For a small number of very heavy severe service tractors, the stopping distance requirement will be 310 feet under these same conditions. In addition, this final rule requires that all heavy truck tractors must stop within 235 feet when loaded to their “lightly loaded vehicle weight” (LLVW).
