Answer:
a) 152000 slugs
b) 2220000 kg or 2220 metric tons
Explanation:
A body with a weight of 4.9*10^6 lbf has a mass of
4.9*10^6 lbm * 1 lbf/lbm = 4.9*10^6 lbm
This mass value can then be converted to other mass values.
1 slug is 32.17 lbm
Therefore:
4.9*10^6 lbm * 1 slug / (32.17 lbm) = 152000 slugs
1 lb is 0.453 kg
Therefore:
4.9*10^6 lbm / (1/0.453) * kg/lbm = 2220000 kg
Answer: (A) Security regression testing
Explanation:
The security regression testing is used to prevent the re-occurring process. The regression testing is the type of the testing that intends to affirm that a program or code or application changes has not influenced existing highlights and it keeps up the agenda.
The agenda ought to be similarly identified with necessity that was concluded. By checking this both then relapse testing occurs and this won't reoccurred from next time.
The regression testing improvements groups must ensure that changes, updates and new discharges don't presents imperfections and vulnerabilities that could be misused by the people.
Answer:
Sedimentation is not a good method.
Explanation:
We need to apply Stoke laws and assume that is valid here.
So,

Replacing the values,

Here then we calculate the time,

Where x= Distance, v= velocity

To calculate the surface required we need first to calculate the volume through the volume,
So,

Then,

Here we can calculate the surface

<em>So, the requeriment of Area of tank and settlement time is huge, it's not a practical method.</em>

Incomplete question: Find the normal reaction the curved portion of the ramp exerts on the package at B if pB = 2 m, the height is 4 m
Answer: The required speed is 8.9107 m/s
The normal reaction is 99.0006 N
Explanation:
Given data:
m = 2 kg
vA = speed = 1 m/s
h = 4 m
g = gravity = 9.8 m/s²
Questions: Determine the required speed of the conveyor, vc = ?
Find the normal reaction, Nc = ?
The required speed applying the conservation of energy:

Solving for vc:

The normal reaction applying the equilibrium of forces:
