Answer:
A. Knowledge and awareness: Knowing how to recognize that an environment has dangers that must be avoided
B Ability: Be realistic in telling a co-worker that his or her ability is not sufficient to promote safe work. Example: an employee prevents a trainee from working with acids, since the trainee does not have enough capacity to handle these elements safely.
C. State of Mind: Professionals must always be aware that all team members are in emotional and psychological conditions of sufficient quality to carry out work safely. Example: a truck driver who received sad news over the phone, decides to park the truck and only drive again when he is in a better state of mind.
D. Environmental conditions: Analyze possible environmental hazards and avoid them. Example: electricians, avoid manipulating power cords in stern environments in moments of rain, as there is a risk of electroshock.

very far from earth (at r=[infinity]), a spacecraft has run out of fuel and its kinetic energy is zero. if only the gravitational force of the earth were to act on it (i.e., neglect the forces from the sun and other solar system objects), the spacecraft would eventually crash into the earth. the mass of the earth is me and its radius is re. neglect air resistance throughout this problem, since the spacecraft is primarily moving through the near vacuum of space.
By considering the conservation of energy, the speed V of the spacecraft when it eventually crash into the earth and its distance from the center of the earth is r are 11172.6 m/s and 3294.6 m/s respectively.
Given that, r is at infinity when a spacecraft has run out of fuel and its kinetic energy is zero. if only the gravitational force of the earth were to act on the spacecraft would eventually crash into the earth.
Where
Mass of the earth [tex]m_{e}[/tex] = 5.97 × [tex]10^{24}[/tex] kg
Radius of the earth [tex]R_{e}[/tex] = 6.38 × [tex]10^{6}[/tex] m
G = 6.67 x [tex]10^{-11}[/tex]N[tex]m^{2}kg^{-2}[/tex]
a.) Since the spacecraft is primarily moving through the near vacuum of space, the speed V of the spacecraft when it eventually crash into the earth can be calculated by considering the conservation of energy.
The total initial energy = total final energy.
[tex]E_{i} = E_{f}[/tex]
[tex]K.E_{i}[/tex] + [tex]U_{i}[/tex] = [tex]K.E_{f}[/tex] + [tex]U_{f}[/tex]
where [tex]K.E_{i}[/tex] = 0
-G[tex]m_{e}[/tex]m/(r + [tex]R_{e}[/tex]) = 1/2m[tex]V^{2}[/tex] + ( -G[tex]m_{e}[/tex]m)/[tex]R_{e}[/tex]
mass of the spacecraft will cancel out
G[tex]m_{e}[/tex]/(r + [tex]R_{e}[/tex]) = 1/2[tex]V^{2}[/tex] + ( -G[tex]m_{e}[/tex])/[tex]R_{e}[/tex]
G[tex]m_{e}[/tex]/(r + [tex]R_{e}[/tex]) = 0 since r is at infinity.
0 = 1/2[tex]V^{2}[/tex] + ( -G[tex]m_{e}[/tex])/[tex]R_{e}[/tex]
Substitute all the parameters into the equation above.
0 = 0.5[tex]V^{2}[/tex] + ( -6.67 x [tex]10^{-11}[/tex] x 5.97 x [tex]10^{24}[/tex] )/6.38 x [tex]10^{6}[/tex]
0.5[tex]V^{2}[/tex] = 62,413,636.36
[tex]V^{2}[/tex] = 62,413,636.36 / 0.5
[tex]V^{2}[/tex] = 124,827,272.7
V = [tex]\sqrt{124,827,272.7}[/tex]
V = 11172.6 m/s
b.) Given that the distance from the earth r = x([tex]R_{e}[/tex])
That is,
r = 11.5 x 6.38 x [tex]10^{6}[/tex]
r = 73,370,000 m
To find the spacecraft's speed when its distance from the center of the earth is r, we will use the same formula. That is,
[tex]K.E_{i}[/tex] + [tex]U_{i}[/tex] = [tex]K.E_{f}[/tex] + [tex]U_{f}[/tex]
0 = 1/2[tex]V^{2}[/tex] + ( -G[tex]m_{e}[/tex])/r
Substitute all the parameters into the formula
0 = 0.5[tex]V^{2}[/tex] + ( -6.67 x [tex]10^{-11}[/tex] x 5.97 x [tex]10^{24}[/tex] )/ 73,370,000
0.5[tex]V^{2}[/tex] = 5427272.727
[tex]V^{2}[/tex] = 10854545.45
V = [tex]\sqrt{10854545.45}[/tex]
V = 3294.6 m/s
Therefore, the speed V of the spacecraft when it eventually crash into the earth and its distance from the center of the earth is r are 11172.6 m/s and
3294.6 m/s respectively.

C major is simply known to be one of the most user key signatures found in music. It is known to have its key signature to have no flats and no sharps keys.
The C major scale is known to have the scale of zero sharps or flats. It does not have any key signature and it makes it easier to identify any music in the key of C major.
For one to be able to play the C major scale ascending, one must start with the root note C and play the notes in order: C - D - E - F - G - A - B - C. Then, one can either go right back down the scale of B - A - G- F- E - D.

The barry family invited 100 relatives to their christmas party. 90 guests had italian heritage, 80 had german heritage and 75 had swiss heritage. What is the minimum number of people who claimed ancestry from all three heritages?.
Answer:
45
Explanation:
The minimum number of people who claimed ancestry from all three heritages is : 45
Given that there are 100 relatives
let's assume that 1 relative = 1 room
100 relatives = 100 rooms
Number of relatives with Italian heritage = 90
Number of relatives with German heritage = 80
Number of relatives with swiss heritage = 75
Step 1 :
Fill up the first 90 rooms with Italian heritage relatives
Fill up the remaining 10 rooms with 10 Relatives with German heritage
Step 2 :
Distribute the remaining 70 relatives with German heritage into 70 rooms out of the 90 rooms already occupied by the relatives with Italian heritage
Step 3:
Distribute the 75 relatives with swiss heritage into the 20 rooms occupied by Italian heritage relatives only and 45 rooms occupied by both German and Italian relatives and into the 10 rooms occupied by the German heritage relatives
Therefore we can conclude that the minimum number of people who claimed ancestry from all three heritages is : 45

Traveling with the current, a boat travels a distance 1. 5 times greater than it does when traveling against the current in the same amount of time. What is the speed of the boat in still water if the speed of the current is 1. 5 mph?.
The speed of the boat in still water if the speed of the current is 1.5mph is equal to 7.5mph.
Solution:We have to define the terms in this question
We have Sc = Speed of the current = 1.5mph
We have Sb = Speed of the boat in the still water
We have this equation:
Sb + Sc = 1.5(Sb - Sc)
Sb + Sc = 1.5Sb - 1.5Sc
We have to collect the like terms
Sb - 1.5Sb = -1.5Sc - Sc
-0.5Sb = -2.5Sc
We divide through this equation by the value of Sb
[tex]\frac{-0.5Sb}{-0.5} =\frac{-2.5Sc}{-0.5}[/tex]
Sb = 5Sc
Given that the speed of current Sc = 1.5. then
Sb = 5*1.5
Sb = 7.5
In conclusion, the speed of the boat in still water at 1.5mph = 7.5mph

The security system in a house has two units that set off an alarm when motion is detected. Neither one is entirely reliable, but one or both always go off when there is motion anywhere in the house. Suppose that for motion in a certain location, the probability that detector a goes off and detector b does not go off is 0. 25, and the probability that detector a does not go off is 0. 35. What is the probability that detector b goes off?.
The probability that detector B goes off is 0.75
The probability of an event is known to be the likelihood or chance for an event to occur.
From the given information let consider:
A = the time when detector A goes off, andB = the time when detector B goes offSince one or both of them always goes off, then:
P(A or B) = 1∴
Their complements will be zero, i.e.
P(A' and B') = 0Similarly, we are given that:
P(A and B') = 0.25Then;
P(A') = 0.35∴
The set probability for A will be:
P(A) = 1 - P(A')
P(A) = 1 - 0.35
P(A) = 0.65
Finally, the probability that detector B goes off can be computed as:
P(B) = P(A) P(B|A) +P(A') P(B|A')
P(B) = P(A) (1 - P(B|A')) + P(A') (1 - P(B'|A')
[tex]\mathbf{P(B) = P(A) (1-\dfrac{P(A \ and \ B')}{P(A)}) +P(A') (1 - \dfrac{P(A' \ and B')}{P(A')})}[/tex]
