When your car is broken down on the side of the road, you should make your vehicle as _____ as possible. A. visible B. comfortable C. cooled D. loud
Answer:
A
Explanation:
If you're car brokebroke down and you may want people to see it so you can get help right away in case you are hurt.
The car broken down on the road, must be made more and more visible. Thus, option A is correct.
What is the importance of driver consciousness in broken car case?The driver is responsible for his actions on the road, and thereby was found with the awareness to the traffic safety. In case the car is broken and not made visible, it may lead to the number of road accidents.
Thus, the car must be made visible on the side of the road in case it is broken down to avoid the accidents and raise help. Thus, option A is correct.

1)Why is a change in polarity useful in welding?
2)explain the function of Ae7013 welding rod.
3)list and explain 4 factors you need to observe while stick welding to make a good “consistent” bead.
Someone help please ASAP
Answer 1:
Choosing the right polarity probably affects the quality and strength of the weld. This is why the changes in the polarity is useful in welding.
Answer 2:
There are different sizes of welding rods available in the market. the majorly used sizes are namely 6010, 6011, 6012, 6013, 7014, 7024 and 7018. The 7013 rod is used for welding low and mild alloy steel.
Answer 3:
The 4 major factors involved in stick welding to make good “consistent” bead are as follows,
Current setting - Determining whether DC positive, DC negative, or AC should be set up in the machine chosen.Length of arc - Do not let the arc stutter. The exact lenth differs with the application and electrode.Speed of travel - The speed should help in maintaining the arc in leading 1/3 of the weld pool.Manipulation of electrode - Practice, observe and develop the technique that would result the best.7.

Find the amount of energy (Q) required to raise the temperature of the water in kilo joules (KJ).
Given mass of water m = 2kg = 2000g.
Temperature difference ΔΤ = T2 – T1 = 60 °C – 25 °C = 35 °C .
Specific heat of water = 4.18 J/g* °C .
Therefore, Q =
kilo joules.
Amount of energy required = 292.6 kJ
Explanation:
Amount of energy required is given by the equation ,
Q = m × C ×ΔT
where m is the mass of the water = 2000 g
C is the specific heat of water = 4.18 J/g°C
ΔT = Temperature difference = 60 - 25 = 35 °C
Applying these values in the above equation, we will get,
Q = 2000 g × 4.18 J/g°C × 35°C
= 292600 J
When joule is divided by 1000 we will get the amount of energy in kJ.
[tex]$ Q = \frac{292600}{1000} = 292.6 kJ[/tex]
So the energy required to raise the temperature of the water is 292.6 kJ.

1. Consider the steady flow in a water pipe joint shown in the diagram. The areas are:
A1=0.2 m², A2=0.2 m², and Az=0.15 m². In addition, Fluid is lost out of a hole at
section 4, estimated at a rate of 0.1m/s. The average speed at section 1 and 3 are
Vi=5m/s and V3=12m/s, respectively. Find the velocity at section 2.
Answer:
-4.5 m/s
Explanation:
Assuming steady and incompressible flow and uniform properties at each section
[tex]V_1A_1+V_2A_2+A_3V_3+Q_4=0[/tex]
Here V is velocity of flow and A is area, Q is flow rate out of the leak, subscript 1-4 represent different sections
At the surface, is negative hence the equation above will be
[tex]-V_1A_1+V_2A_2+A_3V_3+Q_4=0[/tex]
Making the subject of the formula then
[tex]V_2=\frac {V_1A_1-A_3V_3-Q_4}{A_2}[/tex]
Substituting the given values then
[tex]V_2=\frac {(5\times 0.2)-(12\times 0.15)-0.1}{0.2}=-4.5 m/s\\V_2=-4.5m/s[/tex]
An ice hockey player is skating on an ice rink. The rink has a coefficient of kinetic friction of roughly 0.1. If the normal force on the hockey player is 800. N, what is the frictional force acting on the hockey player?
Answer:
The frictional force acting on the Hockey player = 80 N.
Explanation:
Given,
coefficient of kinetic friction = 0.1
Normal force on the hockey player = 800 N.
Frictional force acting on the hockey player = ?
Frictional force acting on the hockey player ca be calculated using the formula,
Frictional force = coefficient of kinetic friction x Normal force
substituting the values,
Frictional force = 0.1 x 800 = 80 Newtons.
Therefore, Frictional force acting on the Hockey player = 80 N.

A sailboat is operating under sail at night. Which of these lights should be used?
orange masthead light
blue sternlight
yellow masthead light
white sternlight
Answer:
White Stern light
Explanation:
According to boating regulations, navigation lights must be used for safety purposes when operating water vessels especially during the night.
The boating regulations for operating sailboats, specify that a white stern light must be used during hours from sunset to sun rise. This is to indicate the presence of the sea craft on the ocean, as well as its direction.
A stern light is a white light placed as closely as practical at the stern shining constantly. It covers an angle of 135 degrees, and helps show the direction of the boat.
The lights should be used is white sternlight.
What lights should be used in a sailboat at night?A sailboat is operating under sail at night is known to be one where the operator of that sailboat is said to be operating under sails at darkness and so their sidelights should be (red - green) and stern light (white).
When they are said to be less than 20 meters in length, the three lights can be use altogether at or near the top of the mast.
