An aptitude test is a systematic means of testing a job candidate's abilities to perform specific tasks and react to a range of different situations. The tests each have a standardised method of administration and scoring. The results are quantified and compared with all other test takers.
Answer:
T = 300 N
Explanation:
As we know that the painter is standing at the middle of the scaffold
So here the two ropes will exert same tension on the scaffold
So we will have
also we know
so we will have
so tension is half of the weight in both the strings
So it is
T = 300 N
Answer:
In summary, it is safe to handle this voltage with dry hands because the current value that you pass through the body is smaller than its underestimated sensitivity.
Explanation:
The current flowing through your system is described by Ohm's law
V = I R
where I is the current, V the voltage and R the resistance
in this case three barateras are taken in series giving a total voltage of V = 4.5 V the typical resistance values of dry skin is R = 1000 000Ohm and the resinification of wet skin is R = 100000 ohm
let's calculate the current flowing
I = V / R
I = 4.5 / 1000000
I = 4.5 10⁻⁶ A
this is the current with dry hands, we see that much less than the value that allows to feel a painful response by the body
If the skin is
I = 4,5 / 100,000
I = 4.5 10⁻⁵ A
This value is small, but it is close to the pain threshold, but it is in the range of slight discomfort.
In summary, it is safe to handle this voltage with dry hands because the current value that you pass through the body is smaller than its underestimated sensitivity.
Answer:
DIRECTION
Explanation:
the answer of the blank will be DIRECTION
As the signal is far ahead so driver can make the decision of what he have to do either he can change direction or he can be on his same path.
But for that driver has to change his or her speed.
so, from the statement given the blank will be filled with DIRECTION
