<span>1200 meters is less than 1 kilometer
</span>is false
Answer:
A) 
Explanation:
Since a = g - bv,
We can substitute a = dv/dt into the equation.
Then, the equation will be like dv/dt = g - bv.
So we got first order differential equation.
As known, v = 0 at t = 0, and v = g/b at t = ∞.
Since
⇒ 
So take the integral of both side.

Since for t=0, v = 0 ⇒ 

Answer:
by being calculated <em>like duh</em>
Explanation:
We will start from the period definition to find the relationship between the perioricity and the length. After finding the relationship between the two lengths and periods we will proceed to calculate the length two with the loss of the period, that is

Therefore the period is proportional to the square root of the length

Then



The period
is equivalent to the seconds that a day has, that is 86400 seconds while period two will be the seconds that have one day less the loss of 16 consecutive announced in the statement therefore,


The total change in the lenght is



Therefore the pendulum should be adjust in 
Answer:
<em>Technician B is correct by saying that the larger diameter (i.e the conductor's diameter), the less resistance it has.</em>
<em></em>
Explanation:
According to the law of electrical resistance, the resistance of a metallic conductor is proportional to the length of the conductor, but inversely proportional to the cross-sectional area of the conductor.

where R is the resistance of the conductor.
p is the intrinsic resistivity of the material with which the conductor is made.
l is the length of the conductor.
A is the cross-sectional area of the conductor.
This law simply means that if we increase the length of a conductor, or reduce the area, the electrical resistance of the conductor will increase, and vice versa.
<em>Technician B is correct by saying that the larger diameter (i.e the conductor's diameter), the less resistance it has.</em>
This is because the area of the conductor is proportional to the cross-sectional area. And the larger the cross-sectional area of a conductor, the lesser its resistance will be.
