Answer:
A. find problems that could cause a collision or breakdown
Explanation:
A pretrip inspection allows the driver to drive safely because he feels satisfied since he already had checked each and everything in the beginning. This increases the focus on driving. In addition to it there are less chances of happenings and technical faults in the vehicle. It also plays a vital role in the safety circumstances as well.
b. 1 unit
c. 75 units
d. m149 units

Answer:
introduction of new animals and crops to North America
Explanation:
Since the early 1500s, Europeans have transported old world species to their new settlements in the Western Hemisphere, as well as to other parts of the world. The manifestoes of Christopher Columbus' second and subsequent voyages, for example, mention the deliberate transportation of species considered potential crops and livestock. Global trade has grown astronomically since then, providing an opportunity for the corresponding growth of biological invasions. Consequently, biological invasions can be viewed as a predominantly post-Columbian event. Put in perspective, the movement of organisms caused by humans, accidentally or deliberately in the last 200 to 500 years, undoubtedly dwarfs in frequency and impact the movement of organisms by natural forces at any 500-year period in Earth's history.
b) change the length of the wires between transmission towers
c) not use a transformer at all
d) change the type of conducting material
e) use a step down transformer
ans d) change the type of conducting matey
For long-distance transmission of power, in order to reduce losses in the wires by driving a low current at high voltage, we should use a step-up transformer (a) .
(That's at the beginning, to step-up the voltage for long-distance transmission. And then use a step-down transformer at the end, to reduce the voltage just before we pour it into the customer's house.)
Answer:
θ = 41.8º
Explanation:
This is an internal total reflection exercise, the equation that describes this process is
sin θ = n₂ / n₁
where n₂ is the index of the incident medium and n₁ the other medium must be met n₁> n₂
θ = sin⁻¹ n₂ / n₁
let's calculate
θ = sin⁻¹ (1.00 / 1.50)
θ = 41.8º
