It has a neutral charge which means it is equal.
<span>Correct Answer: Option B
The complete question is:
A train starts from rest and accelerates uniformly until it has traveled 3.7 km and acquired a velocity of 30m/s The train then moves at a constant velocity of 30m/s for 410 s. The train then slows down uniformly at 0.065m/s</span>²<span> until it reaches a halt. What distance does the train travel while it is slowing down?
We have the initial velocity u = 30 m/s
Final velocity = v = 0
Acceleration = a = -0.065 m/s</span>²
The negative sign indicates that the train is slowing down.
Using the 3rd equation of motion, we can find the distance covered by the train:
2as = v² - u²
2(-0.065)S = 0 -30²
⇒
S = 6923 meters = 6.9 km
Answer:
what does it mean for a plate to subduct?
Explanation:
Subduction is a geological process in which the oceanic lithosphere is recycled into the Earth's mantle at convergent boundaries. Where the oceanic lithosphere of a tectonic plate converges with the less dense lithosphere of a second plate, the heavier plate dives beneath the second plate and sinks into the mantle.
Global warming is the unusually rapid increase in Earth's average surface temperature over the past century primarily due to the greenhouse gases released as people burn fossil fuels. ... Temperatures are certain to go up further. Despite ups and downs from year to year, global average surface temperature is rising.
Answer:
at the same time as the light object
Explanation:
vacuum is a region with a gaseous pressure much less than atmospheric pressure.
In a vacuum, gravity causes all objects to fall at the same rate. The mass of the object does not matter. If I drop for example a heavy stone and a light stone, air will make the light stone fall more slowly. But if there were no air, they would fall at the same rate.
So, When an object falls with air resistance, both its rate of fall and speed change during its motion. When an object falls in a vacuum, there is no air resistance because there is no air in a vacuum.
