The minimum average speed it must have in the second half of the event in order to qualify is 414.7 km/h.
<h3>
What is average speed?</h3>
The average speed of an object is the ratio of total distance traveled by the object to the total time of motion of the object.
<h3>Total time taken by the car during the entire race</h3>
time = distance/average speed
time = (1.41 km) / (278 km/h)
time = 0.0051 hr
The car travels the first half of the race, d (¹/₂ x 1410 m) at 210 km/h;
d = 705 m = 0.705 km
t1 = 0.705/210
t1 = 0.0034 hr
<h3>time for the second half</h3>
t2 = 0.0051 - 0.0034 hr
t2 = 0.0017 hr
<h3>minimum average speed of the second half</h3>
v = d/t
v = 0.705 km / 0.0017 hr
v = 414.7 km/hr
Thus, the minimum average speed it must have in the second half of the event in order to qualify is 414.7 km/h.

That is right because base*length is how you get the height
Answer:
Explanation:
Since the fly accumulated a positive charge of +73pC, it must have lost an equal number of negative charge of -73pC to the surface (because the housefly was neutral to begin with).
Therefore, to answer our question we have to ask ourselves <em>how many electrons combine to make -73pC of charge? </em>
The answer is since one electron carries a charge of 
, the number 
of electrons that make up -73pC 
are
Thus, the housefly lost about 456 million electrons to the surface!
If y<span>ou are going to invent a new device that people can use instead of a microwave oven to warm up leftovers, the type of electromagnetic wave that would be most useful to investigate would probably be infrared waves, because these kinds of waves are associated with heat. </span>
Mechanical waves need material stuff to travel through.
They cannot travel through vacuum.
That's why we can't hear the explosions on the sun.
That's also why astronauts standing on the moon or working outside the Space Station have to use radio to talk to each other, even if they're only a few inches apart. There's no air between them, or any other material stuff. So sound can't travel between them.
