Answer:
positive or zero
Explanation:
if you say the amount can be accumulated, then the slope should be positive
if the amount can't be accumulated , the slope should be zero
<h2>Answer: Kitty Hawk, North Carolina
</h2>
The Wright brothers, Wilbur and Orville, were pioneers of aviation, since they flew in a device heavier than air, which was inconceivable at that time.
Their first successful flight was on December 17th, 1903 in Kitty Hawk, North Carolina, which lasted only 12 seconds in which their plane (the Flyer I, with 341 kg, 6.4 m long and a wingspan of 12.3 m) traveled 37 m without touching the ground. This was achieved through the help of an external catapult that "threw" them into the air.
It should be noted that the Wright brothers only studied until high school, however, their passion for solving the problem of the human inability to fly, their perseverance and experience acquired over the years in their bicycle company, led them to reach that goal. An achievement that marked the beginning of the aviation era.
Answer:
(1) 10^−2 m
Explanation:
The diameter of the tire of an automobile is generally expressed in centimetres; we can say that the diameter of a tire is generally about
d = 20 cm (20 centimetres)
Now we have to verify which option is closest to this value. To do that, we have to keep in mind the equivalence between metres and centimetres; in fact, we have:
This means that we can rewrite the diameter of the tire of a car as
By comparing it with the given options, we see that the closest option is
(1) 10^−2 m
which is therefore the correct answer.
Explanation:
Physical quantities are usually designated as either vector or scalar quantities.
There are several fundamental quantities know out there that makes definition of the world possible. Derived quantities are obtained from these fundamental quantities.
- A vector quantity expresses a quantity that shows both magnitude and direction.
- With a vector, you know the amount or quantity of measurement taken and the directional attribute.
- A scalar quantity is a quantity that shows magnitude but no direction.
- For example velocity is a vector and speed is a scalar. If a body moves at 10m/s due east, that is a vector.
