As electrons move through the conductor, some collide with atoms, other electrons, or impurities in the metal. It is these collisions that cause resistance. The molecular makeup of a substance determines the number of collisions, or amount of resistance, to electron flow.
Answer:
5 Km/h
Explanation:
From the question given above, the following data were obtained:
Distance travelled = 10 Km
Time = 2 hours
Speed =?
Speed is simply defined as the distance travelled per unit time. Mathematically, it can be represented as:
Speed = distance travelled /time.
With the above formula, we can obtain the speed at which the duck is travelling as follow:
Distance travelled = 10 Km
Time = 2 hours
Speed =?
Speed = distance travelled /time.
Speed = 10 / 2
Speed = 5 Km/h
Thus, the duck is travelling at a speed of 5 Km/h
Answer: the correct option is D (17m).
Explanation: The farthest distance at which a typical "nearsighted" frog can see clearly in air is 17m.
Graduated cylinder is your answer
<span>We can find the east component of the velocity.
v_east = 6 m/s + (6 m/s) (cos (45))
v_east = 6 m/s + 4.24 m/s
v_east = 10.24 m/s
We can find the north component of the velocity.
v_north = 6 m/s + (6 m/s) (sin (45))
v_north = 6 m/s + 4.24 m/s
v_north = 10.24 m/s
We can find the magnitude of the velocity.
v = sqrt { (v_east)^2 + (v_north)^2}
v = sqrt { (10.24 m/s)^2 + (10.24 m/s)^2}
v = 14.5 m/s
We can find the angle theta north of east.
tan(theta) = 10.24 / 10.24
theta = arctan (1)
theta = 45
Note that this angle is directly northeast.
The magnitude of the velocity is 14.5 m/s and the box is moving directly to the northeast.</span>
