Answer:
C
Explanation:
light can travel in a vacuum Anne the sped varies
<span>a. In the process of induction, metal objects are positive because electrons are pushed out of the object to the earth. The mass of the object decreases by an amount equal to the mass of the electrons leaving the metal object.</span>
b. <span>During the induction process, electrons are drawn from the earth to the object, so that the metal object becomes negative. <span>The mass of the object increases by an amount equal to the mass of "excess" electrons dragged onto the object.</span></span>
Average speed = Distance ÷ Time
Distance = 38 m + 1/2 of 38 m = 38 + 19 = 57 m
Time = 9 + 1.8 = 10.8 s
Average speed = 57/10.8 = 5.277 m/s
Average Velocity = Displacement ÷ Time
Displacement = 19m
Time = 9 + 1.8 = 10.8 s
Average velocity = 1.759 m/s
Distance and time, distance because that's how far and time because that's how long
Answer:
Atelectasis
Explanation:
Atelectasis is defined as the partial or completely collapsion of lungs, it is caused because of the collapse of tiny sacs of lungs or with the possibility, that these space is filled by the alveolar fluid.
Atelectasis is the condition in which the surface area of the alveolar is collapse, this can be caused due to the absence of surfactants. This condition will result in decrease or reduction of gas exchange.
