Answer:
D. Fluorine.
Explanation:
For an atom to accept an electron, from another atom, it must have high electron affinity compared to the other elements.
Large atoms then to have high electron affinity compared to smaller atoms and most large atoms are non metals while elements with smaller atomic radius are metals. Tin(Sn), Arsenic(As) are metals and they have lower electrons affinity compared to Sulfur (S) and Fluorine (F).
Fluorine have a high electron affinity than Sulfur and hence has a larger atomic radius and can easily draw most of the electrons shared between the two atoms.
There's a trend to electron affinity and I.e it increases down the period and decreases down the group.
Most group (VII)A elements form electrovalent compounds due to their tendency to pull the shared electron towards them(high electron affinity) compared to Sulfur (a group VIA) element.
By the use of "Solar cells" or "Solar panel", we can trap solar energy in silicon/germanium rods, then we can convert in into electricity too.
Hope this helps!
Answer : D) Circuit A
This circuit is the only circuit where it is not complete, having and open spot towards the bottom of it, making it and open circuit.
The answer is false because the laser doest burn the images onto the paper.
Answer:
The time for final 15 cm of the jump equals 0.1423 seconds.
Explanation:
The initial velocity required by the basketball player to be able to jump 76 cm can be found using the third equation of kinematics as

where
'v' is the final velocity of the player
'u' is the initial velocity of the player
'a' is acceleration due to gravity
's' is the height the player jumps
Since the final velocity at the maximum height should be 0 thus applying the values in the above equation we get

Now the veocity of the palyer after he cover'sthe initial 61 cm of his journey can be similarly found as

Thus the time for the final 15 cm of the jump can be found by the first equation of kinematics as

where symbols have the usual meaning
Applying the given values we get
