Answer;
At the top of group 17
Explanation;
Reactivity in chemistry deals with whether something will react with another substance. The reactivity of an element can be predicted based on its location on the periodic table.
The most reactive nonmetal is fluorine. Fluorine is a halogen, which is Group 17 on the periodic table, and the halogens are the most reactive nonmetals. This is because they all have one empty space in their valence electron shells. Of the halogens, fluorine's empty space is closest to the positively charged nucleus. This means it pulls harder on another atom's electrons to fill that empty space.
Answer:
A.C → Alternating current.
D.C → Direct current
Explanation:
A.C is an abbreviation for Alternating current.
Alternating current is a type of current that flows sinusoidally or current that changes direction with time.
D.C is an abbreviation for Direct current.
This type of current flows only in one direction, i.e it doesn't change direction with time.
A rectifier can be used to convert A.C to D.C, allowing it to flow in one direction.
Answer:
true
Explanation:
Yes, it is true.
As the wattage is more than the prescribed wattage, it becomes overheated.
It will be 9.55 m/s.
as the velocity vector will be
6.38 in vertical direction pointing downwards after 1 second
and the horizontal will be 4.86
the angle between them is 35°
thus using parallelogram law of vector addition
you get
v^2 = 6.38*6.38+4.86*4.86+2(6.38)(4.86)cos35°
v^2 = 40.7044+23.61+26.92
v^2 = 91.24
v = 9.55 m/s
