1 a vector lying along x aixs is its y component ?Explain 2 if a vector A lies in xy plane and angle with x axis the its y component will be
3 If | A+B | = | A -B | angle b/w the vectors is
4 if the resulant of 2 vectors each magntide F is also of magnitude F, the angle b/w them will be
5if the vectors A and B are magnitude 4 anmd 3cm making of 30 and 40 degree respectively withs x axis their saclar prouct will be
a 0 cm2
b 6 cm2
c 18 cm2
d 21 cm2
kindly explain all questions.

These models show the electron structures of two different nonmetal elements. which element is likely more reactive, and why? element 1 is more reactive because it has fewer electron shells and is toward the top of its group on the periodic table. element 1 is more reactive because it has more electrons in its valence shell and is farther to the right on the periodic table. element 2 is more reactive because it does not have a valence shell close to the nucleus, so it will attract electrons. element 2 is more reactive because it does not have a full valence shell, so it will attract electrons.

Orange juice has a lower or higher viscosity than chocolate syrup

In a voltaic cell, electrons flow from the (positive/negative) to the (positive/negative) terminal.
