Question

What will be effect on the horizontal range of a projectile

Answer 1

Range=v2sin2A/g

Now,

v is doubled and angle remain same

=(2V)2sin2A/g 

=4v2sin2a/g

so range will become double

Chemistry

1 AS wavelwngth=h/mv

so whose mass will be bigger so wavelength will be less

so less mass is of electron is less so wavelength will be more for electron

Answer 2

in horizontal range society is classified top to bottom level
for example 1 principal 2 professor 3 pean
