A block of mass 2.0kg resting on a smooth horizontal plane is acted
upon simultaneously by two forces 10N due north and 10N due east.
The magnitude of the acceleration produce by the force on the block.
A manometer wire of lenght 60 cm is maintained under
a tension of value 20V and an a.c is passed through
the wire. If the density of the wire is 4000kgm^(−3) and it
diamerter is 2mm. Calculate the frequency of the a.c
good morning!!!!
we have f(x)=x^2 +2x g(x)=−2x^2 −3x+2
and d(m)=mx+2m
1)determine the coordonate of M_1 and M_2
intersection points respectively of (Cf) and d(m)
or(Cg) and d(m)
Let A be a subset of {0;1;∙∙∙;1997}
containing more than 1000 elements.
Prove that A contains either a power
of 2 or two distinct integers whose
sum is a power of 2.
