a body travels 200 cm in the first two second and 220 cm in the next 4 seconds.what will be the velocity at the seventh second from the start.
What will be value of molarity and strength %w/v respectively 30V H2O2 solution
the answer is 60 degrees
The general equation of such cosine function is:y=acos(x-phasedifference), y=displacement a=amplitude x=angular displacement =(angular velocity)*time =(2pi/time period)*time Therefore, the equation can be written as: y=2cos[x-(pi/4)]..........(a) or,y=2cos[(2pi/pi)*t-(pi/4)] o...
x^6+3x^3+2=0 It can also be written as: (x^3)^2+3(x^3)+2=0...........(1) Let a=(x^3), then we may rewrite equation (1) as: a^2+3a+2=0 or,a^2+a+2a+2=0 or,a(a+1)+2(a+1)=0 or,(a+1)(a+2)=0 either,a=-1 or,a=-2 that is (x^3)=-1 or (x^3)=-2 Therefore, x=-1 or x=cube root of -2 this i...
Thanks that was really helpful. But the solution to the limit problem is still not clear to me.
a)in how many different ways can 8 exam papers be arranged in a line so that the best and worst papers are not together? b)in how many ways can 9 balls be divided equally among 3 students? c)There are 10 true-false questions. By how many ways can they be answered? d)lim(x tend...
If R1 and R2 be the two resistances connected in (a)series, then equivalent resistance=R1+R2 (b)parallel, then equivalent resistance=(R1*R2)/(R1+R2)
