can anyonr give me 20 mathematical or physics formulas with radical sign?

Question

with examples pls

Answer 1

No, do your own work.

Answer 2

relatively you are able to desire to respond to question b to respond to question a: you probably did no longer outline what letter replaced into such as what yet your equations seem o.k.. a=acceleration of the diver v=velocity of the diver y=place of the diver those al matter on time g=gravtational consistent v0=preliminary velicity of the diver y0=preliminary place of your diver So a(t)=-g => v(t)=-g*t+v0 => y(t)=-a million/2*g*t²+v0*t+x0 Supposing that the diver does not bounce yet shall we himself fall v0=0 and from the textual content fabric x0=50 Now you desire to appreciate how lots is "t" whilst y=0 (touches the exterior) so y(t)=0 and y(t)=-a million/2*g*t²+0*t+50=-a million/2*g*t²+50 =>0=-a million/2*g*t²+50 =>50=a million/2*g*t² =>50*2/g=t² =>the two t=-sqrt(50*2/g) or t=sqrt(50*2/g) the two are mathematically spectacular yet bodily the negatice time isn't attainable for this reason so t=sqrt(50*2/g) supposing that g=9.80 one => t=3.19sec supposing that g=10 => t=3.16sec now which you recognize the time at which the diver hits the water and because you recognize that v(t)=-g*t+v0=-g*t supposing that g=9.80 one => t=3.19sec => v=9.80 one*3.19=31.3m/s supposing that g=10 => t=3.16sec => v=10*3.sixteen=31.6m/s do no longer neglect the contraptions

Answer 3

The "quadratic formula" and the "Lorenz foreshortening" are two. Look them up in Google.
