Physics
David is driving a steady 21.0m/s when he passes Tina, who is sitting in her car at rest. Tina begins to accelerate at a steady 2.50m/s2 at the instant when David passes. How far does Tina drive before passing David? What is her speed as she passes him?

physics
A sprinter can accelerate with constant acceleration for 2.10s before reaching top speed. He can run the 100-meter dash in 10 s. What is his speed as he crosses the finish line?

physics
two wires A and B have Youngsmodlii in the ratio of length's is 1:2 and ratio of length's is 1:1 .Under the application of same stress the rato of elongations is ---- ans 1.)2:1

physics
when tension 'F' is applied the elongation produced in uniform wire of length l,radius r is e; when the tension 2F is applied the elongation produced in another uniform wire of length 2l and radius 2r made of same material is ans: 1.)1.0 e

physics
a wire whose cross-sectional area is 4mm^2 is stretched by 0.1 mm by a certain load.if a similar wire double the area of cross-section is under the same load,then then elongation would be ans: 1)0.05mm

physics
when the metal sphere is suspended at the end of a meal wire its extension is 0.4mm. If another metal sphere of the same material with its radius half as the previous is suspended then extension would be ans: 1)0.05mm

physics
a metallic ring of radius 'r' and cross sectional area is fitted into an wooden circular disc of radius R (R greater than r).If he young's modulus of the material of the ring is Y, the fore with which the metal ring expands is : ans: 1.AY(R-r)/r

physics
a string of cross section 2 cm^2 is doubled in length by the application of a longitudinal force 2*10^5dynes.the young"s modulus is: 1.10^5 dyne/cm^2

physics
an aluminium rod has a breaking strain 0.2%.The minimum cross section area of he rd in m^2 in order to support a load of 10^4N is if young's modulus is 7*10^9 N/m^2 ans: 1.) 7.1*10^-4

physics
if a stress is numerically equal to young's modulus the elongation will be ans: 1.)equal to the original length. but how?

physics
there are two wires of same material.their radii and length are both in the ratio 1:2.if the extensions produced are equal, what is the ratio of the load ? ans: 1)1:2
