Two particles a and b are initially at distance d apart. they start moving simultaneously at velocity v and u such that a always move towards b and b moves along fixed straight line which is perpendicular to initial direction of motion of a. then particles will meet after time a. (vd)/(v^2-u^2)b. (ud)/(u^2-v^2)c. d/(v^2+u^2)^1/2 d. vd/(v^2+u^2)

Wavelength,frequency,and energy are related.what happens to a wave as it’s wavelength gets shorter?

It is reasonable to assume that the bulk modulus of blood is about the same as that of water (2.2 gpa). as one goes deeper and deeper in the ocean, the pressure increases by 10000 pa for every meter below the surface. if a diver goes down 80.0 m in the ocean, by how much does each cubic centimeter of her blood change in volume? give the answer in cubic centimeters (actually one cubic centimeter equals one milliliter).

Wavelength of 125 meters is moving at a speed of 10 m/s. what is it's frequency?
