Explanation:
The relationship of the speed of sound, its frequency, and wavelength is the same as for all waves: vw = fλ, where vw is the speed of sound, f is its frequency, and λ is its wavelength.
Answer:
Explanation:
As we know that system of two gliders are moving on frictionless track
so momentum conservation is applied on it
So we will have
so we will have
now we know that collision is elastic so we have
so by solving above equations we have
Answer:
The magnification of an image is equal to the ratio of the image height to the object height.
Relax. Everything's under control.
If you use up all your exclamation points now, then

(1.4 x 10⁵ newton/coulomb) x (-1.6 x 10⁻¹⁹ coulomb)
= (1.4 x 10⁵ x -1.6 x 10⁻¹⁹) newton-coulomb/coulomb
= - (1.4 x 1.6) x 10⁵⁻¹⁹ newton
= - 2.24 x 10⁻¹⁴ newton
Answer:
Mass of the larger object
