If a box weighing 520 n is hung from a spring whose constant is 650 n/m, how many centimeters will the spring stretch?

The spring stretched by 80 cm.

Explanation:

Force exerted bu the box = 520N

Spring constant = k= 650 N/m

Meter by which spring stretched = x meters

Spring constant formula:

The spring is stretched by 80 cm.

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
