A bicycle is moving from rest with a constant acceleration of 3 m/s^2 calculate the final velocity of the car if the distance moves is 6

When you see distant streetlights through smog, they look dimmer and redder than they do normally. but when you see the same streetlights through fog or falling snow, they look dimmer but not redder. use your knowledge of the interstellar medium to discuss the relative sizes of the particles in smog, fog, and snowstorms compared to the wavelength of light.

Are good conductors of heat also good conductors of electricity? explain your answer.

The velocity of sound wave in air at 35°c is 353m/s, calculate the velocity of sound at 46°c
