Grade 12th passWave Motion

1)how brownian motion can be increased in a gas?
2)what are thermodynamic functions?give examples
3)is it possible to have damped oscillations when a system is at resonance?
4)could we ever construct a simple pendulum?explain
5)why roads are banked at hill stations?
6)prove that grad r =r/r
7)the average speed of air molecules in a room is the order of speed of sound.what is their average velocity?

kindly someone help me out as soon as possible

Brownian motion is the Random Motion of Particles suspended in a fluid or Gas, It can be increased by the raising the temperature of . surroundings, By increasing temperature , more particles can be intermixed , and more Brownian motion can be observed.

The fundamental thermodynamic equations follow from five primarythermodynamic definitions and describe internal energy, enthalpy, Helmholtz energy, and Gibbs energy in terms of their natural variables.

3.Yes, an oscillator with damping can vibrate at resonance with amplitude that remains constant in time.Without damping,the amplitude would increase with limit at resonance.This particular imppact is linearly relevant to the speed on oscillations.

5.If the road is banked, so that the outer edge is above the inner edge, then a portion of the normal force from the road on the tires points towards the center of the track; this fraction of the normal force can provide enough centripetal force to keep the car moving in a circle.

A particle on a speing executes shm when the particle is found at x=xmax/2 the speed of the partcle is
A)vx=vmax
B)vx=√3vmax/2
C)vx=√2vmax/2
D)vx=vmax/2
