A progressive wave equation is given as y = 0.2 sin ( 200nt - Tx/15) where t is in second and both x and y in cm. Determine: 1. the velocity of the wave,
ii. the maximum velocity of the particles, iii. the velocity at P, a distance of 45 cm from the source at time = 0.05s.

This is what i found on google “what happens to the bond angle when you add or remove an electron domain? the bond angle decreases as you add domains 5. can you force the atoms into new configurations by pushing atoms around? note: we can think of a bond or a lone pair of electrons as a “domain” of electrons.” i hope this you

Pe = 1/2k(x)^2  and .05n/m = .05x10^-9m = x 

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction
