Ablock-spring system consists of a spring with constant k = 465 n/m attached to a 1.00 kg block on a frictionless surface. the block is pulled 5.70 cm from equilibrium and released from rest. for the resulting oscillation, find the amplitude, angular frequency, frequency, and period. what is the maximum value of the block's velocity and acceleration? hint (a) amplitude (in m) m (b) angular frequency (in rad/s) rad/s (c) frequency (in hz) hz (d) period (in s) s (e) maximum velocity (in m/s) m/s (f) maximum acceleration (in m/s2) m/s2

the largest known star in the universe is uy scuti, a hypergiant with a radius around 1,700 times larger than the

answer: at 24 february, 2014 the population gets twice of its initial population.

explanation:

since we have given that

the population for alpha city, t years after january 1, 2004 is given as

first we find out the initial population, i.e. t=0,

so, our quadratic equation becomes,

according to question, we have said that if the population has twice its initial population, then it becomes

so, time taken to reach this above mentioned population is given by

now, we know that time can't be negative so, we take t=9.149 years.

hence, at 24 february, 2014 the population gets twice of its initial population.

i don't understand. explain it clearly

god i hope this !
