Two blocks, each with a mass $m$ = 0.188 kg, can slide without friction on a horizontal surface. initially, block 1 is in motion with a speed $v$ = 1.76 m/s; block 2 is at rest. when block 1 collides with block 2, a spring bumper on block 1 is compressed. maximum compression of the spring occurs when the two blocks move with the same speed, $v$/2 = 0.880 m/s. if the maximum compression of the spring is 1.70 cm, what is its force constant?

change tension

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.

the closer the planet is to the sun, the larger the gravity

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
