A) There is no kinetic energy lost in the collision. b) Kinetic energy is not conserved due to the action of internal
friction.

c) Kinetic energy is not conserved due to the action of external
friction

d) All kinetic energy is lost in the collision.

answer: decibel

explanation:

wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.

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.

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop
