A bolck of mass 5 kg lies on rough horizontal surface .Whena horizontal force of 24.5 N is applied to the block , at just starts sliding while 19.6N is enough to keep it sliding at uniform velocity find i) coefficient of static friction
ii)coefficient of kinetic energy
Find also the acceleration of the block when at rest is acted by a force of 24 N and a negligible impulse is imparted.​

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.

explanation:

answer: the correct answer for the fill in the blank is rods.

rods are the specialized photoreceptor cells that are present in the retina of human eye. they are responsible for vision in the night time ( also called scotopic vision). they have very low visual acuity and color distinguishing ability.

as they are responsible for vision in night time, therefore they are found predominantly in the nocturnal animals.
