Srivastava’s Srivastava’s MOTION IN ONE DIMENSION 1. A particle is projected vertically upwards with a velocity 20 m s1 from the top of the tower of height 100 m. Determine the time it takes to reach the ground. Answer: t 2 1 6 sec. A particle is dropped from the top of the tower of height h. At the same instant another particle is projected vertically upwards from the bottom of the tower with such a velocity that it will be able to just reach the top of the tower. When and at what height from ground

emotions‚ hunger and thirst. Our spinal cord extends several types of nerve fibers from the brain acts like a switching and relay terminal for the peripheral nervous system as is stated in Mosby’s Dictionary. The 12 pairs of cranial nerves emerge directly from the brain Sensory nerves and motor nerves of the peripheral system leave the spinal cord separately between the vertebrae but unite to form 31 pairs of spinal nerves containing sensory fibers and motor fibers. More than 10 billion neurons

The vagus nerve is the tenth of the twelve brain nerves. The vagus nerve contributes to the feelings associated with infections such as appetite‚ fatigue and induction of disease behavior. It extends from the brainstem to the abdomen‚ with branches in the neck‚ thorax and abdomen 68. The vagus nerve is part of the autonomic nervous system‚ has efferent fibers‚ ascending signals from the brain to the peripheral organs‚ as well as afferent sensory fibers‚ and transmits information from the peripheral

Task question In my task question I am going to study why does the velocity vary downstream? To carry out this investigation we will be going to Carding Mill valley; carding mill valley is located near the border of Wales‚ North West England in Shropshire. (This can be seen on image 1) (Image 1) (Image 1) This means we are collecting primary data which is mainly so we can get accurate and reliable set of results. In order to answer the task question

consideration of the forces that cause the motion. There are four activities done in this experiment. Graphical analysis of human motion‚ where displacement vs time and velocity vs. time were graphed. Graphical analysis of motion where in the 10th seconds the total displacement is 18.75m‚ average velocity is 1.88m/s and instantaneous velocity is 3.76m/s. Reaction time where one of the normal reaction time among the group is 0.16s and the reaction time while someone is distracting the member is 0.30s‚ and

The cardiac conduction system of the heart consists of specialized muscle cells that generate and send rhythmic electrical impulses to the myocardium in order for the heart to contract (Cardiac Conduction System‚ 2016). When there is the normal rhythm of the heart it is called sinus rhythm and any deviation from sinus rhythm is called an arrhythmia (Saladin‚ 2012). Electrocardiograms (ECG) record the electrical impulses and help determine when there are any abnormalities in the way the heart functions

Relative Velocity and Riverboat Problems On occasion objects move within a medium that is moving with respect to an observer. For example‚ an airplane usually encounters a wind - air that is moving with respect to an observer on the ground below. As another example‚ a motorboat in a river is moving amidst a river current - water that is moving with respect to an observer on dry land. In such instances as this‚ the magnitude of the velocity of the moving object (whether it be a plane or a motorboat)
