Tutorial – Work‚ Energy (Assume the acceleration due to gravity‚ g = 9.81 m/s2 ) 1. Calculate the work done when a force of 40 N pushes an object a distance of 500 m in the same direction as the force. 2. Calculate the work done when a mass is lifted vertically by a crane to a height of 5 m‚ the force required to lift the mass being 98 N. 3. A spring‚ initially in a relaxed state‚ is extended by 100 mm. Determine the work done by using a work diagram if the spring requires

QUESTION( Conservation of Energy) 1. Missy Diwater‚ the former platform diver for the Ringling Brother’s Circus had a kinetic energy of 15 000 J just prior to hitting the bucket of water. If Missy’s mass is 50 kg‚ then what is her speed? Solution: According to energy conservation‚ the kinetic energy at the bottom of the dive (15‚000J) is equal to her gravitational potential energy before the dive. We can use this fact to find her dive height: PE = mgh h = PE/mg = 15‚000J / (50kg)(9.81m/s²)

What is an action potential? To put it simply‚ it is a message that is sent down the nervous line. The message is written and is sent from the central nervous system. That message is addressed to muscles or glands. This essay will explain what happens before‚ during‚ and after an interneuron action potential. To accurately define an action potential‚ it is part of the incredible course of events that occur during the firing of a neuron. When a neuron is not firing signals‚ the interior of the
