during the last trial also. E.g. the normal heart rate was 20 H.B. per 15.38 seconds while the heart rate after adrenaline was added was 20 H.B. per 6.70 seconds. This proves that adrenaline excites the neurotransmitters and causes the heart rate to speed up. But this data is not precise because during the lab‚ the heart could not be clearly seen in each of the Daphnia. For example‚ after measuring the heart rate of one daphnia‚ you had to add more adrenaline around the Daphnia to measure how adrenaline

With the above materials students were able to run the four experiments. For experiment students turned on the Xplorer GLX‚ put the motion detector at the end of the silver track‚ and aimed the black variable speed cart away from the motion detector.

Jimmy took 8 hrs to drive his Civic from KL to Kota Bharu which was about 400 km away. What was the average speed of Jimmy in km/h? Why‚ in this case was the term average speed used over velocity? 3.

Instead of starting at zero (where he was in A)‚ the man started at -8 under the tree. His speed was increasing at a constant rate so the graph shows him moving in a positive direction from the tree. Explanation for graph’s appearance - after actually performing the activity. Since he is speeding up at a constant rate‚ then his velocity is steadily

intersection. On January 22‚ 2011‚ Felicia Harris was on her way home from work. She was driving East on Highway 43 approaching the intersection of Highway 43 and Sharon Road. Upon reaching the intersection she was driving at a high rate of speed ignoring the speed suggestion signs. By the time she began to apply her brakes it was too late‚ she was into the curve of the road and over compensated to gain control and veered off the road crashing head on into a tree. Unfortunately Felicia did not survive

set a speed limit of 55 miles per hour on federal highways‚ more people will die than if Congress sets the speed limit at 45 miles per hour. In my opinion‚ this is a very true statement. I think if the congress was to lower the speed limit in many areas‚ they will be prolonging many lives. Vehicles are dangerous because of their ability to reach high speeds. People get injured in crashes via vehicles almost every day‚ and yet Congress still fails to resolve this issue by lowering the speed limit

for speed attitude I can’t help but want to go faster. I give one last tug at my helmet to make sure it’s on tight before I go into my tuck because one mistake without the proper safety equipment at the speeds I’m about to encounter can cause me my brain. I bend my knees and crouch close to my board. I hide my back leg behind my front one by tucking in my knee behind the other so that aerodynamics can help me go faster. I lean forward in front of the board and keep my arms behind me. The speed and
