Neuromuscular reaction time can be influenced by a number of different factors. Design an experiment where neuromuscular reaction time and the factors that influence it are tested among different individuals. This can be tested by measuring how quickly a person can grasp a falling meter stick.

When fat comes in contact with sodium hydroxide, it produces soap and glycerin. determine whether this is a physical change or a chemical change. explain your answer

Atrain departs from its station at a constant acceleration of 5 m/s. what is the speed of the train at the end of 20s?

The energy released by a chemical reaction can be measured using a calorimeter. when barium hydroxide octahydrate crystals are reacted with dry ammonium chloride inside of a coffee cup calorimeter, the temperature of the 18.00 g of water in the calorimeter decreases from 30.0°c to 8.0°c. the equation for calculating energy absorbed or released by a reaction is: where q is the energy released or absorbed, m is the mass of water in the calorimeter, cp is the specific heat of water, and δt is the observed temperature change. if the specific heat of liquid water is 4.19 j/g·°c, how much energy was absorbed by the reaction?
