Apply the following settings and answer the questions a. Remove damping (or slide to none)
b. Check the stopwatch box to activate the timer
c. Attach the 100g mass slowly and record the initial position of this spring-mass system.
d. Now stretch additional 10cm and let it be moving up and down so that it constitute SHM

1. Record the time it takes for 20 complete oscillations and calculate the period (the time for one complete cycle.

Time (t) = s, Period (T) = s

2. Using the spring constant found in step 1 and the 100g mass, calculate the period of this SHM.

the best answer for these questions would be:

1.            c. is smaller

2.            d) concrete operational

3.            b) interaction with the environment – the children interact with their environment can them learn more.

4.            a) parents who reason openly with children can limit a child’s cognitive ability.

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction 

D.) a wheel barrow, due to the fact that where the weight is in the middle, the fulcrum is at the wheel, and the input force is at the other end
