Write a summary paragraph discussing this experiment and the results. Use the following questions and topics to help guide the c
ontent of your paragraph. According to your data, was your hypothesis correct? (Be sure to refer to your data when answering this question.)
Summarize the conclusions that you can draw from this experiment. Use the questions above to guide your ideas.
Summarize any difficulties or problems you had in performing the experiment that might have affected the results. Describe how you might change the procedure to avoid these problems.
Give at least three examples from everyday life where an inclined plane is used to reduce the effort force needed to accomplish a task.
In this experiment, you will determine the IMA, AMA, and efficiency.
The materials for this experiment are:
a smooth board
smooth block or other object to drag up a plane
a spring scale (calibrated in newtons)
string
books or blocks to support the inclined plane
and a meter stick.
Your job is to observe the experiment and collect your own data from this demonstration.
Be ready to record your observations and data.
You will be pulling an object up an inclined plane at different inclines.
Make and record a hypothesis about how changine the slope of inclined plane will affect the efficiency.
Measure the height and length of the plane, record the measurements.
Measure the mass of the object, and record. Convert the mass from grams to newtons by dividing by 102, and record.
Now slowly and steadily pull the object up the incline with the spring scale and string kept parallel to the incline.
Record the readout on the scale.
This will be the effort force.
Now increase the slope of the incline by increasing the height.
Measure the height of the new incline.
The length of the incline remains constant.
Slowly and steadily pull the object up the incline, record the readout from the scale.
You are now ready to complete the rest of this assignment.
LOL i belive its 200 because i did this exact same thing yesterday for homework and got it right bcs i got it lol, yw btw! hahaha! good luck also, subscribe to my channel!
intensity of the light (the energy per unit area per unit time)
Explanation:
The photoflash capacitor is an electrolytic capacitor that is also used in flash cameras, professional illumination and solid-state laser supply. Their general purpose is to briefly power a high-voltage flash tube, which can be used to illuminate photographic material or to alternately pump a laser rod.
Since the flash tube requires very little time to operate, photoflash capacitors are designed to supply high discharge current pulses without excessive internal heating.
