Unit 7 Hooke's Law Lab

Loosen the retaining screw and adjust the horizontal arm to the dimple that produce the 2nd largest radius between the spinning mass and the rotating shift. Allow the spinning mass to hang straight down, without being connected to the spring. Position the pointer directly below the tip of spinning mass and secure the pointer to the base. Use the scale located on the base to determine the radius, r, of the pointer from the rotating shaft. Record this value onto Data Sheet A. The experimental uncertainty in r is estimated to be the width of the spinning mass tip – approximately 0.2 cm.

Lastly, put finger on the caliper that infront on the right hand side of the throttle and applied some force to slow down the motocycle.

11. Tare the scale by pressing the Φ/T button so that the scale reads 0.0 g.

Hold one ball beside the top of the meter stick with the ZERO end touching the table.

The purpose of this lab is to calibrate two force sensors properly. Observe the directional relationship between force pairs. Observe the time variation of force pairs. We need to explain Newton’s third law in simple language.

· I set up the apparatus as shown in the diagram. I then placed a

Copied the observations table in our notebook. Then recorded the mass of the beaker using the balance and wrote down the measured mass in the observation

Imagine a world without cancer, without the families suffering because a loved one is battling the fight against a disease that claims the most lives every year. This is what the American Cancer Society is aspires for in the long run. Ever since the American Cancer Society was created in 1913, they have been dedicated to eradicating the disease known as cancer. They put the best interest of the people and take action to make it happen. The American Cancer Society (ACS) uses its eventful history to take action to help the millions of people who are suffering from cancer and work to find advancements in the battle against it.

It is located in forward department of the R.M.M. It is equipped to deal with objects at 360 degrees and allows simple tasks like grasping, sorting, cutting, digging, examining, and moving objects. It can grasp mid size objects and has lifting capacity up to 90 kg if needed and deliver it into the testing platform of the PTP component on the rover. The robotic arm is designed with 12 servo motors to move and rotate the arm in any direction. The robotic mechanical arm uses a system of sensors to feel textures and sense temperatures to help with the testing and examining of samples. The arm uses a “push-pull' technique. The arm has a “tool revolver” to switch from tools as needed. The tool included in the barrel

10. How does varying the frequency effect contraction force? Which interval caused the greatest contraction?

Use a protractor to measure 30° from the equilibrium. Release the pendulum at this angle.

The pendulum was pulled to about 15 cm from the motion detector. In case of the mass on a spring, the mass was pulled till just a few inches away from the motion detector.

Epigenetics is a study that entails the heritage changes in gene expressions, which includes both the active and the inactive genes; the changes do not involve changes to the underlying DNA sequence. Meaning, it is a change in phenotypes without the differences in genotypes and consequently, affect how the cells read the genes. The epigenetic modification is a natural occurrence but apparently can be influenced by other several factors, including diseases, the environment, and age. Epigenetic changes can result in adverse damages and can end up causing infections such as cancer (Barton et al, 2016). This paper looks at what epigenetics entails, the hidden life of our genes, how food affects genes and how one can elongate life by improving health status.

An awakening transition took place in my life when I began the first steps toward my career. I quickly realized the importance of where the beginning would take me; It enhanced the vision of what I had already desired for my future.After graduating high school and taking the initiative to seek what my heart desired, I found that I was drawn to the business and healthcare industries. I decided to take my newfound discovery and become involved in business surrounding the healthcare industry with the intent to ensure quality care to patients in the business realm. Thus, directing myself on this right path of beginning my career I knew would be imperative for a successful future.

The touch detection features detection and each force can use or share some or all of the display area. For example, in one embodiment, a user can interact with an image displayed by touching and / or by applying a force in a proper position on the screen, with the corresponding position located anywhere on the screen. In another embodiment, the
