What levers are in the human body? Biomechanics: Lever Systems in the Body The gastrocnemius muscle. The greater the ratio of the effort arm to the load arm, the more efficient the lever system is (i.e. the easier it is to move the load). The atlanto-occipital joint as a first class lever. The elbow joint […]
What are the advantages of AFM over SEM?
What are the advantages of AFM over SEM? SEM’s advantage is that it can measure the chemical composition of surface features, while an AFM can measure surface physical properties, such as magnetic fields (MFM), surface potential (SKPM), surface temperature (SThM), friction (SFM), and many other surface physical properties. How is AFM different from other microscopy? […]
Is there gravity underwater?
Is there gravity underwater? There is plenty of gravity underwater. That gravity is just offset by buoyancy, which is caused by the pressure in the column underneath a submerged object being greater than the pressure in the column above that object, resulting in net upward force on the object that mostly (but not completely) balances […]

What is the strength of the electric field at point 4 cm from the center?
What is the strength of the electric field at point 4 cm from the center? Explanation: A) At point 4 cm from the center, strength of the electric field is 0. Why does a dipole produce an electric field? Instead, on one surface the dipole heads create a positive surface charge, while at the opposite […]
What can we learn from radial velocity?
What can we learn from radial velocity? The radial velocity technique is able to detect planets around low-mass stars, such as M-type (red dwarf) stars. This is due to the fact that low mass stars are more affected by the gravitational tug of planets and because such stars generally rotate more slowly (leading to more […]
Which way is the South American plate moving?
Which way is the South American plate moving? Geological research suggests that the South American Plate is moving westward away from the Mid-Atlantic Ridge: “Parts of the plate boundaries consisting of alternations of relatively short transform fault and spreading ridge segments are represented by a boundary following the general trend.” As a result, the eastward […]
What do you think would happen over time if you put a plant BTB?
What states have no seat belt laws?
What states have no seat belt laws? New Hampshire is the only state that has no enforceable laws for the wearing of seat belts in a vehicle. What happened to automatic seat belts? Though more awkward for vehicle occupants, most manufacturers opted to use less expensive automatic belts rather than airbags during this time period. […]
