28Ni62 may be described as the most strongly bound nucleus because it has the highest B. E. per nucleon. Its neutral atomic mass is 61.928349 a. m.u..

Find its mass defect, its total binding energy and binding energy per

nucleon.

Given, mass of neutron=1.008665amu

mass of proton=1.007825amu

1amu=931.5MeV.

An astronomer at the equator measures the doppler shift of sunlight at sunset. from this, she calculates that earth’s tangential velocity at the equator is 465 m/s. the centripetal acceleration at the equator is 3.41  10 2 m/s 2 . use this data to calculate earth’s radius.

Gather reliable information to brent make his decision. to gather this information, use newspapers, call insurance companies or look at their web sites, and review consumer magazines and web sites. also, look at the manufacturer web site or for information about gas mileage. list the sources you use and take notes.

If two students are running down the hall toward each other, trying to get to class, and they have the same mass and acceleration, what will happen when they collide? will their forces cancel out or will each one experience a reaction?
