A proton moves at a speed or 1.9×103 m/s as it passes through and is perpendicular to a 0.45-T uniform magnetic field. Find the radius of the circular path.

According to newtons universal law of gravitation, which would change the parh of the ball so it traces out widest curved path possible?

Africtionless piston-cylinder contains 50 l of saturated liquid r-134a. the piston has a mass and an area resulting in an applied pressure of 500 kpa on the refrigerant. the refrigerant is now heated until its temperature rises to 70∘c. calculate the work (in kj) done during this process.

This is one type of line graph in which the independent variable is time plotted on the x axis and the dependent variable, also numerical, is plotted on the y axis.
