Until he was in his seventies, Henri LaMothe excited audiences by belly-flopping from a height of 13 m into 35 cm. of water. Assuming that he stops just as he reaches the bottom of the water and estimating his mass to be 72 kg, find the magnitudes of the impulse on him from the water.
The magnetic field in acertain region is 0.128 ,and its direction is that of the z-axis in the figure.
What is the magnetic flux across the surface abcd in the figure?
What is the magnetic flux across the surface befc ?
Part C What is the magnetic flux across the surface aefd?
What is the net flux through all five surfaces that enclose the shaded volume?
(a) How far from a 50.0-mm-focal-length lens must an object be placed if its image is to be magnified 2.00 X and be real?
(b) What if the image is to be virtual and magnified 2.00 X?
Starting with an initial speed of 5.00 m/s at a height of 0.300 m, a 1.50 kg ball swings downward and strikes a 4.60kg ballthat is at rest, as the drawing shows. a. using the principle of conservation of mechanicalenergy,find the speed of the 1.50 kg ball just before impact b. assuming that the collision is elastic, find the velocities( magnitude and direction ) of both balls just after thecollision c. how high does each abll swing after the collision, ignoringair resistance?
