The left ventricle of the heart accelerates blood from rest to a velocity of + 25.9 cm/s.
(a) If the displacement of the blood during the acceleration is + 2.01 cm, determine its acceleration (in cm/s2).
(b) How much time does blood take to reach its final velocity?
A 95 kg man standing on a surface of negligible friction shoves a 75 g stone lying at his feet, giving it a velocity of 4.0 m/s. What velocity does the man obtain accordingly.
A single-turn circular loop of radius 8.00 cm is to produce a field at its center that will just cancel the earth's field of magnitude 0.7G directed at 70 below the horizontal north direction. Find out the current in the loop.
How much current is contained within the width of a thin ring concentric with the wire if the ring has the radial width of 12.0 µm and is at a radial distance of 1.2 mm.
I put a packing peanut on top of it, and it only took one rotation--or crank--to knock the material off from the machine and onto the ground. mass of the peanut=.001 kg, distance from the machine to the peanut=.0005m.
