A stone with a mass of 0.600kg is attached to one end of a string 0.800m long. The string will break if its tension exceeds 65.0N. The stone is whirled in a horizontal circle on a frictionless tabletop; the other end of the string remains fixed. Find the maximum speed the stone can attain without breaking the string.
A 1.0-cm-diameter pipe widens to 2.0 cm, then narrows to 0.5 cm. Liquid flows through the first segment at a speed of 9.0 m/s.
A diving board length = 5.40 that weighs 230 is supported by two pillars. One pillar is at the left end of diving board; the other is distance = 1.60 away. Determine the magnitude of the force exerted by the left pillar while a 90.0 diver stands a..
Suppose a single electron orbits about a nucleus containing two protons (+2e), as would be the case for a helium atom from which one of the naturally occuring electrons is removed. The radius of the orbit is 4.41 × 10-11 m. Determine the magnitude..
A gymnast of mass 69.0 kg hangs from a vertical rope attached to the ceiling. You can ignore the weight of the rope and assume that the rope does not stretch. Use the value 9.81 for the acceleration of gravity.
A woman on a 10 speed bicycle travels at 9 m/s relative to ground as a she passes a little boy on a tricycle going in the opposite direction. If the boy is travelling at 1m/s relative to the ground, how fast does the boy appear to be moving relati..
A ball has fallen to the street below, and a passerby returns it by launching it at an angle of 53.0° above the horizontal at a point 26.0 m from the base of the building wall. The ball takes 2.20 s to reach a point vertically above the wall.
What is angular velocity of the cockroach-disk system
A car moves along the x-axis in the positive direction. Find the sign (+,-) of the velocity and acceleration of the car for each situation: 1. The car moves AWAY from the origin and gets FASTER 2.
A particular guitar string is supposed to vibrate at 203 Hz, other than it is measured to actually vibrate at 208 Hz. By what percentage must the tension in the string be changed to get the frequency to the correct value.
A 1g plastic pellet is accelerated by an electirc field of 1000V/m over a gap of 12 cm, What is the velocity of the pellet after crossing the gap
What hormones are hypersecreted causing hyperglycemia and hypertension? What is the cause and what physical factor allow to rule out thyroid problem.
suppose the radius of the ball is very small compared to other length scales in the problem. Take starting level as step 0, the next step down as step 1, and so on.
