A large punch bowl holds 3.90kg of lemonade (which is essentially water) at 24.0?C. A 5.80×10-2-kg ice cube at -10.0?C is placed in the lemonade.
(a) What is the final temperature of the system? Ignore any heat exchange with the bowl or the surroundings. (Celcius)
(b) What is the amount of ice (if any) remaining?
A starship has a mass of 8,500kg. It is moved by Yoda, 3.2m vertically upward and 14.8m horizontally toward Yoda, Determine the amount of force used to lift the ship
A woman rides a carnival Ferris wheel at radius 16.00 m, completing 4.10 turns about its horizontal axis every minute. What are (a) period of the motion, and the magnitude of her centripetal acceleration at (b) highest point and (c) the lowest poi..
The two blocks, m1 = 1.40 kg and m2 = 5, are connected by a mass less rope that passes over a pulley. The pulley is 12 cm in diameter and has a mass of 2.0 kg.
A stone with a mass of 0.700 is attached to one end of a string 0.8 long. The string will break if its tension exceeds 65.0 . The stone is whirled in a horizontal circle on a frictionless tabletop; the other end of the string remains fixed.
The woman then starts walking clockwise around the rim at .75 rad/s. in what direction and with what angular speed does the turntable rotate.
The electric field on the x-axis due to a point charge fixed at the origin is given by E=(b/x^2)i, Find the magnitude and sign of the point charge
A 0.144 kg baseball is moving towards home plate with a speed of 43.0 m/s when it is bunted. The bat exerts an average force of 6.50 Ã? 103 N on the ball for 1.30 ms, What is the final speed of the ball
A point particle that has a charge of 18.5 µC is located at x = 0, y = 0 and a point particle that has a charge q is located at x = 14.8 cm, y = 0. The electric force on a point particle that has a charge of 7.4 µC at x = 29.6 cm, y = 0 is -(19.7)..
