Q. A door of width 1.01 and height 2.03 weighs 279 and is supported by two hinges, one a distance 0.500 from the top and the other a distance 0.500 from the bottom. Each hinge supports half the total weight of the door.
Q. Two strings, one having linear density and length L1, the other having linear density 3 and length L2, are tied at a knot shown by the "X", and the ends are attached to walls as shown. The strings are held under the same tension. The total length of the strings is 4 m. A physics student plucks the knot, sending waves traveling towards the walls. What must lengths L1 and L2 be if the waves reach the walls at the same time.
A good model for a radio antenna is a dipole. P1 is on the perpendicular bisector of the dipole, and P2 is along the axis of the dipole in the direction of dipole vector ˆp. P1 and P2 are both a distance 100m from the center of the dipole.
The origin of the coordinate system and with a label at their heads. Two of these vectors are given in terms of the unit-vectors I and j as
At what angle have to the laser beam in the diagram be aimed at mirrored ceiling in order to hit the midpoint of the far wall? The length of the room is a=4.9 m and its height is b=3.00 m.
A horizontal force of 213 N is exerted on a 1.90 kg discus as it rotates uniformly in a horizontal circle (at arm's length) of radius 1.60 m. determine the time for one revolution of the discus. Round the answer to 2 decimal places.
A 1.20 liter flask contains a certain quantity of ideal gas at 305 K. next an equal number of molecules of the same gas are added to the flask, after which the absolute pressure is 1.30 times its original value. What is the final temperature.
In a game of basketball, a forward makes a bounce pass to the center. The ball is thrown with an initial speed of 2.50 m/s at an angle of 15.5° above the horizontal. It is released 0.73 m above the floor. What horizontal distance does the ball cover ..
What is the magnitude of an average acceleration of the ball
A 2.10kg snowball is fired from a cliff 8.55 m high with an initial velocity of 11.90 m/s, directed 47.0° above the horizontal. (a) Using energy techniques, find speed of the snowball as it reaches the ground below the cliff. What is that speed (b) i..
A 1600 kg submarine rises straight up towards the surface. Seawater exerts both an upward buoyant force of 16430 N on the sub, with a downward resistive force of 1000 N. What is the submarine's acceleration.
A man of mass 65 kg falls stiff-legged straight down from a height of 2m. He lands on one foot. The femur is a bone in the leg with the length L=.65m, and a cross-sectional area of about 2.0 x 10^-4m^2. The Young's modulus for bone is 9.4x 10^9 N/..
