shows a cubical box that has been constructed from uniform metal plate of negligible thickness. The box is open at the top and has edge length L = 66 cm. Find (a) the x coordinate, (b) the y coordinate, and (c) the z coordinate of the center of mass of the box.
Illustrate what is the maximum load that can be hung from a copper wire of diameter of 0.47 mm before it breaks?
Design a circuit to control the temperature of a water bath at a set-point temperature of 85°C. Choose a resistive sensor and draw up a circuit that will provide control around the set-point.
Two loudspeaker, 4.0 m apart and facing each other, play identical sounds of the same frequency. You stand halfway between them, where there is a max. of sound intensity. moving from this point toward one of the speakers, you encounter a min. of s..
Suppose that the displacement of an object is related to time according to the expression x = Bt2. What are the dimensions of B?
The cubit is an ancient unit. Its length equals six palms. (A palm varies from 2.50 to 3.50 inches depending on the individual.) We are told Noah's ark was 300 cubits long, 50 cubits wide and 30 cubits high.
assume the current in the coaxial cable, see the figure , is not uniformly distributed, but instead the current density varies linearly with distance from the center: for the inner conductor and for the outer conductor. Each conductor still carrie..
A space vehicle is travelling at 5800 km/h relative to the Earth when the exhausted rocket motor is disengaged and sent backward with a speed of 74km/h relative to the command module. The mass of the motor is four times the mass of the module. What i..
If a woman lifts a 20.0 kg bucket from a well and does 6.00 kJ of work, how deep is the well? Suppose that the speed of the bucket remains constant as it is lifted.
Find the work done by this force on the particle and the final speed of the particle as it moves along a path.
A 99 kg man lying on a surface of negligible friction shoves a 71 g stone away from himself, giving it a speed of 4.0 m/s. What speed does the man need as a result.
The spring is compressed against the floor a distance 2.5 cm and released. If the spring constant is 119 N/m, illustrate what is the magnitude of the spring force acting on the toy at the moment it is released?
