The greatest ocean depths on the Earth are found in the Marianas Trench near the Philippines. Calculate the pressure due to the ocean at the bottom of this trench, given its depth is 11.0 km and assuming the density of seawater is constant all the way down.
A space traveler weighs 130 pounds on earth. What would the traveler weigh on another planet whose radius is three times that of earth and whose mass is twice that of earth.
A 0.20-kg billiard ball travelling at a speed of 15.00 m/s strikes the side rail of a pool table at an angle of 60 degrees. If the side rail rebounds at the equal speed and angle what is the change in its momentum?
In a control system, an accelerometer consists of a 4.99-g object sliding on a calibrated horizontal rail, Find the force constant of the spring required for the calibration to be correct
For the circuit shown below, C = 0.113 µF and = 103 V. The switch throw is rotated to contact b after having been at contact for the long time, and 3.47s later the potential difference across the capacitor is equal to 1/2. What is the value of R.
The force of gravity acting on the arm acts through point A. Identify the magnitudes of the tension force t in the deltoid muscle and the force s of the shoulder on the humerus (upper-arm bone) to hold the arm in the position shown.
