A particle undergoes two displacements, measured from the positive x-axis, with counter- clockwise positive. The first has a magnitude of 11 m and makes an angle of 65 degrees with the positive x-axis. The resultant displacement has a magnitude of 10.1m directed at an angle of 122 degrees from the positive x-axis. find the magnitude of the second displacement in meters.
A diver 32.0 m deep in 8.00 °C fresh water exhales a 1 cm diameter bubble. What is the bubble's diameter just as it reaches the surface of the lake, where water temperature is 25°C? Hint: suppose the air bubble is always in thermal equilibrium wit..
What is the magnitude of the horizontal net force. An 845-N sled is pulled a distance of 168 m. The task requires 1.20 multiplied by 104 J of work and is done by pulling on a rope with the force of 121 N. At what angle is the rope held.
