A container has a large cylindrical lower part with a long thin cylindrical neck. The lower part of the container holds 12.5 m^3 of water and the surface area of the bottom of the container is 5.00 m^(2 ). The height of the lower part of the container is 2.50m and the neck contains a […]
ultraviolet light causes sunburns, while visibly even greater intensity does not. Why is this so?
A robot probe drops a camera off the the rim of a 389 m high cliff on Mars, where the free fall acceleration is 3.7 m/s^2. Find velocity with which it hits the ground and the time required for it to reach the ground.
household 120 v outlets are made to accept three ponged plugs . one of the prongs attaches to the live wire 120 v, and another attaches to neutral wire that is connected to the ground.what is the third round prong for
Assignment:1.)A wheel free to rotate about its axis that is not frictionless is initially at rest. A constant external torque of +50 N·m is applied to the wheel for 21 s, giving the wheel an angular velocity of +650 rev/min. The external torque is then removed, and the wheel comes to rest 120 s later. […]
Consider three identical metal spheres, A, B, and C. Sphere A carries a charge of +4q. Sphere B carries a charge of +7q. Sphere C carries no net charge. Spheres A and B are touched together and then separated. Sphere C is then touched to sphere A and separated from it. Lastly, sphere C is […]
