which coordinates identify a location of a city that has the latitude of 38.0°N and a longitude of 25.0°W

A bucket of water of mass 16.0kg is suspended by a rope wrapped around a windlass, that is a solid cylinder with diameter 0.350m with mass 11.4kg. The cylinder pivots on a frictionless axle through its center.

Consider the third period of the periodic table. Which element has the smallest atomic radius? A) argon B) scandium C) silicon D) sodium

A rock is thrown horizontally off a cliff with an initial speed of 3 m/s. The initial position of the rock is 10 meters above the ground. How long is the rock in the air?

A particle of mass 2.0 kg is moving in the xy plane at a constant speed of 0.80 m s in the x direction along the line y 4 m As the particle travels from x 3 m to x 3 m the magnitude of its angular momentum with respect to the origin is?

A plane is flying east at 135 m/s. The wind accelerates it at 2.18 m/s^2 directly northeast. After 18.0s, what is the magnitude of the displacement of the plane?

The same constant force, F, is applied to two blocks. The first block has a mass of M and the second block has a mass of 2M. Both blocks are initially at rest and the force acts on each of them for the same period of time, t.

Does the air in our atmosphere have mass?

Your instructor hands you a closed flask partly filled with room-temperature water. When you hold it, the heat transfer between your bare hands and the flask causes the water to boil. Quite impressive! How is this accomplished?
