what is the force of tension in a rope that spins a 250 g object in a vertical circle with a radius of .50 m if the mass at the top of the loop is traveling at 3 m/s?

Zeros that follow non-zeros numbers and are also to the right of a decimal point are significant

Afeather of mass 0.001 kg falls from a height of 2 m. under realistic conditions, it experiences air resistance. based on what you know about friction, what can you say about the kinetic energy of the feather as it reaches the ground? acceleration due to gravity is g = 9.8 m/s2. a. ke < 0.0196 j b. ke = 00196 j c. je = 0 j d. ke > 0.0196 j

In the circuit shown below, with each bulb holding a resistance of 60 ohms, how many amps of current are flowing? express your number as a decimal.
