If I had an object of 5kg, which travels at a constant speed of 5 m/s is moving around a circle of perimeter 5m for 1 second. Obviously its speed would equal to 5 m/s however because its displacement...

I push a box in space from a spaceship toward an area free from space dust. the initial push provides a initial velocity of 5.00m/s Thrusters on the box provide a constant force of 10N. How...

A cord attached to a 3.63-kg mass is wrapped around a wheel of radius 0.610 m and released. The moment of inertia of the wheel is 2.71 kg · m2. If the wheel rotates on frictionless bearings, the acceleration...

This is a momentum/impulse problem

Does it take a strong magnetic field to affect plant growth? Would it need to be a coil around the plant or would just having an electromagnet next to the plant increase it's growth?
