This question doesn't make much sense. If both objects have the same momentum, they will 'bounce off' of one another, if one has more momentum than the other, then both of the objects will go in the direction that that object was travelling but with less momentum and therefore less speed. If a block was travelling that > way with a momentum of 5kgm/s and another is travelling that < way with a momentum of 20kgm/s then both blocks would travel that < way with a momentum of 15kgm/s because you do the larger momentum - the smaller momentum. If a block was travelling that > way with a momentum of 10kgm/s and another was travelling that < way with a momentum of 10kgm/s, they would collide and the one going that > way would go < that way with a momentum of 10kgm/s and vice versa as they would pass their momentum to each other so they'd keep the same momentum.

Answer from: Quest

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm. the wire diameter is d = 0.9 mm. the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2) in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.

Answer from: Quest

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
