30 kg-m/s
The momentum of an object is given by the product of its mass and velocity. The momentum of bike 1 is 30 kg x 2 m/s = 60 kg.m/s to the right, and the momentum of bike 2 is 30 kg x 4 m/s = 120 kg.m/s to the left. When bike 1 and bike 2 collide in an isolated system, the total momentum is conserved. The magnitude of their total momentum is 60 kg.m/s + 120 kg.m/s = 180 kg.m/s.
No, passing showers and isolated showers are different. Passing showers refer to showers that are moving through an area and may not last long. Isolated showers, on the other hand, are showers that are scattered and not widespread in coverage.
Molecules have more kinetic energy when they are moving. This energy is proportional to their speed and mass, making them collide with each other and their surroundings.
Speed is a scalar quantity because it has magnitude (how fast an object is moving) but no direction associated with it. Velocity, on the other hand, is a vector quantity as it includes both magnitude (speed) and direction of motion.
A vector quality is defined as a quality that is described completely by both a direction and a magnitude. Velocity describes what direction something is moving as well as the speed it is moving, which makes it a vector quality.
20 kg-m/s
Magnitude of momentum before collision = (10 kg x 5 m/s) - (10 kg x 3 m/s) = 20 kg m/s. Magnitude of momentum after collision (assuming completely inelastic collision) = 20 kg m/s. Therefore, the magnitude of their combined momentum after collision will be 20 kg m/s.

You are not moving relative to the bicycle.
The "C" stands for "Collider" For something to collide there has to be a second something moving in a different direction to collide with. The contents of the two beams moving in opposite directions collide.
the magnitude is 43.3 and the direction is upward.
