Answer:
The relative velocity of the motorcycle to a passenger in the car is 30 km/h
Explanation:
The question relates to the principle of relative velocity and reference frames
The given parameters are;
The velocity of the motorcycle, v₁ = 120 km/h
The velocity of the car, v₂ = 90 km/h
The relative velocity of an object X with regards to another object Y is the velocity the object X will seem to be moving with to an observer in the rest frame of object Y written as 
= 
- 
Therefore, the relative velocity of the motorcycle to the car is 
= v₁ - v₂, which give;
= 120 km/h - 90 km/h = 30 km/h
The relative velocity of the motorcycle to a passenger in the car = 30 km/h.
"• Diffusion - coffee and bacon particles are floating around
• They do not interact/blend with each other
• Because of fluidity, the particles are gliding past each other and filling the open space within the nose."
Answer:
Work is measured as the product of force and the displacement in the direction of the force. Work = force × displacement in the direction of the force.
1)the edges where two plates meet are plate boundaries.
2)a sudden slip on a fault triggers an earthquake as stress in the edge overcomes the tension that releases energy into waves that move through the surface of the earth and cause a shake.
3)motion of the ground, aftershocks, shuddering, trembling, wobbling, crashing, falling, breaking, and more
4) the outer layer of Earth is the crust (lithosphere) which is made up of hot molten rock and granite.
