Forces and Motion:Question 2 Student 1 rides in a moving car and observes a bus traveling east. She estimates
that it is traveling at a rate of 20 kilometers per hour (km/h). Student 2 is standing
on the sidewalk and observes the same bus at the same time. She estimates that
it is moving east at a rate of 50 km/h.

Which best explains this difference?

Kinetic energy = 1/2mv^2. since the mass is constant we can form a ratio of it's kinetic energy at 60 divided by that at 30 to see ke(60)/ke(30) = +(60^2)/30^2). this may be said to 300% increase.

This did i unseated, sorry

The geological theory that states that pieces of earth's lithosphere are in constant slow motion is the theory of plate tectonics.

Answer: 1.4 seconds which is the third optionexplanation: current is defined as the flow of charge per timetherefore, the equation that relates current, charge and time can be expressed as follows: i = δq / δtwhere: i is the current given = 1.8 ampereδq is the charge given = 2.5 coulombδt is the time required for the flow of the given charges to give the 1.8 ampere.substitute with the givens in the above equation to get the time as follows: 1.8 = 2.5 / δtδt = 2.5 / 1.8 = 1.38888 which is approximately 1.4 secondshope this was !
