Answer:
Heya how have you been doing
Differentiate the components of position to get the corresponding components of velocity :
At <em>t</em> = 5.0 s, the particle has velocity
The speed at this time is the magnitude of the velocity :
The direction of motion at this time is the angle 
that the velocity vector makes with the positive <em>x</em>-axis, such that
wind = renew. wind needs to blow...very large "wind farms". no pollution
oil burns for heat or petrol. v high pollution. technology advanced
Answer: Money
Explanation:
Both money and energy are part of a cycle.
What does this mean?
Energy is not created nor destroyed, it is transformed into other forms of energy (for example: thermal energy, acoustic energy, kinetic energy, among others). Something similar happens with the flow of money in economic transactions, in which <u>money is exchanged for products, work or services and continues its flow in the market.</u>

Therefore, energy is a physical quantity with properties somewhat similar to <u>money</u>.
