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>
<u />
Therefore, energy is a physical quantity with properties somewhat similar to <u>money</u>.
Answer:
0.686 m/s
Explanation:
The principle of conservation says the sum of momenta before collision is equal to the sum of momenta after collision in an isolated system. Here, we assume the system is not acted upon by any external force.
The initial momentum = momentum of 1 st cart + momentum of 2nd cart
= 0.400 × 1.2 + 0.300 × 0 = 0.48 kg m/s
The final momentum = (0.400 + 0.300) × v (since they stick together)
0.700 v = 0.48
v = 0.686 m/s
Answer:
1) duration of the sessions
2) daily pattern days and ..
Answer:
1) 100 ...unb. and accelerate
2) 7...unb. and accelerate
Jenny is traveling southward. In order to stop, she needs a northward acceleration.
A better way to say it:
Jenny is traveling southward in her bumper car, so the direction of her velocity is south. In order to reduce her velocity to zero, a velocity of equal magnitude but directed north must be added to it. Then the change in velocity is positive northward, and the change in velocity per unit time is acceleration.
