A spinning top is the answer
The correct answer is C. Velocity is a vector and requires a direction.
Explanation:
In physics both speed and velocity are used to study the motion of a body; however, they are slightly different. In the case of speed, this describes the rate of change in position based on distance and time, because of this, speed is based on a magnitude or quantity. On the other hand, velocity is a vector because it does not only includes a change of position but the direction of motion usually based on a specific location reference.
Considering this, it can be concluded the difference between speed and velocity is that "velocity is a vector and requires a direction" because velocity includes both the distance and time (speed) along with the direction while speed focuses only on time and distance.
Answer:
It is displaced.
Explanation:
As the coaster travels. The kinetic and potential energy shifts up and down. But when it shifts, some of the energy is displaced and lost.
Wooden desk it doesn’t conduct or absorb heat as much as metal or plastic
To develop this problem it is necessary to use the expression that allows us to convert the degrees Celsius to Fahrenheit. The expression that allows to realize it is given mathematically by:
In this way for 33.2 °C:
In this way for 38.2°C
Expressed in a range term, we can say that the measure in degrees Fahrenheit is:
![[91.76\° F , 100.76\° F]](https://tex.z-dn.net/?f=%5B91.76%5C%C2%B0%20F%20%2C%20100.76%5C%C2%B0%20F%5D)
