Answer:
a) V1=11.05m/s V2=92.07m/s V3=17.24m/s
b) KE = 16238.26J
Explanation:
For tangential speeds:
For the kinetic energy, it can be calculated as:
Where:
So,
KE=16238.26J
1. the change in position of an object from start to finish, a vector quantity . . . . .<em> displacement</em>
2. a portion of space that contains a value for a measurable quantity at every point in space . . . . .<em> field </em>
3. speed = (distance) / <em>(time to cover the distance)</em>
4. the length of the entire path an object travels from start to finish . . . . . <em>distance</em>
5. a measurement that has both magnitude and direction . . . . . <em>vector</em>
6. a change in displacement with respect to time . . . . .<em> velocity</em>
7. a mental or physical construct or description that describes a physical phenomenon . . . . . <em>model</em>
8. a change in velocity with respect to time . . . . . <em>acceleration</em>
9. a measurement that only expresses magnitude, such as time, temperature, distance, and speed . . . . . <em>scalar</em>
10. objects that are thrown or launched in the air and are subject to gravity . . . . . <em>projectile</em>
Answer:
Colour
Malleability
Ductility
Lustre
Conductivity
Softness
Explanation:
Color : Silver-White.
Malleability : Capable of being shaped or bent.
Ductility : Easily pulled or stretched into a thin wire.
Luster : Has a shine or glow.
Conductivity : Good transmission of heat or electricity.
Softness : Soft enough to be cut with a knife.
The wave nature of light, due to the experiment having bright and dark bands corresponding to places where you have constructive and destructive interference.
