Answer:
A vector ⇒ answer D
Step-by-step explanation:
* Lets revise some definition to solve the problem
- <em>Speed = distance ÷ time</em>
∵ Distance has no direction
∴ Speed has no direction
∴ Speed is a scalar quantity ⇒ (magnitude only)
- <em>Velocity = displacement ÷ time</em>
∵ Displacement has direction
∴ Velocity has direction
∴ Velocity has magnitude and direction
∵ Any vector has magnitude and direction
∴ Velocity is a vector quantity
∵ Velocity describes both speed (magnitude) and direction
∴ Velocity is a vector
Answer:
14.7
Step-by-step explanation:
So first you add all the marbles together, which equals 20.
-you the put 8 over 20= 8/20
Next you subtract one from the eight and add it all together again= 7/19
The equation should look like
-(7/19)·(8/20)
This would equal .147
simplified to 14.7
