Q: A lorry is traveling in a straight line and it is accelerating. The total forward force on the lorry is F and the total backward force is B.
Which is larger, force F or force B? Explain your answer.
A: Force F, because there must be an unbalanced force in order for the lorry to move and accelerate (in this case, moving forward, so force F is bigger).
The characteristic in which all electromagnetic waves share....
- SAME speed (not just speed!)
- They're all electromagnetic waves.
addition: Speed can affect both thinking and braking distance.
Well done. I can see that you've thought carefully about how to improve.
