Before you jump to conclusions, there is a kind of "time" without motion. I don't mean that motion is impossible, but rather that motion is possible, but it just doesn't happen. So let's say the universe doesn't move, even though it has the potential to, because something is stopping the motion (whatever it is). Could…
Hi everyone! What percentage of light penetrates the calm/smooth water surface when the light source is IN the water and shines out of the water? Is this comparable to a light protection film that only lets through about 60% of the light? Thank you:)
So, I hope you understand what I mean. We often had problems like this in class, like determining the lowest speed of a swing at the highest point of its circular path. And we always used the following approach: centripetal force equals weight. But how can they be the same? So why does the body…
You have to calculate the distance traveled by a car in 4.5 hours at a speed of 70 km/h. The formula for speed is v=delta x/ delta t Is it true that v=70 km/h and delta t=4.5 h? So you have to calculate delta x? However, that comes out to 0.0643km and that doesn't make…

I also see that.or the text is somewhat twisted. I can hardly imagine that a task is so confusing.
If the car is accelerated, it is not a uniform movement.
I think there’s something missing.
