The answer is B. Remain still.
True because friction happens when two things are rubbed against each other and it creates force and sliding something vigorously against something else can create force.
Average speed is the ratio of total distance moved by Chi in total time interval
So here we will have
Total distance = 100 m + 400 m
Total time taken = 5 min + 15 min = 20 min
now by the formula of average speed we know that
so average speed will be 1.5 km/h
Hi there! When a chemical Reaction happens, the tell tale signs are as listed:
~The chemical produces bubbles
~ The Chemical emits an odor
~ The liquid forms a solid(Precipitate)
~ There is a change of color
~ And last but not least a change in temperature!
Hope this can help! Good luck!
Yes. If a downward force is created, it will be felt at the end of the rope as well.
