Yes thank u teehee
.................... x
Distance = (30+40+50) = 120 km
It's back where it started, so displacement = zero
Okay so yeah u have to minus then subtract then decide it it’s a method i was taught to do
7.625 Newtons
work = force× distance
Newtons is an accepted value for force
so take the total 224 joules and decide by distance 32 meters to find force in Newtons
Answer:
Mechanical waves are waves that require a medium. This means that they have to have some sort of matter to travel through. These waves travel when molecules in the medium collide with each other passing on energy. One example of a mechanical wave is sound.
