Now you will use kinematics & the acceleration you calculated in the previous table to predict at which frame the cart should have reached the 2 m mark. Fill in the table below by determining how long (Δt) it would take to travel 2 m , how many frames are required for that much time (Δf), the frame at which your calculations predict it should reach 2 m (fpred), and the uncertainty of your prediction (pred). The formula for pred is below the table.

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me

according to jean piaget, in what stage of cognitive development are children able to understand conservation task?

b. preoperational

just took it

explanation:

to push or pull an object in a certain direction is known as force. a force in moving an object from one place to another.

force depends on the mass of an object. so, more is the mass of an object more will be the force required to move the object.

thus, we can conclude that the use of force to move an object is push or pull.
