1 point Tiffany's mass is 60 Kg. She climbs the 1.75-m vertical ladder of a slide,
slips and reaches a velocity of only 4.25 m/s at the bottom of the slide. How
much energy was "lost" as Tiffany slid? What actually happened to the "lost"
energy? W=4= K. Ef – K. Ei

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min

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.
