If a ball has 100 J of potential energy on the shelf, how much energy does it have if it falls one-fourth of the way down to the ground?
(When answering, can you just type in the answer instead of putting a photo, because I haven’t been able to open any of the photos) Thanks!

If vx = 7.00 units and vy = -7.60 units, determine the magnitude of v⃗ . determine the direction of v⃗ .

Object a has a length of 3 cm, a width of 2 cm, and a height of 4 cm. object b is dropped into a graduated cylinder. it displaces 19 ml of water. the volume of object a is: a: greater than the volume of object b b: less than the volume of object b c: equal to the volume of object b

Ionic compounds can be readily dissolved in water because the high dielectric constant of water screens and decreases the force between the oppositely charged ions.
