The table shows information about four objects resting at the top of a hill. A 3-column table with 4 rows titled Four Objects at Rest on a Hill. The first column labeled Object has entries W, X, Y, Z. The second column labeled Mass (kilograms) has entries 50, 35, 62, 24. The third column labeled Potential Energy (Joules) has entries 980, 1029, 1519, 1176.
Which object is on the tallest hill?

W
X
Y
Z

It is Z i believe.

Explanation:

Potential Energy = mass x gravity x height

W: 980 = (50)(9.8)(h)

X: 1029 = (35)(9.8)(h)

Y: 1519 = (62)(9.8)(h)

Z: 1176 = (24)(9.8)(h)

simplify:

W: 980 = 490h

X: 1029 = 343h

Y: 1519 = 607.6h

Z: 1176 = 235.2h

Divide from both sides of each equation:

W: (980/490) = h

X: (1029/343) = h

Y: (1519/607.6) = h

Z: (1176/235.2) = h

Simplify the left side:

W: 2 = h

X: 3 = h

Y: 2.5 = h

Z: 5=h

the five characteristics of adolescence are biological growth and development, and undefined status, increased decision making, increased pressure and the search of self.

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7
