The highest point of the wheel is the position of the wheel when its potential energy is greatest.
<h3>At what position of the wheel potential energy is greatest?</h3>
The position of the wheel when its potential energy is greatest when it is at the highest point because potential energy depends on the height of an object. If the object is at more height then it has more potential energy and vice versa.
So we can conclude that the highest point of the wheel is the position of the wheel when its potential energy is greatest.

Answer:
B
Explanation:
if you want to change an object's momentum you need to apply force to the object
Answer:
final volume = 640 ml
Explanation:
To answer this question, we will use Boyle's law which states that:
"At constant temperature, the product of the pressure and the volume of a given mass of gas will be constant"
Thereore:
P1V1 = P2V2
800*560 = 700*V2
V2 = 640 ml

Answer:
<em>C. planetary accretion</em>
Explanation:
<em>Astronomers think planets formed from interstellar dust gases that clumped together in a process called </em><u><em>planetary accretion</em></u><em>.</em>
Answer:
v' = -2.5 cm/s
Explanation:
given,
mass of toy car, m = 10 g
speed of right, u= 20 cm/s
mass of toy car, M = 24 g
speed opposite, u' = 35 cm/s
after collision
10 g car moves to left, v = 58 cm/s
v' = ?
using conservation of momentum
m u + M u' = m v + M v'
10 x 20 - 24 x 35 = - 10 x 58 + 24 x v'
24 x v' = -60
v' = -2.5 cm/s
speed of second car after collision = -2.5 cm/s
