Answer:
On the way back up the hill, the car converts kinetic energy to potential energy. In the absence of friction, the car should end up at the same height as it started. ... The total energy of the ball stays the same but is continuously exchanged between kinetic and potential forms.

Explanation:
Atoms bond in other to achieve a stable valence electron shell. Through bonding, atoms with incomplete valency in the outer shell may accept, lose or share electrons with another atom in other to achieve a stable outer shell or configuration.
Ionic bonding:
Ionic or electrovalent bonding simply occurs when atoms accept or lose electrons in their outer shell in other to achieve stability. Elements that require 1 atom to achieve stability accepts from elements which requires losing 1 atom in other to achieve a stable outer shell.
Example is Sodium chloride (NaCl) sodium loses one atom, which chlorine accepts and both achieve a stable outer shell.
Covalent bonding simply refers to electron sharing between atoms. Instead of losing or accepting, the atoms bond by sharing electron to achieve stability. Such is the bonding between Hydrogen and Oxygen in the formation of H2O, oxygen requires two electrons to attain stability, each hydrogen atom requires one each to attain stability, through sharing oxygen attains two more electrons, one each from the hygrogen atoms and the oxygen atom also shares one electron with each hydrogen atom. Then all the atoms atoms stability.
Answer:
The ring has a larger moment of inertia.
Explanation:
Given that the mass of disc=61 kg
Let the radius of the disc is R
The moment of inertia of the disc having mass m, about the axis passing through the center of the disc,
Mass of hoop = 36 kg
As the radius of disc and hoop is the same, so the radius of the hoop is R.
The moment of inertia of the ring (hoop) having mass m, about the axis passing through the center of the disc,
Hence, the ring has a larger moment of inertia.
as we know that
acceleration = 0.50 m/s^2
distance traveled = 125 m
time taken = 20 s
now we will use the equation of kinematics
so its initial speed must be 1.25 m/s
Electromagnetic force. It is where alike forces ( negative, negative & positive , positive) repel and opposite forces ( negative & positive ) attract.
