answer : Both cars will move backwards and stop due to friction.
Explanation:
Given that both cars are negatively charged, When the wedges are removed both cars will move backwards ( repelling each other ) because they are like poles, and Like poles repel each other. while unlike poles attract each other ( forward movement ) .
The cars will later come to a stop due to frictional forces between the cars and the surface.
Answer:
The object has 1250 Joules of Kinetic Energy.
Explanation:
Kinetic Energy =
mass*velocity²
KE =
mv²
KE =
(100kg)(5m/s)²
KE =
(100kg)(25m/s²)
KE = 1250
KE = 1250J
Answer:isotopes
Explanation:Isotopes form when the number of neutrons and atomic number change except for the protons don't change
Answer: Hydrogen atoms and oxygen atoms
Explanation:
The H stands for Hydrogen and there is two of those and the O is Oxygen and there is one of them giving you H2O
