Answer:
2.5 ms^-2
Explanation:
acceleration
= (final velocity - initial velocity)/time
= [(40m/s) - (20m/s)]/8s
= (20m/s)/8s
= 5/2 m/s²
= 2.5 m/s²
= 2.5 ms^-2
Answer:
Create
Broken
Explanation:
Bond formation or creation requires the use of energy. Energy is used during bond formation between chemical species. The energy is required for the reaction to occur.
- When bonds are broken, energy is released
- Bond breaking process is a procedure that releases energy.
- This energy makes them able to react.
I think wind is anther answer
Answer:
......................
Explanation:
It is called so because it is applicable on all bodies having mass, and the bodies will be governed by the same law, that is newton's law of gravitation. Thus, as it is applicable universally, it is called as universal law.
Answer:
B and D
Explanation
Gravitational potential energy does not relate to graphs and it is about a moving object so b and d would not be correct
