Answer:
a = 6.4 m/s²
Explanation:
a = F/m = 900 / 140 = 6.428571... m/s²
Answer:
15Ns
Explanation:
Given parameters:
Mass of the object = 10kg
Force impact = 5N
Time of action = 3s
Unknown:
Impulse applied on the object = ?
Solution:
Impulse is the force that acts on object within a period of time.
Mathematically;
Impulse = Force x time
Now insert the parameters and solve;
Impulse = 5 x 3 = 15Ns
Answer:
A Matter is not created or destroyed and the same amount of mass remains
Explanation:
In a chemical reaction, according to the law of conservation of matter, "matter is neither created nor destroyed and the same amount of mass remains in such a process".
- New kinds of products are formed in a chemical reaction because they undergo chemical changes.
- The chemical changes results in energy changes and formation of new kinds of substances.
- Based on the law of conservation of matter, mass is constant.
- Mass is not lost or gained.
