Answer:
it should be 8,000
Explanation:
because if you multiply the mass value by 1000, you will get 8,000

Answer:
You should have noticed that the number of atoms in the reactants is the same as the number of atoms in the product. The number of atoms is conserved during the reaction. However, you will also see that the number of molecules in the reactants and products are not the same.
KE=0.5 * mass* speed^2
Convert 72 km/h to m/s by dividing it by 3.6
72/3.6= 0.277778m/s
KE=0.5*1500*0.277778
= 208.3335J
= 208J
Answer:
The law of reflection (in physics) states that when a light ray is incident on a plane surface, the incident ray, the reflected ray and the “normal” to the surface of the mirror all lie in the same plane. It also states that the angle the incident ray makes with the normal is equal to the angle that the reflected ray makes with the normal.
