Two explanations might include two sets of colorless solutions that might yield a gas. What comes to mind is the production of carbon dioxide which could come from a soluble carbonate, such as sodium carbonate solution, and an acid, such as vinegar or hydrochloric acid. A second possibility is a gas such as ammonia. This could be produced by the reaction of a soluble ammonium compound, such as ammonium chloride, and a base such as sodium hydroxide.
Explanation:
Power output of the bulb:
0.021 × 60 W = 1.26 W
Energy produced by the bulb in 1 second:
E = Pt
E = (1.26 W) (1 s)
E = 1.26 J
Round as needed.
Answer:
Object A
Explanation:
given,
Object A
mass,m₁ = 1.4 Kg
speed of the car,v₁ = 14.2 m/s
object B
mass,m₂ = 2 Kg
speed,v₂ = 5 m/s
Kinetic energy of the object will be absorbed by you when it hit you.
KE₁ = 141.148 J
kinetic energy of the object B
KE₂ = 25 J
Hence, the Object A will feel worse if hit you because of the kinetic energy of the object A is more.
