the kinetic energy is the same as the canoes weight times its speed times the force of gravity.
Answer: C. Light can cause electrons to be released from the surface of a metal
Explanation:
A compound is a substance made up of 2 or more elements
Magnetic fields that attract and repel, gravity, and friction with the ground/track are the forces that act upon a meglev train. a maglev train is a train that is propelled by magnets on both the train and the tracks. gravity plus friction plus magnetic fields equals a maglev train.
Answer:
d.3.0
Explanation:
Step 1: Calculate the final volume of the solution
The final volume is equal to the sum of the volumes of the initial HCl solution and the volume of distilled water.
V₂ = 100 mL + 100 mL = 200 mL
Step 2: Calculate the final concentration of HCl
We will use the dilution rule.
C₁ × V₁ = C₂ × V₂
C₂ = C₁ × V₁/V₂ = 0.002 M × 100 mL/200 mL = 0.001 M
Step 3: Calculate the pH of the final HCl solution
Since HCl is a strong acid, [H⁺] = HCl. We will use the definition of pH.
pH = -log [H⁺] = -log 0.001 = 3
