To Choose: The correct option.
Answer to Problem 27R
Option D
Explanation of Solution
Introduction:
Metals are good conductors of electricity. To
In metals there are number of free electrons present which move in random directions. When the electric potential is applied to the metals, the electrons flow in one direction and conduct the electricity. In general, metals are good conductors of electricity and heat. So, the electrical conductivity is the property of metals when electrons are moving freely in metals.
Conclusion:
Thus, option D is correct.

Express your answer in meters to three significant figures. Learning Goal: To practice Problem-Solving Strategy 4.1 for projectile motion problems. A rock thrown with speed 12.0 m/s and launch angle 30.0 ∘ (above the horizontal) travels a horizontal distance of d = 19.0 m before hitting the ground. From what height was the rock thrown? Use the value g = 9.800 m/s2 for the free-fall acceleration. PROBLEM-SOLVING STRATEGY 4.1 Projectile motion problems MODEL: Is it reasonable to ignore air resistance? If so, use the projectile motion model. VISUALIZE: Establish a coordinate system with the x-axis horizontal and the y-axis vertical. Define symbols and identify what the problem is trying to find. For a launch at angle θ, the initial velocity components are vix=v0cosθ and viy=v0sinθ. SOLVE: The acceleration is known: ax=0 and ay=−g. Thus, the problem becomes one of…arrow_forward
