Explanation:
a. Average speed = distance / time
= 100 m / 70 s
= 1.43 m/s
b. Average displacement = displacement / time
= 0 m / 70 s
= 0 m/s
Distance is the length of the path traveled. Displacement is the difference between the final position and initial position.
<span>1.8 × 10-6 C </span> You need to know that charge Q=C*V, that the capacitance C=epsilon_0*A/d and that the electric field between plates is given by E=V/d. Now use these three equations to solve for Q, divide by 2 and get answer
Answer:2,600 m/s
Explanation:13/ 0.005=2,600.
How does the angle of incoming light compare to the angle of light reflecting off of the surface?
- <em>The measurements of the angles are equal.</em>
