Water atoms move more easily than ice
Ice is in a fixed crystal structure, it obviously has a lower temperature than liquid water, the state does not determine the charge, and when water freezes the crystalline structure actually makes it less dense than liquid because atoms are evenly spaced apart.
Answer:
30.81°
Explanation:
θ₁ = angle of incidence = 50°
θ₂ = Angle of refraction
n₂ = Refractive index of glass = 1.5
n₁ = Refractive index of air = 1.0003
From Snell's Law
Using Snell's law as:
Angle of refraction= sin⁻¹ 0.5122 = 30.81°.
Answer:
An unknown number of identical light bulbs are connected to a 15 V battery in parallel. The current through the battery is 2 A. If the light bulbs are connected to the battery in series, the current through the battery is 5 mA. How many bulbs are there?
3 bulbs are there from the analogy given above
Explanation:
Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects.
