Answer:
I only know answer A and it's 2825.28 N/m, with rounding it's 2825.5
Explanation:
Use the m*g*h=1/2*k*x^2 equation
96*9.81*60=1/2*k*2^2
5650.56=2k
5650.56/2=2825.28N/m
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°.
A contact force is a type of force which act on an object by coming in contact with the object. Examples of contact force that acts through a force field are: applied force, frictional force, air resistance force, tension, spring force, etc.
Examples of forces that act through a force field are gravitational force, electromagnetic force, the weak interaction and the strong interaction.
