Answer:
The natural frequency = 50 rad/s = 7.96 Hz
Damping ratio = 0.5
Explanation:
The natural frequency is calculated in this manner
w = √(k/m)
k = spring constant = 5 N/m
m = mass = 2 g = 0.002 kg
w = √(5/0.002) = 50 rad/s
w = 2πf
50 = 2πf
f = 50/(2π) = 7.96 Hz
Damping ratio = c/[2√(mk)] = 0.1/(2 × √(5 × 0.002)) = 0.5
Force = mass × acceleration = kg × m/s^2 = Newton
Sliding and Static.
Would be the right one here.
Answer:
Amount of energy required to change the 1kg of a substance without changing its temperature.
Yes, for temperature the unit should be in Kelvin, but that's easy (K = C + 273)
