A 200g particle oscillating in SHM travels 66cm between the two extreme points in its motion with an average speed of 110cm/s. F
IgorC [24]
For a:v = d / Δt 
110 = 0.66 / Δt 
Δt = 0.66 / 110 
Δt = 0.006 s 
the period is: 
T = 2Δt 
T = 2*0.006 
T = 0.012 s 
the frequency is the inverse of the period. so: f = 1 / T 
f = 83.3333333 Hz (about; Hz = 1/s) 
b. T = 2π√(m/k) 
being the mass m = 200g = 0.2 kg = 2*10^-1 kg, π = 3.14 (about) and T = 0.012, k is equal to: 
0.012 = 6.28√(2*10^-1 / k) 
0.012 / 6.28 = √(2*10^-1 / k) 
0.00191082803 = √(2*10^-1 / k) 
2*10^-1/ k = 0.000003
2*10^-1 / k = 3*10^-6 
k = 2*10^-1 / 3*10^-6
k = 6.67*10^-5

now using hooke's law:
F = -kx 
F = - 6.67*10^-5* 3.3*10^-1
F = -2.20x10^-5m
F = -0.22 *10^4 N

___________is the tendency of an object to resist change in its state of motion
Mademuasel [1]
Inertia
<span> An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.this tendency to retain its motion is referred to as Inertia </span>

A typical laboratory centrifuge rotates at 3700 rpm . Test tubes have to be placed into a centrifuge very carefully because of t
Alexus [3.1K]

Answer:

Explanation:

acceleration of test tube

= ω² R

= (2πn)² R

= 4π²n²R

n = no of rotation per second

= 3700 / 60

= 61.67

R = .10 m

acceleration

= 4π²n²R

= 4 x 3.14² x 61.67² x .10

= 14999 N Approx
