Inertia IS always present. Inertia is NOT the force that causes objects to continue moving in circles, that is centripetal force. Centripetal force is NOT always present. Centripetal force DOES pull objects toward the center of a circle. <span> Inertia and centripetal force DOES cause circular motion. Thank you and eat sand fren ;)</span>
The given situation below describes a standing wave because the string is fixed at both ends. A standing wave having three anti-nodes will have a wavelength that is two-thirds the length of the string. After getting the wavelength, this can be multiplied with the frequency to get the wave speed.
For this problem:
wave length = (2/3)(length of string: 68 cm)
wave length = (10/3 cm)
wave speed = wave length x frequency
wave speed = (10/3 cm) x (180 Hz)
wave speed = 600 cm/s or 0.6 m/s
Answer:
The two equations below express conservation of energy and conservation of mass for water flowing from a circular hole of radius 3 centimeters at the bottom of a cylindrical tank of radius 10 centimeters. In these equations, delta m is the mass that leaves the tank in time delta t, v is the velocity of the water flowing through the hole, and h is the height of the water in the tank at time t. g is the acceleration of gravity, which you should approximate as 1000 cm/s2.

Answer:
A.
Mass per page = mass of book / number of pages
Mass per page = 2.5kg / 500 pages = 0.005kg
B.
Mass per page = mass of book / number of pages
Total mass = 2.5kg = 2,500grams = 2,500,000mili grams
Mass per page = 2500000mg / 500 pages = 5000mg
Answer:
a)
b)Does not affect the long term.
Explanation:
Given that
A = A0 cos(ωt)
This is linear equation so integration factor ,I
Now by using linear equation property
b)
at t= 0
So the initial condition does not affect the long term.
