the tallest man made structure At present is theWarszawa radio massin Warsaw Poland.This radio mast rises 646m above ground near

ly 200M higher than the Sears tower in Chicago. Suppose a worker at the top accidently Knocks A hammer off the tower if the force acting on the hammer is 3.6N And its Acceleration is 9.8m/s calculate the mass of the hammer. most show work please

All of that fluff at the beginning is interesting, but completely irrelevant
to the question.  The question is just asking for the mass of an object
that weighs 3.6N on Earth.

                           Weight = (mass) x (acceleration of gravity)

                              3.6N = (mass) x (9.8 m/s²)

Divide each side
by  9.8 m/s :           Mass = 3.6N / 9.8 m/s² = <em>0.367 kilogram</em> (rounded)

A student calculates the density of a copper cube to be 4.15 g/cm . If the accepted value is 8.64 g/cm the percentage error in h
Helen [10]

 The percentage error in his experimental value is -51.97%.

<h3>What is percentage error?</h3>

This is the ratio of the error to the actual measurement, expressed in percentage.

To calculate the percentage error of the student, we use the formula below.

Formula:

  • Error(%) = (calculated value-accepted value)100/(accepted............. Equation 1

From the question,

Given:

  • Calculated value = 4.15 g/cm
  • accepted value = 8.64 g/cm

Substitute these values into equation 1

  • Error(%) = (4.15-8.64)100/8.64
  • Error(%) = -4.49(100)/8.64
  • Error(%) = -449/8.64
  • Error(%) = -51.97 %

 

Hence, The percentage error in his experimental value is -51.97%.

Weekend A<br> Assignment<br> Differentiate between forced and damped oscillation
4vir4ik [10]

Answer:

A damped oscillation means an oscillation that fades away with time while Forced oscillations occur when an oscillating system is driven by a periodic force that is external to the oscillating system.

Explanation:

Damping is the reduction in amplitude (energy loss from the system) due to overcomings of external forces like friction or air resistance and other resistive forces. ... When a body oscillates by being influenced by an external periodic force, it is called forced oscillation.
