A clock is designed that uses a mass on the end of a spring as a timing mechanism. If the oscillation time needed is exactly one
user100 [1]

Answer:

The value is  k  =  51.34 \  N/ m

Explanation:

From the question we are told that

   The  mass is  m =  1.3 \  kg

   The needed oscillation time is  T = 1 \ s  

 Generally the spring constant is mathematically represented  as

         k  =  \frac{4 \pi^2 * m }{ T^2}

=>      k  =  \frac{4* 3.142^2 * 1.3 }{ 1^2}

=>      k  =  51.34 \  N/ m

In the process of loading a ship, a shipping container gets dropped into the water and sinks to the bottom of the harbor. Salvag
jolli1 [7]

Answer:

57.885.8 kg   weight of the container

Explanation:

The volume of the balloon * density of water = buoyant force of balloon

 volume of a sphere = 4/3 pi r^3

                                   = 4/3 pi * (1.5)^3 = 14.14 m^3   <===balloon volume

Now,   find the buoyant force on the container ALONE ....

             5.8 * 2.6 * 2.8  * 1027  = 43 364  kg   <=====  buoyant force

Now add the buoyant force of the balloon to find the weight

             43 364  +   14.14 * 1027 = 57885.8   kg
