A cube 10.0 cm on each side has a density of 2.053 x 10^4 kg/m^3. It’s apparent weight in fresh water is 192 N. Find the buoyant
insens350 [35]

Answer:

9 N

Explanation: Given that L = side of the cube = 10cm = 0.1m

Mass = Density * Volume

Let’s determine the volume of the cube in m^3.

V = L^3

V = 0.1^3 = 0.001m^3

Mass = 0.001 * 2.053 * 10^4 = 20.53kg

Weight = 20.53 * 9.8 = 201.194

Buoyant force = 201.194 – 192 = 9.194 N

This is approximately 9 N.

Assume the acceleration of the object is a(t) = −32 feet per second per second. (Neglect air resistance.) With what initial velo
alukav5142 [94]

Answer:

v_i=189.315ft/s

Explanation:

We are going to use the accelerated motion formula v_f^2=v_i^2+2ad on the vertical component taking the upwards direction as positive.

Since <em>at maximum height the speed will be v_f=0m/s</em>, the formula can be written as v_i=\sqrt{-2ad}, which for our values is:

v_i=\sqrt{-2(-32ft/s^2)(560ft)}=189.314553059ft/s=189.315ft/s

Written to three decimal places.
