A square raft has dimensions 2.161m x 2.161m x 30cm. When a 91.7kg chest is placed on the raft, the raft floats with its top surface 20cm above the water(10 cm is under water). The density of the water is 1033 kg/m^3
What is the mass of just the raft?
How strong it the buoyant force being exerted by the water on the raft?
How many crates can the raft hold (including the on on it)?

A square plate having dimensions of 8 cm x 8 cm x 2 mm is hung from one corner and lowered slowly to a water container where its hypotenuse is touching the surface. If Surface tension of water is 7.2 x 10^-2 Nm^-2 and density is 1000 Kgm^-3. Find the Apparent weight loss of the plate? Surface tension= 7.2 x 10^-2 Nm^-1 and the contact angle is zero.

Many people have imagined that if they were to float the top of a flexible snorkel tube out of the water, they would be able to breathe through it while walking underwater. However, they generally do not consider just how much water pressure opposes the expansion of the chest and the inflation of the lungs. Suppose you can barely breathe while lying on the floor with a 370 N weight on your chest. How far below the surface of the...

A U-tube contains liquid of unknown density. An oil of density
770 kg/m³ is poured into one arm of the tube until the oil column
is 13.5 cm high. The oil-air interface is then 4.5 cm above the
liquid level in the other arm of the U-tube. Find the density of
the liquid.

What pressure is incident on the bottom surface of the penny? A. just the pressure of the atmosphere B. about 150 N/m2 above atmospheric pressure C. 0 N/m2 D. about 300 N/m2 above atmospheric pressure The applied force to a hydraulic jack is 24 N to an area of 20...

The earth has a net negative charge of about -4.3 x 105 C. Since this charge is distributed more or less uniformly over the spherical earth, the force due to this charge is the same as if it were all placed at the Earth's center. A 6.0 kg satellite is orbiting with an orbital radius of 55000 km. If the satellite were also charged, then there would be an electric force in addition to the gravitational force a. What charge...

Partner: Date Name 11 Snell's Law Introduction When light passes from one material to another it is always bent away from its original path. This process is known as refraction and the change in direction depends on the change in optical density (or refractive index) of the two materials. A larger change in refractive index results in a larger change in angle between incoming and outgoing light beams. A light beam bends closer to the normal in the material with...
