A wooden log of density 2g/cm3 and volume 50 cm3 fall on the surface of water. Calculate its buoyant force.

Physics
1 answer:
Sveta_85 [38]3 years ago
5 0

Answer:

The buoyant force =98 N (OPTION A)

Explanation:

Buoyant force refers to whether an object can float in water or air caused by the upward force exerted on a submerged object, which is equal to the weight of the fluid displaced.

Buoyant force is given by:

Fbuoyant = PA

Where, P = pressure

          A = area

While, in a situation where there is volume, area and height involved we have:

Fbuoyant = pgha = gpv

Where, p = density of the fluid

        g = gravity

         h = height of immersed part

         a = area

         v = volume of immersed part of the body of the fluid

given data:

density = 2g/cm3

volume = 50 cm3

Fbuoyant = gpv

  = (9.8m/s²) x (2 x 10∧-^{3} x 10∧^{6} Kg/m³)  x (50 x 10∧-^{4} m²) = 98 N

Where, gravity = 9.8m/s²

A 10 kg rock that has been dropped from a 60 meter high cliff experiences an average force of air resistance of 30 N. Calculate
lesya692 [45]

Answer:

4086 J

Explanation:

The potential energy is transformed to kinetic energy less the frictional energy. Potential energy= mgh where m represent mass, g is acceleration due to gravity and h is the height of cliff

Since we have force of air resistance, work done due to air resistance will be product of force and distance

mgh-Fh= 0.5mv^{2}= KE

Substituting 10 Kg for m, 9.81 for g and 60 m for F then the kinetic energy at the bottom will be

KE= 10*9.81*60- (30*60)=4086 J

astraxan [27]

Answer:

It is possible to statically charge objects by rubbing it against carpet fibers, but I'm not sure if that was in the article that you read.

Explanation:

Static charge can build up via carpet fibers.

The place theory of hearing is better than frequency theory at explaining pitch perception for __________ sounds
atroni [7]
The answer is : Low frequency sounds

place theory is a theory of hearing which states that our perception of sound depends on where each component frequency produces vibrations along basilar membrane, which is very sensitive to low frequency sound
