A beach ball with a volume of 5,000 cm3 is pushed underwater. What is the magnitude of the buoyant force pushing upwards? The de

Kobotan [32]

<h2>Hello!</h2>

The answer is:

The buoyant force is equal to 49N.

The buoyant force is the force that pushes upwards and object when it's submerged in water, this force is always trying to move the object to the surface of the liquid or water. We must consider that the volume of water or liquid displaced is equal to the volume of the submerged object.

We can calculate the buoyant force using the following formula:

$F_{B}=Density*VolumeDisplaced*GravityAcceleration$

Where,

Density is the density of the water or liquid.

Volume displaced is equal to the volume of the submerged object.

Gravity acceleration is the acceleration due to gravity.

So, from the statement we know that:

$VolumeDisplaced=BeachBallVolume=5000cm^{3}\\\\Density=1\frac{gram}{cm^{3} }=\frac{0.001kg}{cm^{3} }\\\\g=9.8\frac{m}{s^{2} }$

Now, substituting and calculating we have:

$F_{B}=Density*VolumeDisplaced*GravityAcceleration$

$F_{B}=0.001\frac{kg}{cm^{3}*} *5000cm^{3}*9.8\frac{m}{s^{2} }$

$F_{B}=49\frac{Kg.m}{s^{2}}=49N$

Hence, we have that the correct answer is:

The buoyant force is equal to 49N.

Have a nice day!

SashulF [63]

Answer:

1. Desert

2. United States

3. Explorer

Explanation:

Given the nature of the Sahara desert, it is believed to cover about 9.4 million kilometer square. Thereby is about the same size as the United States including the region of Alaska and Hawaii.

Because of its level of hotness, it is considered very challenging to explorers.

Therefore, it can be concluded that The Sahara. The largest desert DESERT on the planet. A searing wilderness the size of the UNITED STATES The toughest challenge an EXPLORER can face.
