Darren filled ocean water, fresh water, bottled water, and tap water into four different containers. He then dropped identical g

olf balls into each of the four containers. The picture below shows the golf balls in the four different liquids.
Into which of these containers did Darren most likely fill ocean water?

Container 1,2,3 or 4?

I would say container 1

Answer:

Container 2

Explanation:

Out of all the water containers, ball in 2nd container is floating because it has ocean water.

Ocean water has a huge amount of salt in it and a saline water has greater density than fresh water, bottled water or tap water. So if you will drop a golf ball inside the container of ocean water, it will eventually float as density of golf ball is less that density of ocean water.

Same theory helps to explain why bodies do not sink in ocean, rather float on its surface.

If I were to fill a water bottle full of air and go up in elevation, would the water bottle expand or shrink? If I were to fill
alina1380 [7]

Answer:

a. It would shrink

b. It would expand

Explanation:

a. Since the water bottle is filled with air at atmospheric pressure at 20000 ft, and since atmospheric pressure decreases with altitude, when we go up in elevation.

The pressure exerted by the molecules of air in the water bottle seek to balance out the atmospheric pressure as we go higher. Since the atmospheric pressure exerted by the molecules of air in the atmosphere are greater than that exerted by the molecules of air in the water bottle, this causes the volume of the water bottle to decrease and thus shrinks the water bottle until the pressure balances out

b. Since the water bottle is filled with air at atmospheric pressure at 20000 ft, and since atmospheric pressure increases with decreasing altitude, when we go down in elevation.

The pressure exerted by the molecules of air in the water bottle seek to balance out the atmospheric pressure as we go lower. The water bottle expands until the atmospheric pressure outside equals the pressure inside the water bottle.this causes the volume of the water bottle to increase and thus expands the water bottle until the pressure balances out

A cardinal (Richmondena cardinalis) of mass 4.20×10−2 kg and a baseball of mass 0.146 kg have the same kinetic energy. What is t
bekas [8.4K]

Explanation:

It is given that,

Mass of cardinal,m_c=4.2\times 10^{-2}\ kg

Mass of baseball, m_b=0.146\ kg

Both cardinal and baseball have same kinetic energy. We need to find the ratio of the cardinal's magnitude p_c of momentum to the magnitude p_c of the baseball's momentum.

E_c=E_b

Kinetic energy is given by, E=\dfrac{p^2}{2m}

\dfrac{p_c^2}{2m_c}=\dfrac{p_b^2}{2m_b}

(\dfrac{p_c}{p_b})^2=\dfrac{m_c}{m_b}

\dfrac{p_c}{p_b}=\sqrt{\dfrac{m_c}{m_b}}

\dfrac{p_c}{p_b}=\sqrt{\dfrac{4.2\times 10^{-2}}{0.146}}

So, \dfrac{p_c}{p_b}=\dfrac{53}{100}

So, the ratio of cardinal's magnitude of momentum to the magnitude of the baseball's momentum is 53 : 100

1. A person is lifting a suitcase into the trunk of a car. Assuming the suitcase is already in the air, draw the FBD and write t
Alik [6]

Answer:

Explanation:Assume you are lifting an object with mass 20 kg from the ground to a height of 1.5 m.  Assume that you are exerting a constant force in the upward direction and that you are moving the object upward with uniform velocity.  The net force on the object is zero.  The force you are exerting is equal in magnitude and opposite in direction to the force of gravity.  As you are lifting the object you are doing work on the object.
