Three balls leave the edge of a table at the same time. Ball A rolls off the table with an initial horizontal velocity. Ball B is launched at an angle and has both an initial horizontal and vertical velocity. Ball C is dropped from rest, and has no initial velocity.a) Explain which one(s) hit the ground first.

b) Explain which one(s) hit the ground last

Answers

Answer 1
Answer:

Explanation:

Balls A and C have the same initial vertical velocity of zero. Therefore, they land at the same time.

Ball B has a positive initial vertical velocity, so it hits the ground last.

What does the photoelectric effect prove?

Answers

The photoelectric effect is the process of producing electrons when light shines upon a certain material. The photoelectric effect proves that light is made up of particles or waves which means light has a wave-particle dual nature. Such nature is also present in electrons. 

Calculate the buoyancy of the balloon as "grams lift," that is, the difference between the mass of an equal volume of dry air at the same temperature and pressure and the mass of the He in the balloon. Assume the molar mass of air is 28.8 g/mol.

Answers

Explanation:

Since, the given balloon contains equal volume of dry air at the same temperature and pressure therefore, moles of air filled is equal to the moles of helium gas.  

Moles of air is 228363.69 moles and molar mass of air is 28.8 g/mol.

As we know that,  

     No. of moles of air = \frac{mass}{\text{molar mass}}

          228363.69 mol = (mass)/(28.8 g/mol)

                 mass = 6576874.341 g

Therefore, mass left is as follows.

                 6576874.341 g - 913454.77 g     (as 913454.77 g = mass of He)

                = 5664419.57 g                              

Thus, we can conclude that mass left is 5664419.57 g.

When the orientation of the Moon is just right, the high tides from the lunar bulge and the solar bulge line up, causing a very strong "Spring tide" --- an especially high high tide and a very low low tide. At what Moon phase(s) will you see a Spring tide?

Answers

Answer:

The correct answer is we see a Spring tide just after a full moon or no moon phase i.e. twice each lunar month.

Explanation:

A spring tide is popularly known as the "King Tide". As the name suggest, it has nothing to do with the season of spring. It gets its name from the idea of "springing forth". During a spring tide, the tidal range i.e. the difference between high and low water, is maximum. This happens when sun and the moon are on the same side of the earth (new moon) as well as when sun and moon are on the opposite side of the earth (full moon).
