What is the rock’s velocity when it reaches the bottom? How do you know?

Answers

Answer 1
Thus the rock hits the surface after about 5.38 s. Thus the rock hits the surface with a velocity of about -10.01 m/s. If you want to know the velocity of the object at some point before it hits the ground, use the distance the object has fallen at that point in place of the distance to the ground in either equation.

The temperature of the areas surrounding Kochi before each storm was about 10°C and there was the same amount of water vapor in the air.

Given this information, which storm do you predict will have the most rainfall and why?

Answers

Is it about room temperature
Storm number 1 because number 2 and 4 will be snow or ice and it wouldn’t be number 3 since 1 has wind and wind helps rain because it pushes the clouds together and the clouds hit each other and release water through them as rain.

Go around your house and hit (or tap) ten different objects. The objects should be different shapes and made of different material (choose things to hit that won’t break!). Each object is a different medium for sound. Try to hit each using the same amount of energy.

Describe each object that you hit and the sound it made.
Rank the ten objects from loudest to softest.

Make some conclusions based on your results from Steps 1 and 2. For example, are there a certain shapes or materials that are better or worse media for sound travel?

Stairs, wall, door, window, picture, floor, desk, backpack, paper, bed all of these produce different sound.

What is sound?

Sound is defined as an acoustic wave is a vibration that travels through a gas, liquid, or solid transmission medium. In terms of human physiology and psychology, sound is the brain's receipt of these waves and perception of them. A mechanical disturbance that causes an equilibrium condition to be disturbed and propagates through an elastic material medium.

The vibration of items creates sound, which travels from one place to another through a medium. Vibration is the phrase used to describe an object's to-and-fro or back-and-forth motion. Vibrations are generated by objects in motion.

Thus, stairs, wall, door, window, picture, floor, desk, backpack, paper, bed all of these produce different sound.

Imaging playing a game of baseball on the moon, which has less gravity than Earth and no atmosphere. How would you want to change the game to make it play fairly and fun again?

Answers

Deflate the ball so it’s not as bouncy

A technique to change the game to make it play fairly and fun again is to deflate the ball in an attempt make it less bouncy.

Discussion:

A characteristic of the baseball game is that the baseball is less bouncy in comparison to other sports like football and basketball.

When the baseball game is played on the moon with a less gravity; the ball tends to ascend more as the force of gravity is lower compared to that of the earth.

Ultimately, lowering the air pressure in the baseball makes the ball less bouncy and the game may become fun to play again.
