Answer:
Sound is produced when an object vibrates, creating a pressure wave.As the particles vibrate, they move nearby particles, transmitting the sound further through the medium. The human ear detects sound waves when vibrating air particles vibrate small parts within the ear.
Answer:
15.7 m/s
Explanation:
The motion of the cannonball is a accelerated motion with constant acceleration g = 9.8 m/s^2 towards the ground (gravitational acceleration). Therefore, the velocity of the ball at time t is given by:
where
u = 0 is the initial velocity
g = 9.8 m/s^2 is the acceleration
t is the time
If we substitute t=1.6 s into the equation, we find the final velocity of the cannonball:
You are the source of the heat energy. You can minimize the heat energy by selecting the appropriate clothes to wear.
Simply put, our solar system is a speck compared to the Milky Way. Our Milky Way galaxy is a whopping 587 trillion light-years across.
