<span>When a tuning fork vibrates over an open pipe and the air in the pipe starts to vibrate, the vibrations in the tube are caused by d. resonance. When the tuning fork vibrates near the open end of the cylinder, the sound waves from the fork are sent into the pipe. When one object vibrates, it forces another object to vibrate at the same frequency and this is called resonance</span>
Answer:
When acid rain falls on the marble stone, it dissolve calcium when the acid present in the rain water react with the calcium of the marble stone.
Explanation:
Acid rain is formed when gases such as carbondioxode and sulfur dioxide etc that is emitted from vehicles and industries goes to the atmosphere and react with the water present in the form of clouds and formed the water acidic. When this water comes down to the earth, it damage many materials due to acid present in it.
Answer:
84m
Explanation:
Using the kinematics equation we can come up with the answer:
Where:
Vf = final velocity
Vi = initial velocity
t = time
In your problem we have the following given:
Vf= 0 m/s
Vi = 21 m/s
t = 8 seconds
The Vf is zero because the car stopped. The distance given in this case is not useful in determining the car's distance so we will solve it. So just fill in the equation with the given:
Thankfully, the deer was not hit!
The answer is A because all the other ones contribute
