Answer:
The car moved a distance .
Explanation:
First we need to know: <em>How much time will the tomato spend in the air?</em>
From Kinematics:
where and is gravity's acceleration.
When the tomato touches the car again,
Then, we have:
⇒
Also from Kinematics we have:
Which is very simple because we can take initial position 0 and there's no acceleration in the x direction. And
So, taking
I believe it would be 127.8 pounds. weight = mass x gravity
Answer:
is it 2 please am I right or not
The answer to this question is 2400Hz
Answer:
1) Because of the size and time the sound wave moves, an echo is typically transparent and easy to discern. Since reverberations typically don't have enough distance or time to fly, they will pile up on top of each other, making it impossible to understand.
People will detect an echo if the distance between the source of the sound and the reflected body is greater than 50 feet. When a sound wave is bounced off a nearby surface, it may create a reverberation.
2) The speed of sound in hot air is more than that in cold air because air molecules are traveling faster in hot air.
