OK.
You're sitting in a soft comfy chair, reading a book in your lap.
The book stays put, and you eventually start to get sleepy, because
there's almost no acceleration happening.
The chair you're sitting in is seat #27B in a huge jet taking you to visit
your grandparents who live a thousand miles away.
The airplane is maybe 7 miles up, passing over the ground at nearly
500 miles per hour, flying straight, level, and fast !
Blue light changes as it travels from diamond into crown glass at its speed increases.
Hi there!
Normal rain has a pH between 5.0 and 5.5, which is slightly acidic on the pH scale. Acid rain on the other hand has an average pH of 4.0, much more acidic than your average rain.
Therefore, the most likely pH of acid rain would be 4.0.
Answer:
<u>411.84 kg m/s</u>
Explanation:
Formula :
<u>Momentum = mass × velocity</u>
<u />
=========================================================
Given :
⇒ mass = 26.4 kg
⇒ velocity = 15.6 m/s
=========================================================
Solving :
⇒ Momentum = 26.4 × 15.6
⇒ Momentum = <u>411.84 kg m/s</u>
the answer is ( True ) .
the current is the same in series circuits .
