Answer 2

Answer:

1)Spaceships are provided with heat shields to protect them during exist and reentry of the earth's atmosphere.

2)

• The main issue with smooth paper is that the paper is also friction less and even the pen is designed to write smoothly.
• So, as you know without friction writing is just impossible.
• If you try to write it will be often slipping down

3)Frequency is the property which decides whether a given sound is audible or inaudible.
