To convert the expanded form into exponent form or what is commonly known as scientific notation, you have to move the decimal place until you reach the last digit. From its original place, there are 6 places in order to reach to the last digit. Since you moved to the right, the exponent would have a positive sign. The scientific notation would be 6×10⁶ m.

Answer:
It is a technique of collection and storage of rain water
Answer: first option, the work output of the hairdryer will be less than the work input.
Explanation:
1) The work output measured in watts is the power of hair dryer measured in joules per second.
2) The hair dryer converts electrical energy from the wall outlet to mechanical and thermal energy: hot wind.
3) Nevertheless, you can never expect a 100% efficiency of the machines: due to friction, some energy is converted into useless energy.
So, efiiviency = power output / power input< 1 ⇒
power output = work output / time
input power = work input / time
⇒ work output / work input < 1
⇒ work output < work input.
Which is the first option: the work output of the hairdryer will be less than the work input
