If measuring experimental results, what can you predict about the work output of a 1200 watt hair dryer? the work output of the
eimsori [14]

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

If a block has the mass of 15.00 grams and measurements of 5.00cm by 3.00cm by 2.00cm what is the volume of the block?
Natalija [7]

Answer:

Volume = 30cm³

Explanation:

A block is a geometrical figure and its volume, -look at the figure-, follows the equation:

Volume = Width*Length*Height

As the measurements of the block are 5.00cm, 3.00cm and 2.00cm, the volume is:

Volume = 5.00cm*2.00cm*3.00cm

<h3>Volume = 30cm³</h3>
