The amount of work done by the hairdryer is equal to 450 Kilojoules.
<u>Given the following data:</u>
To determine the amount of work done by the hairdryer:
Mathematically, the work done by an object with respect to power and time is given by the formula:
Substituting the given parameters into the formula, we have;
Work done = 450,000 Joules
<u>Note:</u> 1000 Joules = 1 Kilojoules.
Work done = 450 Kilojoules.

Answer:
The correct options here are C and D
Explanation:
DC here means "direct current". Direct current is characterized by it's flow of current been <u>unidirectional</u> (meaning it's current flows in just <u>one direction</u>). Thus, to get the answer to the question one must look for options that only move in a single direction. Options A and B move in a back and forth direction meaning they are not unidirectional.
A longitudinal wave moves in the same direction OR opposite direction to the direction of the propagating wave. This means longitudinal wave is also unidirectional. <u>Option C is correct</u>.
1st graders, in a line, going to the cafeteria also move in one direction (direction of the cafeteria). Thus, <u>option D is also correct.</u>

Answer:
the point the mass of an object will increase when traveling at relativistic speeds
Explanation:
m = m0/((1 - v2/c2))1/2
m0 = the mass measured at rest relative
<em>m = the mass measured by the observers on the other reference frame.</em>
<em>v = the speed of the object</em>
<em>c = the speed of light in a vacuum</em>
