C. Electromagnetic waves do not always need a medium to travel.

Electromagnetic waves<span> differ from mechanical </span>waves<span> because they </span>do not require a medium<span> to travel. This means that </span>electromagnetic waves can travel not<span> only through air and solid materials, but also through the vacuum of space. </span>Also, they are transverse so they do not need a medium material. For an electromagnetic wave to be admitted, there must be an <span>acceleration of an electric charge.

I hope this helps:)</span>

olasank [31]

Answer:

The unit of measurement called standard atmosphere (atm) is defined as 101,325 Pa. Common multiple units of the pascal are the hectopascal (1 hPa = 100 Pa), which is equal to one millibar, and the kilopascal (1 kPa = 1000 Pa), which is equal to one centibar.

300N effort is applied to lift the load of 900N by using a first class lever. If the distance between the load and fulcrum is 20
Klio2033 [76]

Answer:

Effort=300N

Load=900N

Load distance=20m

Now,

Ed=(L*Ld)/E

Ed=(900*20)/300

Ed=1800/300

Ed=6m

camcorder has a power rating of 14 watts. If the output voltage from its battery is 3 volts, what current does it use?
Aliun [14]
Power rating tells you the amount of electricity a particular device like a camcorder needs. The power, voltage and current are all related using the equation: P = IV.

Therefore, 

P = IV
I = P/V = 14 watts/3 volts = 4.67 A

Thus, the current must be 4.67 Amperes for the camcorder.
