Answer:
current doubles
Explanation:
V = IR
so as v doubles I doubles
Answer:
Radio Waves
Explanation:
Radio wave is a type of electromagnetic radiation notorious for their use in technologies used for communication like air traffic control, mobile phones, televisions and remote-controlled toys. Radio waves have the longest wavelength in the electromagnetic spectrum and are easily transmitted through air.
A radar gun uses radio waves to tell how far away an object is. To do that, the radar tool emits a focused radio wave and listens for any echo. If there is an item, say a car within the route of the radio wave, it's going to replicate some of the electromagnetic energy, and the radio wave will return to the radar gun. Radio waves flow via the air at a steady pace, so the radar gun can calculate how far the object is based totally on how long it takes the radio signal to return.
Answer:
Volume of gasoline overflow(v)= 40/9 L (I.e. 4.44 L)
Explanation:
Use <u>v1</u><u>/</u><u>T1</u><u>=</u><u>v2</u><u>/</u><u>T2</u>
.....overflow(V)=v2-v1
<u>Note</u><u>;</u> <em>Take</em><em> </em><em>temperature</em><em> </em><em>in</em><em> </em><em>absolute</em><em> </em><em>scale</em><em> </em><em>or</em><em> </em><em>kelvin</em><em> </em><em>scale</em><em> </em>
Speed of sound = 340 m/s
Time taken for sound to reach observer = 3.2 seconds
Height = speed x time
= 340 x 3.2
= 1,088 meters
