Answer:
We experience interference while listening to the radio. A radio station works by sending and receiving radio waves. Since the radio waves are being interfered with other waves which must have a wave nature.
The interference is the net result of two individual waves. It can be constructive or destructive interference and is the property of waves and not particles.
This interference is an example of electromagnetic radiation. Thus we experience wave behavior of electromagnetic radiation in our daily communications.
Answer:
2 ohms
Explanation:
Hi there!
Ohm's law states that
where V is the voltage, I is the current and R is the resistance.
Plug in the given information (I=7.5, V=15) and solve for R

Divide both sides by 7.5 to isolate R

Therefore, the circuit resistance would be 2 ohms.
I hope this helps!
Answer:
You are finding acceleration, so it would be 15 m/s2
Explanation:
30 divided by 2
Same formula as the last question. x = vt + (1/2)at^2. In this case, v = 0, t = 12, and a = 2.0. Plug in the values and solve for x (which is change in position)
x = (0)(12) + (1/2)(2.0)(12^2)
x = (1/2)(2.0)(144)
x = (1)(144)
x = 144
So the car will travel 144 meters in 12 seconds.
Answer:
0 Newton
Explanation:
If the velocity becomes constant the acceleration will be zero and the net force will be zero because:
force = mass x acceleration
Since acceleration is 0:
force = mass x 0
force = 0
