Answer:
A. whenever there is an opportunity for energy dispersal, the energy always spreads out
Explanation:
Answer:
A. Constructive
B. Destructive
C. Destructive
D. Constructive
Explanation:
Constructive interference takes place at locations along the path of two superposed waves where the waves are in phase such that a high or low point of one of the waves corresponds with a high or low point of the other wave which gives a resulting wave amplitude which is the sum of the amplitudes of the individual waves
Destructive interference takes place at locations along the path of two superposed waves where one wave is out of phase with the other wave such that a high or low point of one of the waves coincides with a low or high point of the other wave respectively thereby cancelling the effect of the other wave and giving a resulting wave that has an amplitude which is the difference in the amplitudes of the individual waves
Therefore;
At point A, the peak of each wave partially coincides resulting in constructive interference
At point B, the peak of the blue wave and the trough of the red wave partially coincides resulting in destructive interference
At point C, the through of the blue wave and the peak of the back wave partially coincides resulting in destructive interference
At point D, the trough of each wave partially coincides resulting in constructive interference.
Answer:
x = 8.3 cm
y = 5.4 cm
Explanation:
x position
200(0) + 100(12) + 350(12) / (200 + 100 + 350) = 8.307692...
y position
200(0) + 100(0) + 350(10) / (200 + 100 + 350) = 5.3846153...
Answer with Explanation:
We are given that
Number of turns =n=11.2 /cm=
1 m=100 cm
I=24.2 mA=
Radius of solenoid,r=9.74 cm=
Current in straight conductor,I'=17.1 A
a.Magnetic field in solenoid=
Magnetic field in straight wire=
Where 
b.Magnitude of magnetic field=
Hence,the magnitude of magnetic field =
Answer:
<h2>392 J</h2>
Explanation:
The potential energy of a body can be found by using the formula
PE = mgh
where
m is the mass
h is the height
g is the acceleration due to gravity which is 9.8 m/s²
From the question we have
PE = 20 × 9.8 × 2
We have the final answer as
<h3>392 J</h3>
