Higher frequency for lower wavelength...
.... If speed is fixed. ie no medium change.
Answer:
4.55 seconds
Explanation:
Speed=distance / Time
So Time = Distance /speed
=1550/340
Answer:
A=Gas
B= Solid
C=Liquid
Explanation:
A gas has the particles dispersed everywhere
so A is the gas
Liquid and Solid have them more close together
but the solid has them in some order
so as you can see
B is solid
and
C is liquid
Answer:15.66 J
Explanation:
mass of block
Force magnitude=7.5 N
Initial velocity =
Final velocity=
Initial Kinetic Energy=
=
Final Kinetic Energy=
=
Work Done =Final -Initial Kinetic energy=37.714-22.056=15.66 J
Answer:
The correct answer to the following question will be "12.0 N/C".
Explanation:
As we know,
Charged from the inside of the sphere throughout consideration of the electrical field or inside sphere.
⇒
Now,
⇒
On putting the values in the above formula, we get
⇒
⇒
Electric field within the sphere at that same distance of 20.0 cm from either the core.
⇒
On putting the values, we get
⇒
⇒
