Answer: IT IS STRONGLY REPELLED
Explanation: The laws of guiding magnetic attraction or repulsion of Magnetic materials,states that when like poles are brought together they repel each other, but when unlike poles are brought together they are attracted.
The rod will be strongly repelled because the forces on the rod is greater and has the same Polarity as the charged ball.
Given
F = 55 N to ring the bell
P = 250 W
t = 0.85 s
Procedure
First let's calculate the force for 250W of power.
With 250W it is not possible to reach the bell to ring it.
Now let's calculate the value for 500W
Force is doubled when power is doubled
The answer OC. It can be changed only if all scientists approve the change
The correct answer is The electromagnetic waves appear more in red color.
<span>Since red is at the low-frequency end of the visible spectrum, we say that light from a receding star is shifted toward red, or redshifted.</span>
Answer:
"2Ω" is the net resistance in the circuit.
Explanation:
The given resistors are:
R1 = 3Ω
R2 = 6Ω
The net resistance will be:
⇒ 
On substituting the values, we get
⇒ 
On taking L.C.M, we get
⇒ 
⇒ 
⇒ 
On applying cross-multiplication, we get
⇒
