The correct solution for the resultant of the wolf spider is:
R² = 75² + 50²
<h3>Resultant formula</h3>R² = (Displacement 1)² + (Displacement 2)²
Where

<h3>Data obatined from the question</h3>The following data were obtained from the question.
The solution for the resultant displacement of the wolf spider can be obtained as follow:
R² = (Displacement 1)² + (Displacement 2)²
R² = 75² + 50²
Thus, the correct answer to the question is:
R² = 75² + 50²

Answer:
The value is
Explanation:
From the question we are told that
The mass of the lithium nucleus is
The radius is
The speed of the lithium nucleus is
Given that the lithium nucleus is travelling in a circular path, the magnetic force will be equivalent to a centripetal force so
And
So
=>
=>
Answer:
Explanation:
Power Dissipated in a resistor is given by two methods i.e.
and
where
both formula gives Power but Former is used when voltage is constant i.e. when resistors are in parallel and the later is used when the resistor are in series .
Though can also be used in series but we have to calculate the Potential drop across each resistor then we can apply the formula.
Similar is with
First we have to calculate current through each resistor then we can apply the Formula
