A formula is
- a. the amount of each value needed.
- b. a solution for problems.
- c. an equation usually expressed in letters and numbers.

The correct option.
Answer to Problem 1RQ
The option ‘c’ is correct and the remaining options are incorrect.
Explanation of Solution
The basic definition of formula states that it is an expression expressed in terms of alphabets representing different physical quantities and numbers associated with them. The examples are as follows:
The following expression used to represent the kinetic energy.
Here,
m is the mass and
v is the velocity.
The following expression is used to represent the speed.
Here,
s is the distance and
t is the time.
Therefore, a formula is an equation, which is expressed in letters and numbers. So, the option ‘c’ is correct.
Conclusion:
Thus, the option ‘c’ is correct and the remaining options are incorrect.

Determine whether a current is induced in the metal loop. If so, indicate the direction of the current in the loop, either clockwise or counterclockwise when seen from the right of the loop. The axis of the magnet is lined up with the center of the loop. For the action depicted in (Figure 5), indicate the direction of the induced current in the loop (clockwise, counterclockwise or zero, when seen from the right of the loop). I know that the current is clockwise, I just dont understand why. Please fully explain why it's clockwise, Thank youarrow_forward
- A planar double pendulum consists of two point masses \[m_1 = 1.00~\mathrm{kg}, \qquad m_2 = 1.00~\mathrm{kg}\]connected by massless, rigid rods of lengths \[L_1 = 1.00~\mathrm{m}, \qquad L_2 = 1.20~\mathrm{m}.\]The upper rod is hinged to a fixed pivot; gravity acts vertically downward with\[g = 9.81~\mathrm{m\,s^{-2}}.\]Define the generalized coordinates \(\theta_1,\theta_2\) as the angles each rod makes with thedownward vertical (positive anticlockwise, measured in radians unless stated otherwise).At \(t=0\) the system is released from rest with \[\theta_1(0)=120^{\circ}, \qquad\theta_2(0)=-10^{\circ}, \qquad\dot{\theta}_1(0)=\dot{\theta}_2(0)=0 .\]Using the exact nonlinear equations of motion (no small-angle or planar-pendulumapproximations) and assuming the rods never stretch or slip, determine the angle\(\theta_2\) at the instant\[t = 10.0~\mathrm{s}.\]Give the result in degrees, in the interval \((-180^{\circ},180^{\circ}]\).arrow_forwardWhat are the expected readings of the ammeter and voltmeter for the circuit in the figure below?
