Physics QUESTION #983

Question 3327

A small rigid spherical ball of mass $M$ is dropped in a long vertical tube containing glycerine. The velocity becomes constant after some time. If the density of glycerine is half the density of the ball, then the viscous force acting on the ball is:

2Mg
Mg
$\dfrac{3}{2}Mg$
$\dfrac{Mg}{2}$✔️

Correct Answer Logic:

At terminal velocity: Viscous force $= W - F_b$. Buoyancy $F_b = \rho_{glycerine} \cdot V \cdot g = \frac{1}{2}\rho_{ball} \cdot V \cdot g = \frac{Mg}{2}$. So Viscous force $= Mg - \frac{Mg}{2} = \frac{Mg}{2}$.

Mathematics QUESTION #4160

Question 3331

For the heat equation $u_t = k u_{xx}$ on a rod of length $L$ with insulated ends ($u_x(0,t) = u_x(L,t) = 0$), what are the eigenfunctions?

$\sin(\frac{n\pi x}{L})$
$\cos(\frac{n\pi x}{L})$✔️
$e^{\frac{n\pi x}{L}}$
$\sin(\frac{(2n+1)\pi x}{2L})$

Correct Answer Logic:

Insulated ends (Neumann BCs) $u_x = 0$ at $x = 0, L$ give eigenfunctions $\cos(\frac{n\pi x}{L})$ for $n = 0, 1, 2, ...$

Physics QUESTION #1171

Question 3333

The product of mass and velocity is known as:

Work
Moment
Impulse
Momentum✔️

Correct Answer Logic:

Momentum is defined as the product of mass and velocity: $\vec{p} = m\vec{v}$. It is a vector quantity measured in $\text{kg·m/s}$. Work is force times displacement, impulse is force times time (equal to change in momentum), and moment refers to torque.

Physics QUESTION #1055

Question 3338

A wire of resistance $R$ is cut into 8 equal pieces. Four pieces in parallel form one equivalent resistance, and two such sets in series. Net effective resistance:

$\dfrac{R}{16}$
$\dfrac{R}{8}$
$\dfrac{R}{64}$
$\dfrac{R}{32}$✔️

Correct Answer Logic:

Each piece has resistance $R/8$. Four in parallel: $R_p = \frac{R/8}{4} = \frac{R}{32}$. Two such sets in series: $R_{total} = 2\times\frac{R}{32} = \frac{R}{16}$. Wait: $\frac{R/8}{4}=\frac{R}{32}$, then $2\times\frac{R}{32}=\frac{R}{16}$. So answer is $R/16$ = option (1). Re-check: each piece $=R/8$, 4 in parallel $=\frac{R/8}{4}=\frac{R}{32}$, 2 in series $=\frac{2R}{32}=\frac{R}{16}$. Answer: option (1) = $R/16$.

Mechanical Engineering QUESTION #2437

Question 3340

The damping ratio (critical damping ratio) $\zeta$ for a viscously damped system is defined as:

$\zeta = c\omega_n / k$
$\zeta = c / c_{cr} = c / (2m\omega_n)$✔️
$\zeta = c / (2k)$
$\zeta = \sqrt{c / (2mk)}$

Correct Answer Logic:

The damping ratio $\zeta = c/c_{cr} = c/(2m\omega_n) = c/(2\sqrt{km})$. Systems with $\zeta<1$ are underdamped, $\zeta=1$ critically damped, and $\zeta>1$ overdamped.
