Using the equation for the final velocity in terms of masses and initial velocity of the gliders for a perfectly inelastic colli

tatuchka [14]

Answer:

Comparison has been made.

Explanation:

Consider perfectly inelastic collision.Two masses of m1 and m2 with initial velocities u1 and u2 before colliding, stick together after collision and move with common speed v. then according to the rule of momentum preservation

m1u1+m2u2= (m1+m2)v

$v= \frac{m1u1+m2u2}{m1+m2}$

If u1 and u2 are known the final common velocity can be determined

Initial kinetic energy is

$\frac{1}{2}m1u1^{2}+\frac{1}{2}m2u2^{2}$

The collion here is perfectly inelastic this means kinectic energy is not conserved. Therefore, initial kinectic energy is not equal to final kinectic.

$\frac{1}{2}m1v^{2}+\frac{1}{2}m2v^{2}$

When a 360 nF air capacitor is connected to a power supply, the energy stored in the capacitor is 1.85 x 10-5 J. While the capac

GaryK [48]

Answer:

(a) Approximately $10.1\; {\rm V}$ .

Explanation:

Let $C$ denote the capacitance of a capacitor. Let $V$ be the potential difference (voltage) between the two plates of this capacitor. The energy $E$ stored in this capacitor would be:

$\displaystyle E = \frac{1}{2}\, C\, (V^{2})$ .

Rearrange this equation to find an expression for the potential difference $V$ in terms of capacitance $C$ and energy $E$ :

$\begin{aligned}V^{2} &= \frac{2\, E}{C} \end{aligned}$ .

$\begin{aligned}V &= \sqrt{\frac{2\, E}{C}} \end{aligned}$

The capacitance $C$ of this capacitor is given in nanofarads. Convert that unit to standard unit (farads):

$\begin{aligned}C &= 360\; {\rm nF} \\ &= 360\; {\rm nF} \times \frac{1\; {\rm F}}{10^{9}\; {\rm nF}} \\ &= 3.60 \times 10^{-7}\; {\rm F}\end{aligned}$ .

Given that the energy stored in this capacitor is $E = 1.85 \times 10^{-5}\; {\rm J}$ , the potential difference across the capacitor plates would be:

$\begin{aligned}V &= \sqrt{\frac{2 \times 1.85 \times 10^{-5}\; {\rm J}}{3.60 \times 10^{-7}\; {\rm F}}} \\ &\approx 10.1\; {\rm V}\end{aligned}$ .

11. You want to calculate the displacement of an object thrown over a bridge. Using -10 m/s2 for acceleration due to gravity, wh

Natalka [10]

Displacement is d

Vf² = Vi² + 2 g d

(-20²) = (+10²) + 2 (-9.8) d

-19.6 d = 300

d = -15.3 m

negative means lower

time is t

d = Vi t + 1/2 g t²

-15.3 = 10 t + (-4.9) t²

4.9 t² - 10 t -15.3 = 0

t = 3.06 s
