Una pila consta de dos polos, uno negativo y uno positivo. No basta con conectar un extremo del conductor al polo negativo del que salen los electrones. Hay que conectar el otro extremo al polo positivo, al que vuelven los electrones

What is the mirror formula for curved mirrors

Reika [66]

The mirror formula for curved mirrors is:
$\frac{1}{f}= \frac{1}{d_o}+ \frac{1}{d_i}$
where
f is the focal length of the mirror
$d_o$ is the distance of the object from the mirror
$d_i$ is the distance of the image from the mirror

The sign convention that should be used in order to find the correct values is the following:
- $f$ : positive if the mirror is concave, negative if the mirror is convex
- $d_i$ : positive if the image is real (located on the same side of the object), negative if it is virtual (located on the opposite side of the mirror)

A 23 g bullet traveling at 230 m/s penetrates a 2.0 kg block of wood and emerges cleanly at 170 m/s. If the block is stationary

Ann [662]

The distance traveled by the wood after the bullet emerges is 0.16 m.

The given parameters;

mass of the bullet, m = 23 g = 0.023 g
speed of the bullet, u = 230 m/s
mass of the wood, m = 2 kg
final speed of the bullet, v = 170 m/s
coefficient of friction, μ = 0.15

The final velocity of the wood after the bullet hits is calculated as follows;

$m_1u_1 + m_2 u_2 = m_1v_1 + m_2v_2\\\\0.023(230) + 2(0) = 0.023(170) + 2v_2\\\\5.29 = 3.91 + 2v_2\\\\2v_2 = 1.38\\\\v_2 = \frac{1.38}{2} = 0.69 \ m/s$

The acceleration of the wood is calculated as follows;

$\mu = \frac{a}{g} \\\\a = \mu g\\\\a = 0.15 \times 9.8\\\\a = 1.47 \ m/s^2$

The distance traveled by the wood after the bullet emerges is calculated as follows;

$v^2 = v_0^2 + 2as\\\\v^2 = 0 + 2as\\\\v^2 = 2as\\\\s = \frac{v^2}{2a} \\\\s = \frac{(0.69)^2}{2(1.47)} \\\\s = 0.16 \ m$

Thus, the distance traveled by the wood after the bullet emerges is 0.16 m.
