In a ballistics test, a 24 g bullet traveling horizontally at 1200 m/s goes through a 31-cm-thick 320 kg stationary target and e

Zanzabum

Answer:

The velocity is $v_t = 0.02175 \ m/s$

Explanation:

From the question we are told that

The mass of the bullet is $m_b = 0.024 \ kg$

The initial speed of the bullet is $u_b = 1200 \ m/s$

The mass of the target is $m_t = 320 \ kg$

The initial velocity of target is $u_t = 0 \ m/s$

The final velocity of the bullet is is $v_b = 910 \ m/s$

Generally according to the law of momentum conservation we have that

$m_b * u_b + m_t * u_t = m_b * v_b + m_t * v_t$

=> $0.024 * 1200 + 320 * 0 = 0.024 * 910 + 320 * v_t$

=> $v_t = 0.02175 \ m/s$

You build a grandfather clock, whose timing is based on a pendulum. You measure its period to be 2s on Earth. You then travel wi

Elenna [48]

Answer:

$\frac{g_{2}}{g_{1}} = \frac{1}{4}$

Explanation:

The period of the simple pendulum is:

$T = 2\pi\cdot \sqrt{\frac{l}{g} }$

Where:

$l$ - Cord length, in m.

$g$ - Gravity constant, in $\frac{m}{s^{2}}$ .

Given that the same pendulum is test on each planet, the following relation is formed:

$T_{1}^{2}\cdot g_{1} = T_{2}^{2}\cdot g_{2}$

The ratio of the gravitational constant on planet CornTeen to the gravitational constant on planet Earth is:

$\frac{g_{2}}{g_{1}} = \left(\frac{T_{1}}{T_{2}} \right)^{2}$

$\frac{g_{2}}{g_{1}} = \left(\frac{2\,s}{4\,s} \right)^{2}$

$\frac{g_{2}}{g_{1}} = \frac{1}{4}$

The quantum mechanical approach to atomic structure permits the calculation of 1. the most probable distance between any two spe

miss Akunina [59]

Answer:

2. a region about the nucleus in which an electron of specified energy will probably be found

Explanation:

With quantum mechanics we can find the wave function that describes the movement of the particles, the interpretation of this wave function is through the probability density (φ* φ).

This probabilistic interpretation of the energies, position and amounts of motion electrons allow us to find the region around the nucleus where an electron of specific energy can be found with a given probability.

A very myopic man has a far point of 32.3 cm. what power contact lens (when on the eye) will correct his distant vision?

Alenkasestr [34]

p=3.0D contact lens is needed to correct his distant vision.

The person is suffering from myopia and hence need a concave lens to correct the defect. The lens should be such that an object at infinity must form its image at the far point.

Hence,f= -32.3cm

= -0.323m

we can define the power of the lens as the reciprocal of its focal length in metre.

The power of lens is the ability to converge and diverge rays of light.

The power of the lens can be obtained as:

p= 1/f

p=1/(-0.323)

p=3.0D

Thus,the power is 3.0D to correct his distant vision.
