Which phase of matter consists of particles that vibrate only?

bearhunter [10]

Answer: Solids

Explanation: Solids have very little movement and the particles have barely enough movement to vibrate. We can't see it but the particles are indeed vibrating. Solids have the least amount of kinetic energy which is moving energy.

A small spinning asteroid is in a circular orbit around a star, much like the earth's motion around our sun. The asteroid has a

Fudgin [204]

Answer:

Temperature will be 305 K

Explanation:

We have given The asteroid has a surface area $A=7.70m^2$

Power absorbed P = 3800 watt

Boltzmann constant $\sigma =5.67\times 10^{-8}Wm/K^4$

According to Boltzmann rule power radiated is given by

$P=\sigma AT^4$

$3800=5.67\times 10^{-8}\times 7.70\times T^4$

$T^4=87.0381\times 10^8$

$T=305K$

So temperature will be 305 K

In a lab experiment, two identical gliders on an air track are held together by a piece of string, compressing a spring between

ddd [48]

Answer:

Part a)

$v_2 = -0.300$

Part b)

Here final kinetic energy is more than the initial kinetic energy

This increase in kinetic energy is due to spring connected between them as the spring energy is converted into kinetic energy of two blocks

Explanation:

Part a)

As we know that there is no external force on the system of two gliders

So here we can use momentum conservation for two gliders

So we will have

$m_1 v_1 + m_2 v_2 = (m_1 + m_2)v_i$

$m_1 = m_2$

$1.300 + v_2 = 2(0.500)$

$v_2 = -0.300$

Part b)

now we will have

initial kinetic energy of both gliders is given as

$K_i = \frac{1}{2}(m + m)(0.500)^2$

$K_i = 0.25m$

Final kinetic energy of two gliders

$K_f = \frac{1}{2}m(0.300)^2 + \frac{1}{2}m(1.300)^2$

$K_f = 0.89 m$

so here final kinetic energy is more than the initial kinetic energy

This increase in kinetic energy is due to spring connected between them as the spring energy is converted into kinetic energy of two blocks
