Explanation:

Moon always keep moving and people usually relate it to the beauty of their loved ones. Even if the moon is not admired for its beauty, it never stops moving. It is never tired of its motion so the best hhyakkendana-hashigozake.comkkendana-hashigozake.com for this riddle is MOON.

You are watching: What is always moving but never tired



The correct hhyakkendana-hashigozake.comkkendana-hashigozake.com is clouds.

Clouds are always on the move. They never ever stop no matter what. They keep moving on in the sky.

But because they are not a living substance like humans or animals, they never get tired of it. Its like their job. Just like the wind.

Clouds might get admired for their beauty but never for their forever movement. So the hhyakkendana-hashigozake.comkkendana-hashigozake.com for this riddle is the clouds.



If silicic rock is found in a core sample. What evidence does this provide about the rocks location ?

hhyakkendana-hashigozake.comkkendana-hashigozake.com:

The rocks location is underneath an ocean or mountain

Explanation:

Silicic rock are igneous rock rich in silica. The amount of silica that constitutes a silicic rock is usually defined as at least sixty three percent. Granite and rhyolite are the most common silicic rocks found. These are found in the magma of the Earth.

Silicic is the group of silicate magmas which crystallise a relatively small proportion of ferromagnesian silicates. The main constituents of a silicic rock will be minerals rich in silica-minerals mainly.

A 1 kg mass is attached to a spring with spring constant 7 Nt/m. What is the frequency of the simple harmonic motion? What is th
Scorpion4ik <409>

1. 0.42 Hz

The frequency of a simple harmonic motion for a spring is given by:

*

where

k = 7 N/m is the spring constant

m = 1 kg is the mass attached to the spring

Substituting these numbers into the formula, we find

*

2. 2.38 s

The period of the harmonic motion is equal to the reciprocal of the frequency:

*

where f = 0.42 Hz is the frequency. Substituting into the formula, we find

*

3. 0.4 m

The amplitude in a simple harmonic motion corresponds to the maximum displacement of the mass-spring system. In this case, the mass is initially displaced by 0.4 m: this means that during its oscillation later, the displacement cannot be larger than this value (otherwise energy conservation would be violated). Therefore, this represents the maximum displacement of the mass-spring system, so it corresponds to the amplitude.

4. 0.19 m

We can solve this part of the problem by using the law of conservation of energy. In fact:

- When the mass is released from equilibrium position, the compression/stretching of the spring is zero:

*
, so the elastic potential energy is zero, and all the mechanical energy of the system is just equal to the kinetic energy of the mass:

*

where m = 1 kg and v = 0.5 m/s is the initial velocity of the mass

- When the spring reaches the maximum compression/stretching (x=A=amplitude), the velocity of the system is zero, so the kinetic energy is zero, and all the mechanical energy is just elastic potential energy:

*

Since the total energy must be conserved, we have:

*

5. Amplitude of the motion: 0.44 m

We can use again the law of conservation of energy.
