stable equilibrium, if displaced from equilibrium, it experiences a net force or torque in a direction opposite to the direction of the displacement.

unstable equilibrium, if displaced it experiences a net force or torque in the same direction as the displacement from equilibrium. A system in unstable equilibrium accelerates away from its equilibrium position if displaced even slightly.

neutral equilibrium, is when an equilibrium is independent of displacements from its original position.

Have a good day, hope this helps

13. A nuclear decay chain represents

murzikaleks [220]

Answer:

a series of decays producing sequentially more stable nuclei

Explanation:

A nuclear decay chain represents a series of decays producing sequentially more stable nuclei.

For every atomic nucleus, there is a specific neutron/proton ratio which ensures the stability of the nucleus.
Any nucleus with a neutron/proton combination different from its stability ratio (i.e either too many neutrons or too many protons) will be unstable and split into one or more other nuclei with the attendant emission of small particles of matter.
The decay process is a continuous chain reaction steps.
Until stability of the nucleus is attain, it continues.

Please help!! i need the answers to both!!!

Allisa [31]

Answer and Explanation:

1. Evidence can be observed that light is energy-consuming because the liquid crystal sheet sets the temperature and gets warmer. With this, we can affirm that the light energy, moved the liquid crystal sheet molecules, making them when they move generate heat.

2. The evidence that light loads energy can be seen through the movement of the toy. This is because the light states that there was energy received, which will make all the gear of the toy work and move it.

(1) Develop an equation that relates the rms voltage of a sine wave to its peak-to-peak voltage. a. If a sine wave has a peak-to

Aleks04 [339]

Answer:

(A) Equation will be $v=v_msin\omega t=0.75sin(18840t)$

(B) RMS value of voltage will be 0.530 volt

Explanation:

We have given peak to peak voltage of ac wave = 1.5 volt

Peak to peak voltage of ac wave is equal to 2 times of peak voltage

So $2v_{peak}=1.5volt$

$v_{peak}=\frac{1.5}{2}=0.75volt$

Frequency of ac wave is given f = 3 kHz

So angular frequency $\omega =2\pi f$ = 2×3.14×3000 = 18840 rad/sec

So expression of equation will be $v=v_msin\omega t=0.75sin(18840t)$ ( As phase difference is 0 )

Now we have to find the rms value of voltage

So rms voltage will be equal to $v_{rms}=\frac{v_{peak}}{\sqrt{2}}=\frac{0.75}{1.414}=0.530volt$

If an object undergoes a change in momentum of 10 kg m/s in 3 seconds what is the force?

kolbaska11 [484]

Answer:

The correct equation for calculating force is change in momentum divided by time. So 10 kg m/s divided by 3 s is 3.3 newtons (N

The dry adiabatic rate of change for unsaturated air is 10°c/1000 m. what does this mean

brilliants [131]

Adiabatic rate is used to describe the change in temperature as a result of the rising or the sinking of an air parcel.

Knowing that the dry adiabatic rate of change for unsaturated air is 10°C/1000 m means that the temperature of the unsaturated air parcel would increase (get warmer) as the air parcel sinks and will decrease (get cooler) as the air parcel rises.

Hope this helps :)
