Which type of heat transfer takes place in gases by the movement of particles through a medium?

Sergeu [11.5K]

Answer: Convention

Explanation: Convention is pretty well known for being a process that transmits heat from one place to another place with the movements of heated particles. I got this answer from my notebook during my chemistry class.

Hope this answer helps!

The range of human hearing is roughly from twenty hertz to twentykilohertz. Based on these limits and a value of 305 m/s for the

AnnyKZ [126]

Answer:

1. $L_s=0.0076\ m$

2. $L_l=7.62\ m$

Explanation:

Given that

f₁= 20 Hz

f₂= 20 KHz

C= 305 m/s

For open pie organ :

$L=\dfrac{C}{2f}$

Shortest length :

$L_s=\dfrac{C}{2f_2}$

$L_s=\dfrac{305}{2\times 20000}$

$L_s=0.0076\ m$

Longest length : 

$L_l=\dfrac{C}{2f_1}$

$L_l=\dfrac{305}{2\times 20}$

$L_l=7.62\ m$

What are 5 fun facts about cytoplasm?

Rufina [12.5K]

You could google it... but here are some facts anyway:
1. cytoplasm is about 80% water but also contains dissolved carbs, proteins and fats.
2. the nucleus has its own type of cytoplasm that is slightly different than that of the rest of the cell. it is called nucleoplasm.
3. when cytoplasm is in a watery state, it is called cytosol and when it's more jelly-like, it is called cytogel
4. in an animal cell, cytoplasm gives the cell its shape.
5. cytoplasm is a good conductor of electricity.

Why is velocity squared in kinetic energy and mass multiplied by 1/2?

maxonik [38]

Remember the definition of work done.
Work done is force(F) times displacement(x)
∴ W = F.Δx
According to Newton's 2nd law of motion,

F = ma
∴ W = ma.Δx ---- (i)
Using the kinematical equation v²-u² = 2ax,
aΔx = (v²-u²)/2

Plug this value in (i),

∴W = m[ $\frac{v^{2}-u^{2} }{2}$ ]
∴W = $\frac{mv^{2} }{2} - \frac{mu^{2} }{2}$

Which is nothing but change in kinetic energy.
That is how kinetic energy is derived

Answer:

Option(a) All of the above;

Explanation:

In relation to physics, force can be defined as any interaction between two bodies or objects that will change their motion. In simpler terms force refers to push/pull of a body with mass m that results in change of velocity or the acceleration a.

The concept of force can be better studied with the help of Newton’s three laws of motion. In it, he explained the nature of action of forces under normal condition
