Saturn exerts a much greater force on the moon Pan than Pan exerts on saturn. true or false
shtirl [24]

Answer: False

Explanation:

because according to universal law of gravitation, every object attracts every other object in the universe.

according to the newton's third law, for every action there is equal and opposite reaction.

So, both the saturn and pan exerts same force on each other

But from the newton's second law we have, F = ma   &   a = F/m

so, from the above equation acceleration produced by pan is high compared to the acceleration produced by saturn.

Therefore, acceleration produced by saturn is lower than the acceleration produced by pan

but force exerted by saturn is equal to the force exerted by pan

So, the answer is false

S A pulse traveling along a string of linear mass density μ is described by the wave function
HACTEHA [7]

The power P(x) carried by this wave at a point x = P(x) = (μ ω³ A² e⁻²ᵇˣ)/2k

Power time is the pace at which work is completed or energy is delivered; it is expressed as the product of the work completed (W) and the energy transferred (t), or W/t. The variation in the gas pressure ΔP measured from the equilibrium value is also periodic with the same wave number and angular frequency as for the displacement which is given by

ΔP = ΔPmax sin (kx−ωt)

Power is an expression of energy expended through time (effort), of which force is an element, as opposed to force itself, which is the fundamental outcome of an interaction between two objects. Power can be measured and described, but a force is a real physical entity, but power is not. ​The power is the rate at which the piston is doing work on the element at any instant of time is given by

Power = F ⋅ v

As we mention before in the concept session, the power of the wave is given by

P = ρ ν ω² A s² sin(kx-ωt)

P(x) = 1/2 μ ω² ν A²

      = 1/2 μ ω² ω/2 A² e⁻²ᵇˣ

P(x) = (μ ω³ A² e⁻²ᵇˣ)/2k

So, The final answer of power P(x) is P(x) = (μ ω³ A² e⁻²ᵇˣ)/2k.

An alternating-current (AC) source supplies a sinusoidally varying voltage that can be described with the function v of t is equ
Marrrta [24]

Answer:

ω, the angular frequency of the source equals 377 rad/s

Explanation:

From the question, V(t) = V cosωt.

Now, ω = the angular frequency of the sinusoidal wave is given by

ω = 2πf where f = the frequency of the source = 60 Hz

So, the angular frequency of the source ,ω = 2π × the frequency of the source.

So, ω = 2πf

ω = 2π × 60 Hz

ω = 120π rad/s

ω = 376.99 rad/s

ω ≅ 377 rad/s

So, ω, the angular frequency of the source equals 377 rad/s

What factors determine the distance at which two atoms form a bond ?
dsp73

Answer:

The length of the bond is determined by the number of bonded electrons (the bond order). The higher the bond order, the stronger the pull between the two atoms and the shorter the bond length. Generally, the length of the bond between two atoms is approximately the sum of the covalent radii of the two atoms.

Ancient Greek philosophers spent lots of time thinking about science and imaging explanations for the natural world. What part o
Illusion [34]

Answer:

Testing

Explanation:

Ancient Greek philosophers lived with the ideology to simply contemplate life. This means that their whole life revolved around thinking and questioning everything. This would include creative thinking, because they would sometimes come up with theories which require creativeness. They would often debate with their friends as to why their theory should be accepted or what their opinions were on the matter. More often than not, they argued a lot, and many philosophers went against some powerful people in the community and some were even sentenced to death.

The main process they didn't/couldn't do was the testing. They could never test certain theories because they did not have the means to.
