That's true, you can't get any more precise than what's measured to the least precision.
The less dense areas created as a sound wave propagates are called Rarefactions
Answer:
Stars are born within the clouds of dust and scattered throughout most galaxies. Deep within these clouds, turbulence creates knots with enough mass to cause the gas and dust to collapse under its own gravitational force.
Answer:
<em>The velocity with which the student goes down the bottom of glide is 12.48m/s.</em>
Explanation:
The Non conservative force is defined as a force which do not store energy or get he energy dissipate the energy from the system as the system progress with the motion.
Given are
<em> mass of the student 73 kg</em>
<em> height of water glide 11.8 m</em>
<em> work done as -5.5*10³ J</em>
Have to find speed at which the student goes down the glide.
According to<em> Law of Conservation of energy</em>,
K.E =P.E+Work Done
mv²/2=mgh +W
Rearranging the above eqn for v
v = √2(gh+W/m)
Substituting values,
V = 12.48 m/s.
<em>The velocity with which the student goes down the bottom of glide is 12.48m/s.</em>
Answer:
σ =4.180×10^{-9} C/m^2
Explanation:
electric field due to non conducting sheet is

the force acting on the piece of Styrofoam
Eq= mg
⇒E= mg/q
now,

⇒

charge per unit area (in C/m2) on the plastic sheet σ =4.180×10^{-9} C/m^2
