We all know that there are 365 days in a year, 24 hours in a day, 60 minutes in an hour and lastly 60 seconds in a minute. Round that off to 100, 10, 100 and 100.That will be 10^2 x 10^2 x 10^1 x 10^2 = 10^7 seconds.
0.49 N
On a spring scale that measures force, a reading shows the
force of an object to be about half way between 0 N and 1 N. 0. 49 Newton is
the most accurate measurement for the force.
If we cluster the number values of 0 N to 1 N
It would be 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0
N.
These numbers indicate the micro intervals of 0-1. It cannot
be the other given because the other values are either higher or lower which
exceeds the 0-1 scale. Observe.
That all depends on what kind of quantity you are graphing.
It might be speed, temperature, altitude, relative humidity,
barometric pressure, etc. Each would use a different unit.
Answer:
The final rotation is 2.449 times the initial rotation
Explanation:
Centripetal acceleration and rotation speed of particle is related as
a=rω²
where ω is angular speed and r radius of circle
Rearranging equation
ω=![\sqrt{\frac{a}{r} }](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7Ba%7D%7Br%7D%20%7D)
The initial acceleration is given by
a₁ =100g
The final acceleration of particle is
a₂ = 6 (100g)
=600g
The final and initial rotation speed are related as
![\frac{w1}{w2} =\sqrt{\frac{a2}{a1 }](https://tex.z-dn.net/?f=%5Cfrac%7Bw1%7D%7Bw2%7D%20%3D%5Csqrt%7B%5Cfrac%7Ba2%7D%7Ba1%20%7D)
ω2=![\sqrt{\frac{600g}{100g} } *w1](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7B600g%7D%7B100g%7D%20%7D%20%2Aw1)
ω2=2.449ω1
Explanation:
Approximately 5.9. Using Q=IT then T=Q/I so T=48/8.2=5.8536585366 Hope this helps
