For a 42.0-cm-diameter wheel, consisting of a rim and six spokes,the angular speed is mathematically given as
w=118.6 rad/s
<h3>What is the angular speed?</h3>
Generally, the equation for the Conservation of energy is mathematically given as
K1+U1=K2+U2
Therefore
Mgh+0=0+(1/2)MV2+(1/2)Iω2
Where
M=m+6m
M=2rλ(π+3)
Therefore
w=118.6 rad/s
In conclusion, The angular speed is
w=118.6 rad/s

Answer:
a) Your player
b) Observer's player
c) Each measures their own first
Explanation:
Because given problem is having relative velocity to each other. The person sitting on the train is moving with a very high speed relative to the person standing next to the track.
In this case, the clock situated in the train will be running slow with respect to the stationary frame of reference
Answer:
Explanation:
The fusion reaction in this problem is
The total energy released in the fusion reaction is given by
where
is the speed of light
is the mass defect, which is the mass difference between the mass of the reactants and the mass of the products
For this fusion reaction we have:
is the mass of one nucleus of hydrogen
is the mass of one nucleus of helium
So the mass defect is:
The conversion factor between atomic mass units and kilograms is
So the mass defect is
And so, the energy released is:
Answer:
φ = -7.16 × 10⁴ Nm²/C
Explanation:
q = -3.80 × 10⁻⁶ C
ε₀ = 8.85 10⁻¹² C²/Nm²
By Gauss's law
φ = q/ε₀
as the cube has 6 faces so for one side the flux will
φ =1/6 ( q/ε₀)
φ = 1/6 ( -3.80 × 10⁻⁶ C / 8.85 10⁻¹² C²/Nm²)
φ = -71,563.088 Nm²/C
φ = -7.16 × 10⁴ Nm²/C
Answer:
Yes, the errors are likely to be relevant
Explanation:
A systematic error occurs as a result of the instrument used in carrying out and experiment. These errors are a result of small fluctuations in the measurement properties of the instrument. This happens when the instrument departs from non-ideal situations, for example as a result of physical expansion or change in temperature. For instance, let the resistance be measured to be up to 10 Ω ± 1 Ω
The error of the resistance, ε = 0.01Ω
