Answer:
the true claims
Explanation:
Electric charges obey Newton's second law
F = m a
where the acceleration is centripetal and the force is magnetic
F = q v x B
a = v² / r
we substitute
q v x B = m a
Suppose the magnetic field is perpendicular to the velocity, so the modulus of the vector product is
q v B = m v² / r
r = mv / qB
We see that the radius of the orbit depends on the mass, so if one of the particles has a greater mass, the radius of its orbit is greater and those of the same mass have identical radii of orbit.
therefore the radius of the negative particle must be equal to that of a positive charge and the other positive charge must have a much greater radius
the true claims
Answer:
539.19 m/s , 459.83 m/s , 2156.78 m/s
Explanation:
The formula for the rms speed is given by
Where, R be the gas constant, T be the absolute temperature and M be the molecular mass of the gas
R = 8.314 in SI units
T = 100°C = 100 + 273 = 373 K
For Oxygen:
M = 32 g = 0.032 kg
vrms = 539.19 m/s
For carbon di oxide:
M = 44 g = 0.044 kg
vrms = 459.83 m/s
For hydrogen:
M = 2 g = 0.002 kg
vrms = 2156.78 m/s
Explanation:
Given that,
Mass of block = 2.00 kg
Spring constant = 10.0 N/m
Initial amplitude
Final amplitude
Number of oscillation = 4
(a). We need to calculate the time
Given formula,
Put the value into the formula
We need to calculate the value of b
Using damping formula
(b), The damping force equation is
We know that,
The time period is
Therefore, time period is affected by damping force.
Hence, This is the required solution.
