Answer:
Explanation:
11 oscillations in 18.2 s
Time period is defined as the time taken to complete one oscillation.
T = 18.2 / 11 = 1.655 s
mass, m = 290 g = 0.29 kg
Δx = 21.1 cm = 0.211 m
ω = 2π / T = (2 x 3.14) / 1.655 = 3.796 rad/s
Where, K is the spring constant
K = ω² m = 3.796 x 3.796 x 0.29 = 4.18 N/m
Now, mg = K Δx
0.29 x g = 4.18 x 0.211
g = 3.04 m/s²
Answer:
2.28 cm
Explanation:
Radius of the proton if v and B is perpendicular will be,
Now,
mass of proton, .
Radius of the orbit, .
Magnetic field, .
Charge on the proton, .
Now substitute all the variables in r.
.
.
Therefore the radius of the orbit of moving proton is 2.28 cm.
The product of (wavelength) times (frequency) is always the same number ...
the speed of the wave in whatever material it's traveling through. So if the
frequency is increased, then the wavelength must <em><u>de</u></em>crease by the same
factor, in order to keep the product the same.
Answer:modeled as an electromagnetic wave. In this model, a changing electric field creates a changing magnetic field.
